Crop image guide
Crop JPG, PNG or WebP files using the same pixel rectangle across a batch.
Open Crop image →Before you start
Keep the originals. Choose static JPG, PNG or WebP files. Try a small representative sample before running a large batch.
The queue accepts up to 100 files with the same settings applied to each image.
Steps and settings
- Add JPG, PNG or WebP images to the queue.
- Choose the left and top offsets, width and height. Leave width or height blank to use the remaining area of each image.
- Create results and inspect the previews below the workspace before downloading.
Use the queue arrows to change order, or remove files before starting. Cancel stops the current job. If you change the queue or settings after export, create a fresh result.
Check the output
Check the smallest image first. A rectangle outside any input stops the batch and identifies the file.
Each file produces its own PNG. Check the displayed previews, then open a downloaded copy at full resolution to inspect details.
Limits and troubleshooting
Images are limited to 50 MiB each, 100 MiB combined, 24 megapixels and 30,000 pixels per edge. Background processing needs browser support for workers and OffscreenCanvas.
Combined PNG results are limited to 150 MiB. Download individual results when they exceed the 75 MiB ZIP limit. If a job fails, split the batch and try again.
Frequently asked questions
Do crop settings apply to every image?
Yes. Pixel coordinates apply to each image independently; use separate batches when the images need different crops.
Are the inputs uploaded?
The processing runs in your browser. The site can still make its normal hosting and advertising requests.
Where are the previews and downloads?
They appear below the workspace after the job succeeds. Changing the inputs or settings clears old results.
