About Precise Image Cropper
The visual cropper is better for one-off work; this one is better when you already know the numbers — matching a spec, reproducing a crop across several images, or cutting a known region out of a screenshot.
How to use it
- Choose an image, or drag one onto the drop zone.
- Set crop by, aspect ratio and anchor and the remaining options.
- Check the preview, then download. Your original file is never modified.

Questions
What does the aspect ratio option change?
It offers 8 choices — 1:1, 4:3, 3:2 and 16:9 and more. The default is 1:1, which suits most cases; change it when your input or your destination calls for something specific.
Which file types can I use?
JPG, PNG, WEBP, GIF, BMP, AVIF and SVG — anything your browser can display. Because decoding is handled by your browser rather than a conversion server, support tracks whatever your browser can already open.
Is there a file size limit?
No imposed limit — there is no server quota to hit. The real ceiling is your device's memory, since the whole file is held in RAM while it is processed. Desktop browsers cope with very large files; phones give up sooner.
