JPEG, standardised in 1992, compresses photographs by discarding detail the eye notices least. PNG, created in 1996 as a patent-free replacement for GIF, stores pixels losslessly with full transparency. WebP, from Google in 2010, and AVIF, from the Alliance for Open Media in 2019, aim to deliver the same quality in fewer bytes for the web. BMP, TIFF, and ICO come from the desktop, scanning, and Windows worlds. Real work crosses those boundaries all the time. A phone photo arrives as HEIC and must go into a form that accepts only JPG. A designer's PNG needs to become WebP for a faster page. A scanner exports TIFF that a content system cannot preview. A logo needs to become an ICO. Opening a heavyweight editor for each of these is overkill, and uploading private pictures to a random converter website is a poor trade. The image converter creates one output image in your browser. Choose the format required by your editor, website or form, then inspect the downloaded file. Input and output support can depend on the browser and source. The result is a fast, no-account path for one-off conversions, with sensible defaults: WebP preselected for the web, white fill when flattening transparency for JPG, and a quality slider only for formats where it has meaning. It is not a replacement for a colour-managed print workflow or a batch pipeline, and its limits are listed plainly below so you can pick the right tool for each job. ## How to convert an image between formats Five steps that begin with a decision, because choosing the format is the part that actually affects the outcome. 1. **Decide what the destination actually needs** Check the destination requirements first. JPEG is often used for photos, PNG for graphics and transparency, and WebP for web images. ICO, BMP and TIFF may be useful for specific software. 2. **Load any supported image** Choose or drop one image up to 50 MiB. The browser and device determine which input files can be opened; some additional formats may require resources to load. 3. **Select the output format from the dropdown** The menu lists JPG, PNG, WebP, AVIF, BMP, TIFF, and ICO, with WebP preselected. Switching format updates the options below it: formats with a quality knob show a slider, and lossless or fixed-size formats hide it because there is nothing to tune. 4. **Tune quality only where it applies** Adjust quality for JPG, WebP or AVIF and compare the downloaded result. Transparent pixels are placed on white when exporting JPEG. 5. **Convert, then open the result where it will be used** Press Convert and the download begins immediately with a ToolComb-tagged filename and the new extension. Open the file in the program or upload form it was meant for before deleting the original, so any format surprise shows up while the source is still at hand. ## Worked example: one photo, three destinations ### Before A volunteer coordinator has one 4000 by 3000 pixel photograph, 5.8 MB as a JPG, from a community event. She needs it on the charity's website, in a printed newsletter template that takes only PNG, and as a small attachment for a grant portal that caps uploads at 500 KB. ### After She converts a copy to WebP for the website and checks its appearance and file size. For the newsletter and application she follows each destination’s format and dimension requirements, retaining the original for further edits. Each file was produced on her own laptop without signing in. She keeps the original JPG as the archive copy and treats the three outputs as disposable derivatives, regenerating them when a different crop or size is needed. ## Everyday jobs for a universal converter ### 1. Making images acceptable to upload forms Government portals, job sites, and HR systems often list accepted formats narrowly, commonly JPG or PNG. Converting from HEIC, WebP, or AVIF solves the rejection quickly. ### 2. Web performance optimisation Exporting PNG screenshots or large JPG banners to WebP can cut page weight substantially. Comparing sizes across formats on the same source shows which gives the biggest saving. ### 3. Preparing assets for design tools When a plugin or application cannot open a newer format, PNG is the dependable intermediate that keeps transparency and quality while you edit. ### 4. Digitising scans and legacy files Old scans in BMP or TIFF are large and awkward to share. Converting to JPG or WebP produces files that email clients and messaging apps display directly. ### 5. Creating favicons and Windows icons Selecting ICO produces a single-image icon file from a logo, handy for a quick favicon or desktop shortcut. ### 6. Supporting older software and hardware Label printers, medical viewers, and industrial controllers sometimes accept only BMP or TIFF. Exporting those formats avoids installing extra converters on locked-down machines. ### 7. Testing format support QA engineers produce the same image in several formats to check how a site, app, or CMS handles each, including the odd ones like BMP. ### 8. Privacy-sensitive documents For sensitive images, remember that processing happens in your browser. Metadata can change during conversion; inspect the downloaded file and manage copies on shared devices. ### 9. Teaching and learning Students can see how choices of format and quality affect file size by exporting the same picture repeatedly and comparing the numbers. ### 10. Quick fixes during publishing deadlines Editors who receive pictures in mixed formats can standardise everything to one type in seconds, without waiting for a developer or installing software. ## Choosing an output format This table summarises what each target offers in this tool, so you can match the format to the job. | Format | Compression | Transparency | Best used for | | --- | --- | --- | --- | | JPG | Lossy, quality slider | No, flattened to white | Photos that must open everywhere | | PNG | Lossless | Yes | Screenshots, logos, editing intermediates | | WebP | Lossy, quality slider | Yes | Web delivery with small files | | AVIF | Quality slider; browser support varies | Check output | Web delivery when the destination supports it | | BMP | None, 24-bit uncompressed | No | Legacy Windows software and simple pipelines | | TIFF | Uncompressed RGBA | Yes | Archival, scanning, and print workflows | | ICO | PNG inside an icon container | Yes | Favicons and Windows icons, one image up to 256 px | Choose the format your destination accepts. Compare file size, dimensions, transparency and visual quality instead of assuming one format is always best. ## Limits of the converter - One image per run, up to 50 MB. There is no folder or batch mode. - Animated GIF, WebP, and AVIF inputs are converted from a single frame. - Converting between lossy formats compounds quality loss. Keep the original and convert once. - Metadata and embedded color profiles may change or be omitted. Keep the original if these details matter. - AVIF encoding depends on your browser, and some browsers cannot write it. Check the output file after conversion. - BMP output is 24-bit without alpha, and the TIFF is a single uncompressed image rather than a multi-page or CMYK file. - The ICO output contains one image up to 256 pixels. It is not a full multi-resolution icon set. - Very large pixel dimensions can exceed browser canvas limits or run out of memory, particularly on mobile devices. ## How your files are handled Images are read through the File API, processed on a canvas in your tab, and delivered via the browser's download feature. No upload endpoint receives them. Some input formats may need additional resources to load. Processing runs in the browser; downloaded copies remain on the device. The page does not require an account. When you finish, close the tab to release memory and delete downloaded outputs you no longer need. ## Frequently Asked Questions ### Which formats can I convert from and to? Choose an image your browser or the page can decode, then select JPG, PNG, WebP, AVIF, BMP, TIFF or ICO. Support varies by device and file; animated inputs become a still image. ### How do I choose between JPG, PNG, and WebP? Choose the format accepted by the destination. JPG is commonly used for photos; PNG supports lossless storage and transparency; WebP can be useful for the web. Compare actual sizes and visual quality. ### Will converting reduce my image quality? JPEG, WebP and AVIF output may reduce detail. A format conversion cannot recover detail already lost; check the downloaded image and retain the original. ### What happens to transparent backgrounds? JPG does not support transparency and this converter places transparent areas on white. Some other outputs support transparency; inspect the downloaded file in its destination. ### Does my image get uploaded to ToolComb or anyone else? No. Decoding, canvas drawing, and encoding all run inside your tab, and the finished file is saved through the browser's download mechanism. The only network traffic is loading the page and, for HEIC or TIFF, fetching the decoder code. You can confirm by watching the browser's Network panel during a conversion. ### Why does AVIF sometimes fail or produce an unexpected file? AVIF encoding support varies by browser. If encoding is unavailable the tool reports an error; try a supported format or browser. ### Is the ICO I get a multi-size icon? The ICO output contains one image up to 256 pixels, centered in a square. It is not a multi-size ICO. Favicon Generator provides separate PNG icons. ### Are metadata and colour profiles preserved? Metadata and color profiles may be omitted or changed in the converted file. Keep the original if these details matter, and inspect the result before sharing. ### Is there a limit on file size or batch size? Each run handles one file up to 50 MiB. Large pixel dimensions can exceed browser or device memory, especially on phones. ### Should I use this or the single-purpose converters on the site? This page offers several output formats. Dedicated converter pages can be useful when you already know the format you need; behavior and browser support can differ across pages. ## Dedicated converters for specific pairs - [Image to JPG](https://www.toolcomb.com/image-to-jpg) - Create a JPEG copy when a destination requests JPG. - [Image to PNG](https://www.toolcomb.com/image-to-png) - Create a PNG copy for a compatible editor or upload. - [Image Size Checker](https://www.toolcomb.com/image-size-checker) - Inspect the saved file's dimensions and size. - [HEIC to JPG](https://www.toolcomb.com/heic-to-jpg) - Open iPhone photos in software that only knows JPEG. - [PNG to JPG](https://www.toolcomb.com/png-to-jpg) - Shrink screenshots and flatten transparency. - [Image to WebP](https://www.toolcomb.com/image-to-webp) - Prepare images for faster web pages. - [Image to ICO](https://www.toolcomb.com/image-to-ico) - Build an icon file from a logo. ## Related Tools Discover more free tools that might help with your next task.
