About
Crop photos in the browser with freeform or locked ratios (1:1, 4:3, 3:2, 16:9, 9:16). The crop box uses an inset outline so edges stay visible. Nothing is uploaded.
Export is the cropped rectangle only. JPEG, WebP, and AVIF are re-encoded at quality 0.92; PNG stays lossless. This is not a lossless JPEG crop — recompression can add a little generation loss.
One file at a time. Inputs above 32 megapixels or 50 MB are rejected.
Common use cases
- Square a profile photo
- Cut a 16:9 thumbnail
- Trim scanned edges
- Frame a 9:16 story still
How the crop is applied
The box is normalized to the image, then we copy those pixels onto a new canvas. What you download is only the inside of the box.
Preview can look slightly soft because the on-screen image is scaled. Export uses the full-resolution crop.
Crop vs resize
Crop throws pixels away. Resize changes the remaining box. A common path is crop to 1:1, then Resize Image to 1080px.
Rotate first if the photo is sideways. Crop does not apply Exif orientation as its own step.
When not to use this tool
It will not perspective-correct a building, content-aware fill a hole, or crop a PDF page — use StackPDF Crop & Resize for page boxes. It will not keep a lossless JPEG MCU crop.
Skip huge originals above 32 megapixels. Downscale first, or use a desktop editor.
