How to crop an image
Choose a PNG, JPG, or WebP file. Enter custom X/Y/width/height values or use a centered 1:1, 4:3, 3:2, or 16:9 preset, then preview and export the crop.
Understanding crop coordinates
X measures pixels from the left edge and Y measures pixels from the top. The crop rectangle must remain inside the original image.
Privacy and limits
The selected image is decoded and rendered inside the current browser tab. MyTool0 does not upload the source file or generated result. A temporary object URL is used for previews and released when the file or result changes. Inputs are limited to 20 MB, 8,192 pixels per side, and 16 megapixels. Animated PNG/WebP inputs are rejected because cropping would otherwise export only one frame without warning. This version uses precise numeric controls rather than a drag handle, which improves repeatability but is less visual.
