Crop an image to keep a selected rectangle and remove the surrounding pixels. Choose a centered 1:1, 16:9 or 4:3 preset, or enter the rectangle's position and size in source pixels. The overlay shows the selection before download. For example, from a 1600 × 1200 image, choose a centered 1:1 crop to keep a 1200 × 1200 square. To move that square toward an off-center subject, edit X and Y; editing coordinates switches the tool to Free mode. For a round avatar, use [Circle Crop](https://www.toolcomb.com/circle-crop). If the composition is already right but the file needs fewer pixels, use [Resize Image](https://www.toolcomb.com/resize-image) instead. Check the final dimensions with [Image Size Checker](https://www.toolcomb.com/image-size-checker). ## How to Crop an Image - Step by Step 1. **Upload your image** - Choose an image your browser can decode, up to 50 MiB. 2. **Choose a crop** - Select a centered aspect preset or enter X, Y, width and height in source pixels. 3. **Check the rectangle** - Review the overlay and make sure the selection fits inside the source image. 4. **Download** - Choose JPEG, PNG or WebP and select Crop & Download. ## Worked Example - Open Graph 1200×630 Use exact source-pixel coordinates when preparing a social preview image. ### Before Start with a 2400 × 1600 image and decide which part of the photo should remain visible. ### After In Free mode, enter a 1200 × 630 crop rectangle and adjust X and Y to frame the subject. Download the result in your preferred format. A 16:9 crop is a different ratio and does not produce 1200 × 630. If you need to change the output dimensions, use [Resize Image](https://www.toolcomb.com/resize-image). Check the final file size with [Image Size Checker](https://www.toolcomb.com/image-size-checker) before uploading it. ## When You Need Crop - Real-World Use Cases ### 1. Social square posts from DSLR masters Use the 1:1 preset to remove space from the sides of a landscape image. If the subject is off-center, enter a custom rectangle in Free mode. ### 2. YouTube thumbnail safe zones Choose 16:9 for a thumbnail shape, then resize the result separately if you need a specific pixel size such as 1280 × 720. ### 3. E-commerce white-background product cards Marketplaces want tight product bounds. Free mode crops excess padding from studio shots so catalog grids look uniform. PNG output preserves fine edges on jewelry before optional WebP conversion. ### 4. Document scanning cleanup Phone photos of A4 pages include desk background. Crop to the paper rectangle before rotate-flip-image fixes orientation for PDF assembly. Local canvas work avoids uploading sensitive contracts to random crop sites. ### 5. Banner ads with strict aspect For a custom banner size, enter its pixel width and height in Free mode and choose coordinates that fit within the source image. ### 6. Profile header strips Twitter and LinkedIn headers use wide aspect ratios. Crop a landscape vacation photo to the header slot, then compress for faster profile loads on mobile networks without stretching vertical phone shots. ### 7. Game sprite sheets Indie devs slice prototype screenshots into tiles using Free mode coordinates from engine debug overlays. PNG crop keeps alpha for engines that expect straight edges on sprite sheets. ### 8. Real estate listing galleries Agents crop drone stills to highlight the roofline while removing road clutter. Local processing keeps client addresses off third-party servers during listing prep under brokerage privacy rules. ### 9. Slide deck figure exports Consultants crop annotated screenshots to the relevant UI panel before dropping into PowerPoint. Smaller intrinsic dimensions keep email-friendly deck sizes under corporate attachment limits. ### 10. Quick meme templates Frame a square around the subject before using Circle Crop to make a round avatar with transparent corners. ## Crop Image - ToolComb vs Cloud vs Desktop Choose local crop when privacy matters; choose desktop when you need content-aware fill or batch actions. When a notification lists both pixel dimensions and kilobyte caps, treat crop image as the geometry step and compress-to-exact-kb as the byte step - running them in that order avoids over-compressing an oversized bitmap that still fails width checks. Compare options when privacy, batch volume, and format support pull in different directions. ToolComb pages target single-file, browser-local work on locked-down laptops; desktop suites and cloud APIs still win for scripted folders and collaboration - the table below states trade-offs honestly so you pick the right lane before a deadline. | Feature | ToolComb crop | Typical cloud crop | Photoshop / GIMP | | --- | --- | --- | --- | | Local decode/encode | ✓ | Upload required | ✓ | | Aspect presets | ✓ 1:1, 16:9, 4:3 | Varies | ✓ | | Exact pixel coords | ✓ Free mode | Sometimes | ✓ | | Batch folder crop | One file | Often paid | Actions | | 50 MB honest cap | ✓ | Plan limits | RAM | | Content-aware fill | No | Rare | ✓ | Use this tool for a single rectangular crop. Keep the original image if you may need a different framing later; a desktop editor may be more suitable for batch processing or more complex edits. ## Honest Limits of Browser Crop A crop removes pixels outside the selected rectangle; it does not enlarge the image or add new content. Check numeric coordinates when a destination has exact requirements. - **File size:** Images must be at most 50 MiB; large images can still exceed device memory. - **Animation:** An animated GIF becomes a still image. - **Bounds:** The crop rectangle must fit within the source image. - **Preview:** Use the numeric coordinates for precise dimensions. - **Format support:** Input decoding depends on your browser. - **Large images:** Very large images may be slow or fail on devices with limited memory. - **One file at a time:** Batch cropping is not available. - **Metadata:** Exporting can remove image metadata; retain your original if you need it. ## Privacy and Your Image Transforms on ToolComb image tools run entirely in your browser. The page loads JavaScript from this origin; your file bytes are never POSTed to a resize API, never stored in server logs, and never indexed. That local-only model fits unreleased product shots, employee badge photos, and client mockups under NDA - provided you follow your own device and shared-computer policies. We do not persist uploads in localStorage or sync history to an account. Closing the tab drops in-memory previews and canvas buffers. Downloads are new files on disk; originals stay untouched unless you overwrite them manually. Clear Downloads on shared kiosks when finished. Crop coordinates and previews remain in the open page while you work. On a shared device, remember to remove downloaded copies when you are finished. ## How to Choose the Right Image Crop **Start with the destination.** A square product image, a widescreen presentation and a narrow page banner call for different shapes. If a site gives a required aspect ratio, use that ratio to frame the picture; if it gives exact width and height, check those numbers separately before publishing. **Keep the subject inside the frame.** A centered preset is convenient when the subject is already in the middle. For an off-center person or product, enter a custom rectangle and adjust X and Y. X measures from the left edge and Y from the top; width and height describe the part of the source that will be kept. **Leave room for context.** A portrait cropped too tightly can cut off hair or shoulders, and a product crop can remove a useful shadow. Review the whole outline, including anything close to the selection edge. Keep extra space if a destination may crop the image again in a thumbnail. **Check the output size.** A crop removes the pixels outside the selection; it does not enlarge what remains. For example, a 1200 × 630 selection produces a 1200 × 630 image. If you need a different number of pixels after framing, use [Resize Image](https://www.toolcomb.com/resize-image) and inspect the result for sharpness. ## Crop Image Examples and Troubleshooting **Square image for a profile:** Start with a landscape photo and choose 1:1. The preset selects a centered square using the shorter side. If the face is to one side, use Free mode to change the rectangle’s position while keeping its width and height equal. For a round version, continue with [Circle Crop](https://www.toolcomb.com/circle-crop). **Screenshot for a document:** Enter coordinates around the relevant window or diagram to remove surrounding desktop space. Keep enough of the surrounding interface for the screenshot to make sense, and check that any labels or numbers are still visible after the crop. **Selection does not fit:** The X and Y coordinates must be non-negative, and the selected width and height must stay within the original image. Reduce the size or move the rectangle inward if the tool reports that the selection is outside the source. The overlay is a scaled preview; the coordinate fields use source pixels. **File is too large:** Dimensions and file size are different requirements. After cropping, check the saved image with [Image Size Checker](https://www.toolcomb.com/image-size-checker). If a destination also has a size limit, try [Image Compressor](https://www.toolcomb.com/online-image-compressor) and inspect the new file again. Keep the original in case you need to change the framing. ## Frequently Asked Questions ### How do I crop an image online without uploading to a server? Choose an image and set a crop rectangle. The tool processes it in your browser and downloads a new file; the original is not overwritten. ### What aspect ratio presets are available? The centered presets are 1:1, 16:9 and 4:3. Choose Free or edit a coordinate for a custom rectangle. ### Can I enter exact pixel coordinates for the crop? Yes. Enter X and Y from the top-left of the source image, plus the crop width and height in pixels. The rectangle must fit inside the image. ### Does the preview match the exported crop? The overlay shows the selected rectangle scaled over the source preview. The exported crop uses the source coordinates; inspect the downloaded file when precise framing matters. ### What is the maximum upload size? The input limit is 50 MiB. Large images may still exceed the browser's available memory, especially on mobile devices. ### Which output formats can I download? Choose JPEG, PNG or WebP, subject to browser support. PNG can preserve transparency; JPEG cannot. ### How is crop different from circle crop? This tool exports a rectangle. Circle Crop uses a centered square selection and exports a circular image with transparent PNG corners. ### Can I crop on a phone? The page is designed for modern mobile browsers. Format support and processing capacity depend on the browser and device. ### Is the crop tool free? Yes. You can crop and download an image without registration. ### What should I do after cropping? Check the final dimensions and file size against the destination's requirements. You may need to resize or compress the cropped file separately. ## Practical Tips - ToolComb Use this crop image flow when you need a correct file for a portal, CMS, or social upload without installing desktop software. Keep the camera or design master separate from exports so you can retry with different settings. If a destination rejects the download, verify width, height, and kilobytes as separate rules - many forms enforce both. Prefer HTTPS, modern Chrome or Firefox, and a stable tab while large canvases encode. All processing for this tool stays in your browser session on ToolComb. Downloads use a clear`_toolcomb` filename suffix so exports are easy to find beside originals. Closing the tab clears in-memory previews; nothing is retained on ToolComb servers because bytes never upload. On shared computers, clear the Downloads folder when you finish sensitive ID photos, signatures, or geotagged captures. Chain sibling image tools on the same origin when you need crop then resize, resize then exact-KB compress, or EXIF inspect then metadata remove. Browser limits still apply: very large panoramas may hit canvas maximums, animated GIFs flatten to a single frame in still-image encoders, and AVIF support depends on the engine. When in doubt, export a JPEG or PNG intermediate and continue. Document the final pixel size and file weight in your ticket or PR so reviewers can match what the portal or design system expects without opening proprietary suites. ## Related Image Tools Crop often precedes or follows these ToolComb helpers on the same site: All links stay on ToolComb so privacy expectations match this page.
