Cropping without an upload
This cropper decodes your image in the browser and draws the region you select into a fresh canvas, which is then encoded as the format you pick. The selection you drag is stored in the image's own pixel coordinates rather than screen coordinates, so resizing the window or rotating a phone does not shift what gets cut.
Because there is no upload step, cropping a 40-megapixel photo is as fast as cropping a thumbnail, and the original never leaves your device. That matters for screenshots containing personal data, document photos, and anything else you would not hand to a stranger.
Choosing an aspect ratio
A free crop is right when you are framing for its own sake. Fixed ratios matter when the destination has a fixed shape and will crop for you if you do not.
- 1:1 — profile photos on most social platforms, album art, app icons
- 4:3 — the classic photo shape, and most tablet screens
- 3:2 — the native ratio of most DSLR and mirrorless sensors, and 6×4 prints
- 16:9 — video thumbnails, presentation slides, desktop wallpaper
- 9:16 — phone wallpaper and vertical short-form video
Crop first, then resize
When you need both a specific framing and a specific pixel size, crop here first and resize afterwards. Doing it the other way round means the resize decides the aspect ratio and the crop is left fighting it, which usually ends in a stretched or unexpectedly tight result.
Cropping does not resample the pixels it keeps, so it costs nothing in sharpness. Resizing does resample, which is why it belongs last in the chain — a single resample of an already-framed image is better than resampling twice.
Format and quality
PNG keeps the cropped pixels exactly as they were and preserves transparency, at the cost of a larger file. JPG and WebP re-compress them; at 90% quality the difference is invisible for most photographs and the file is a fraction of the size. When the source was a PNG with transparent areas and you export JPG, those areas are filled with white, because JPG has no alpha channel.
