Batch-convert multiple JPG, PNG, or WebP files into a single multi-page PDF - no sign-up, no watermarks, no file uploads to any server. Free forever. ## What Is an Image to PDF Converter? An **image to PDF converter** is a tool that transforms image files - JPG, PNG, WebP, and other formats - into PDF (Portable Document Format) documents. PDF is the universal standard for document sharing because it preserves exact formatting, fonts, and image quality across every device, operating system, and printer without requiring any special software to view. Our **free online image to PDF converter** runs entirely in your browser using local PDF processing. This means your images are **never uploaded to any server** - conversion happens locally on your device. This is fundamentally different from most online converters that send your files to a remote server for processing, creating privacy and security risks. Whether you need to **convert a single JPG photo to PDF** for an email attachment, **merge 20 PNG scans into a single PDF document** for submission, or **batch-convert a WebP image collection to PDF** for archiving, this tool handles it all - free, instant, and without watermarks. ### How to Convert Images to PDF - Step-by-Step Guide 1. **Add images** Choose or drop JPG, PNG, or WebP images. Each selection accepts up to 50 files, with a 10 MiB limit per image. 2. **Choose layout** Select A4, Letter or Legal, portrait or landscape, and a margin. Each image is fitted onto its own page. 3. **Set quality and name** Choose an image-quality setting and an output filename. Quality mainly affects images that need conversion before embedding. 4. **Convert and download** Select Convert to PDF, download the result, and review the page order and appearance. For example, add two document scans in the order you want them to appear, select a page size and download the PDF. If the pages later need rearranging, use [PDF Organizer](https://www.toolcomb.com/pdf-organize). Images of text remain images; conversion does not make them searchable. ### Supported Image Formats - JPG, PNG, WebP to PDF This converter supports the three most widely used image formats on the web and mobile devices. Here's what makes each format unique and when to use it: #### JPG / JPEG to PDF JPEG (Joint Photographic Experts Group) is the most common format for photographs, scanned documents, and camera images. It uses lossy compression to keep file sizes small while maintaining good visual quality. JPG files from any camera, scanner, phone, or screenshot tool convert directly to PDF with full quality preservation. **Best for:** Photos, scanned documents, receipts, invoices, ID documents, product images, and any image from a digital camera or scanner. #### PNG to PDF PNG (Portable Network Graphics) uses lossless compression - no quality is lost when saving. It supports transparency (alpha channel), making it the standard for logos, UI screenshots, graphics with text, and technical diagrams. PNG files may be larger than JPEGs but preserve every pixel perfectly. Transparent backgrounds in PNG files are rendered on a white background in the PDF output. **Best for:** Screenshots, UI mockups, logos, graphics with text, technical diagrams, charts, whiteboard photos, and any image where text clarity matters. #### WebP to PDF WebP is Google's modern image format that delivers superior compression compared to JPG and PNG while maintaining high quality. It's widely used for web images and downloaded files from Chrome, Edge, and web applications. WebP supports both lossy and lossless compression, as well as transparency. Our converter handles WebP files seamlessly via canvas conversion. **Best for:** Images downloaded from websites, Google Images, web app screenshots, modern web content, and any image saved from a Chromium-based browser. ### Common Use Cases - When to Convert Images to PDF **Scan Documents to PDF** Photograph physical documents (contracts, certificates, tax forms, utility bills, passports) with your phone camera and convert to PDF for digital storage and sharing. A properly-lit JPG photo of an A4 document converts to a clean, professional-looking PDF that's universally accepted for official submissions. **Merge Multiple Images into One PDF** Upload multiple images in one batch and convert them into a single multi-page PDF. Ideal for creating photo albums, combining pages of a multi-page form photographed separately, assembling a portfolio, or packaging a set of screenshots into a single document for sharing. **Convert Receipts & Invoices to PDF** Photograph paper receipts, invoices, and expense documents and convert to PDF for expense reporting, bookkeeping, and reimbursement submissions. Most accounting software and expense management platforms (Expensify, Concur, Zoho Expense) accept PDF attachments - making image-to-PDF conversion a daily tool for business travelers and freelancers. **Create PDF Portfolios from Images** Designers, photographers, and artists can convert a folder of JPG or PNG images into a multi-page PDF portfolio. Set page size to A4 or Letter, use no margins for full-bleed image layout, and convert your entire project folder into a single shareable PDF that looks professional on screen and in print. **Convert Screenshots to PDF Reports** Capture multiple screenshots of dashboards, analytics reports, error logs, or web content and batch-convert them into a structured PDF report. This is especially useful for QA testers, digital marketers reporting campaign metrics, and developers documenting bug reports. **Convert Phone Photos to PDF for Submission** Many official portals (government forms, university admissions, insurance claims, loan applications) require document submission in PDF format only. If you've photographed your documents with your phone as JPG images, this converter lets you prepare submission-ready PDFs without any installed software. **Create Printable PDF Books from Images** Comic artists, scrapbook creators, recipe photographers, and content creators can assemble JPG or PNG image pages into a multi-page PDF book. The converter scales each image to fit the chosen page size proportionally, ensuring a consistent page layout throughout the document. **Archive Images as PDF for Long-Term Storage** PDF/A is the ISO-standardized archival format for long-term document preservation. Converting important images - family documents, historical photos, property records - to PDF ensures they remain accessible and properly structured for decades without format compatibility concerns. ### PDF Page Size & Settings Guide | Page Size | Dimensions | Standard In | Best For | | --- | --- | --- | --- | | A4 (Portrait) | 210 × 297 mm / 8.27 × 11.69 in | International (ISO 216) | Documents, forms, letters, reports - used everywhere except North America | | A4 (Landscape) | 297 × 210 mm / 11.69 × 8.27 in | International | Wide images, spreadsheet screenshots, panoramic photos | | Letter (Portrait) | 8.5 × 11 in / 216 × 279 mm | USA, Canada, Mexico | US documents, resumes, legal forms, business reports | | Letter (Landscape) | 11 × 8.5 in / 279 × 216 mm | USA, Canada | Presentations, wide charts, horizontal images | | Legal (Portrait) | 8.5 × 14 in / 216 × 356 mm | USA, Philippines | Legal contracts, affidavits, government forms requiring extra length | #### Quality Settings **High (95%):** Maximum image fidelity. Choose this for print-ready PDFs, photo portfolios, and any document where image sharpness is critical. Results in larger file sizes (typically 200KB–2MB per page). **Medium (85%):** The best balance for most use cases - excellent visual quality with noticeably smaller file sizes. Ideal for email attachments, digital submissions, and sharing. **Low (75%):** Smallest output file. Use for web-optimized PDFs, quick previews, or when file size is more important than pixel-perfect quality. #### Orientation Guide **Portrait:** Taller than wide. The standard for most documents - letters, forms, ID scans, book pages. If your images are taller than they are wide, portrait orientation will fit them best. **Landscape:** Wider than tall. Best when your images are horizontal - wide panoramas, screenshots of widescreen monitors, website captures, and spreadsheet exports. _Tip:_ The converter automatically scales images to fit within the page regardless of orientation, maintaining the correct aspect ratio. #### Margin Guide **None:** Image fills the entire page with no border. Use for full-bleed photo prints, artistic portfolios, and backgrounds. **Small (5mm):** Minimal border on all sides. Good for document scans and receipts where you want maximum content area. **Medium (10mm):** Standard document margin. Professional look for reports and formal documents. **Large (15mm):** Generous white space. Best for presentations and documents that will be printed and bound. ### 100% Private - Your Images Never Leave Your Device The most important differentiator of this converter is its **privacy-first architecture**. Unlike every major online image-to-PDF service (Smallpdf, ILovePDF, Adobe Acrobat Online, PDF2Go), this tool processes your images entirely in your browser using client-side JavaScript. **✓ Zero server uploads** Your image files are never transmitted to any server, cloud, or third-party service. Conversion uses your CPU and browser memory only. **✓ No file storage** Unlike services that 'delete files after X hours,' there's nothing to delete - your files were never stored anywhere to begin with. **✓ No account required** No email, no registration, no cookies beyond what your browser sets locally. Open the page, convert, done. **✓ HTTPS encrypted page** The tool runs over HTTPS, ensuring no third party can intercept the connection between your browser and the page. **✓ Safe for sensitive documents** ID documents, passports, medical records, financial statements, legal contracts - all safe to convert here because nothing leaves your device. **✓ Works offline once loaded** Once the page and local PDF processing are loaded, internet connection is not required for the actual conversion process. ### Convert Images to PDF on Any Device - Platform Guide **iPhone / iOS - Convert Photos to PDF** Open this page in Safari or Chrome on your iPhone. Tap 'Choose Images' and select photos from your Camera Roll or Files app. JPG photos from your iPhone camera are directly supported. After converting, tap 'Download PDF' to save to your Files app or share via AirDrop, iMessage, or email. No app download required. **Android - JPG to PDF on Phone** Open this page in Chrome on your Android phone. Tap 'Choose Images' to select from your Gallery, Google Photos, or file manager. Photos from your Android camera (saved as JPG) convert perfectly. Download the PDF to your Downloads folder or share directly to WhatsApp, Gmail, or Drive. **Windows PC - Convert Images to PDF** Open this page in any browser (Chrome, Edge, Firefox). Drag and drop image files from File Explorer directly onto the upload area, or click 'Choose Images' to browse. Batch-select multiple files (Ctrl+Click) to convert many images to a single multi-page PDF at once. The downloaded PDF saves to your Downloads folder. **Mac - Photo to PDF Conversion** Open this page in Safari or Chrome on your Mac. Drag images directly from Finder or your Desktop onto the upload zone. Command+Click to select multiple images at once. While Mac's built-in Preview can create PDFs from images, this tool gives you more control over quality, page size, and margins. ### How Image Quality Is Preserved During PDF Conversion A common concern when converting images to PDF is whether the process will degrade image quality. Here's exactly how this tool handles image quality at each step: **JPG images are embedded directly:** JPG files are placed in the PDF without changing the original image data, so a high-quality photo retains the same quality in the PDF. **PNG images are embedded losslessly:** PNG files keep their image data when placed in the PDF. If a PNG needs compatibility conversion, it is converted to JPEG using the selected quality setting. Transparent backgrounds are rendered as white. **WebP is converted via canvas:** WebP format is not natively supported in PDF, so WebP images are drawn to an HTML canvas element and exported as high-quality JPEG (at your chosen quality setting: 95%, 85%, or 75%) before embedding in the PDF. The canvas conversion is pixel-accurate. **Images are scaled to fit - not stretched or cropped:** Each image is scaled proportionally to fit within the content area of the selected page size. The aspect ratio is always preserved - an image is never distorted, cropped, or stretched. It's simply scaled down if necessary to fit within the page margins. **Resolution is preserved:** The converter does not reduce image resolution. A 4000×3000 pixel photo embedded in an A4 page will print at high DPI. PDF viewers and printers use the full-resolution embedded image, not a downsampled preview. ### Frequently Asked Questions - Image to PDF Converter #### Can I combine multiple images in one PDF? Yes. Choose JPG, PNG or WebP files and create one PDF with a page for each image. Check the page order before sharing. #### How can I change page order? This page does not offer an image-reordering control. Add the files in the desired order, or use a PDF page organizer on the exported file. #### What are the upload limits? Each file can be up to 10 MiB and one selection accepts up to 50 files. Large or numerous images can still exceed the device's available memory. #### Will the PDF look exactly like my images? Images are fitted proportionally within the selected page and margins. Some formats or files may need conversion, and results can vary. Review the downloaded PDF. #### Does the quality control affect every input? JPG and compatible PNG files are normally embedded directly. The quality setting affects images converted to JPEG for embedding, such as WebP or PNG files that need a fallback. #### Can I convert an image of text into searchable PDF text? No. The image remains an image in the PDF; this tool does not add an OCR text layer. #### Does conversion upload my images? The PDF is created in your browser. Downloaded copies remain on your device, so handle them carefully on a shared computer. #### Which page size should I use? Choose the page size required by the recipient, and use portrait or landscape to suit the image. Check the exported PDF before submission. ## Related Tools Discover more free tools that might help with your next task.
