How your files are processed
Files are uploaded and processed on our servers, then made available for download.
What this tool does
Crop image keeps the rectangle you draw in the preview and exports that crop as a new raster.
Square profile shots, strip scanner margins, or match ad units without opening Photoshop.
- Raster in, raster out — Crop image reads common JPEG, PNG, and WebP sources and writes the file type the form advertises—alpha PNG, recompressed JPEG, or plain TXT for OCR.
- Server-side models — Matting, geometry, and OCR use tuned backends instead of single-threaded in-tab scripts on huge files.
- Still too big? — After editing, run the matching compressor profile if email or mobile data still rejects the bytes.
How to use Crop image?
- Upload — choose the file (or files, if the tool allows multiple) in the supported formats listed on this page.
- Configure — set options such as dimensions, watermark text, or OCR language using the fields above.
- Run and download — submit the job, wait for processing, then download your result before the automatic expiry window.
Why use Crop image?
Crop image pairs an on-page marquee with server-side raster cuts—handy for Instagram squares, banner slices, or trimming scanner noise.
Coordinates baked into the download match what you saw in the preview grid.
Common uses for Crop image
- Square a photo for profile or thumbnail grids.
- Remove scanner margins or unwanted UI from screenshots.
- Match strict dimension requirements for ads or CMS slots.
- Drop results into Slack threads—the /tools/crop-image crop image flow matches Windows and macOS Chrome.
Output quality tips for Crop image
Sharpness depends on source resolution, JPEG quality sliders, and whether the tool re-saves lossy formats.
Keep a PNG or TIFF master before you distribute aggressive JPEG. Compare downloads zoomed to 100% before you replace archive copies.
Crop image: /utilities vs server image tool
Browser utilities (/utilities)
Color pickers, EXIF viewers, and text helpers run as JavaScript in your tab. Bitmaps you open there never upload to FileConvert.
This image tool (upload)
Crop image locks the crop rectangle you draw and writes a new JPEG or PNG at exact pixel dimensions—cropping in-browser stalls on 60 MP RAW exports.
Sketch crops in /utilities only when files stay tiny. Choose Crop image for precise pixel boxes and huge uploads.
Troubleshooting
- Upload fails or stalls: refresh the page, try another browser, or pause strict blockers for this site.
- Extension mismatch: compare your filename with the types named on this page above the upload control.
- Unexpected output: verify time ranges, pixel boxes, OCR languages, or watermark opacity, then rerun once.
- Large file limitations: Crop image jobs can exceed upload or processing limits; try a smaller image first.
- Viewer differences: Safari, Chrome, and design apps tint PNG or WebP differently—open the download in the final app before publishing.
