What this does
Crops a photo or screenshot to exactly the region you want. Drop an image, drag the selection rectangle into place, optionally lock it to a preset aspect ratio, and download the result in PNG, JPG, or WebP. Every step runs in your browser, so the original file is never uploaded.
Drag a corner or edge handle to resize the selection, drag inside it to move it, and use the grid overlay to line up on the rule of thirds. The readout under the canvas shows the selection's exact pixel size so you can hit a required dimension on the nose.
Which aspect ratio should I use?
- Free: any rectangle. Right for cutting the clutter out of a screenshot or trimming a scan.
- 1:1: square. Profile pictures on almost every service, Instagram grid posts, app icons.
- 16:9: widescreen. YouTube thumbnails, presentation slides, website hero images, most monitors.
- 4:3: the classic photo and iPad shape. Matches 8×6 and 12×9 inch prints and older projectors.
- 3:2: the native ratio of DSLR and mirrorless sensors and of 35mm film. Matches 6×4 inch prints.
- 9:16: vertical video. Instagram Stories and Reels, TikTok, YouTube Shorts, phone wallpapers.
Pick the preset first, then drag; the selection keeps the ratio while you resize. Switching to Free unlocks it again without moving what you already framed.
Does cropping reduce image quality?
The crop itself is lossless: the output is the selected pixels at their original resolution. Select an 800×600 area of a 4000×3000 photo and you get an 800×600 image, not a downscaled one. Quality only comes into play at export. PNG is lossless and the right choice for screenshots, text, and anything with transparency. JPG and WebP are lossy; the quality slider defaults to 92, which is visually indistinguishable from the source for photos while cutting file size substantially. If the cropped image still needs to be smaller in pixels, send it to the image resizer next.
Can I crop HEIC photos from an iPhone?
Yes. HEIC files are decoded on your device by a WebAssembly module that loads on first use, so you can crop straight from the Photos export without converting first. The output format defaults to "same as input", which for HEIC means JPG, since no browser can write HEIC. Choose PNG instead if you need a lossless copy.
What are the size limits?
Input files up to 50 MB and output dimensions up to 8192×8192 pixels. Those limits exist to keep the browser tab within memory, not because a server is involved. Extremely large panoramas may be slow to load on a phone; a desktop browser handles them comfortably.
