Cropping is composition: cut away the distracting edges and the subject stands up. Drag the frame over the part of the photo you want to keep, use an aspect preset when a site demands a shape — square for profiles, 16:9 for video covers, 4:5 for portrait posts — and download exactly that rectangle, at full original resolution.
Resolution: what cropping costs
A crop keeps a subset of the original pixels, so the result's dimensions are shown live under the frame — that number is the honest quality of your crop. Cropping to a quarter of the frame keeps a quarter of the pixels in each direction (a sixteenth of the data): fine for a profile picture, soft as a poster. The tool never upscales silently to hide that.
Aspect ratios worth memorising
1:1 — avatars and product grids. 4:5 — the largest portrait shape most social feeds allow, so it takes the most screen. 3:2 — the classic photo print (6 × 4 in). 16:9 — video and presentation covers. 3:4 — portrait prints and phone wallpapers. Official photos (passports, visas) publish exact millimetre sizes that differ by country — crop to the ratio here, then confirm final pixel dimensions against the authority's specification.
Worked example
Use the sample photo and choose the 1:1 preset: the frame becomes a square over the mountains. Drag it so the sun sits in a corner, press Crop & download, and the result is a true square image at the full resolution of the area you framed — the panel under the photo states its exact pixel size before you commit.
How to use this tool
- Drop your image onto the box (or use the sample photo).
- Optionally pick an aspect preset — the frame snaps to that shape.
- Drag the frame to move it; drag its corner dots to resize it.
- Watch the crop's exact pixel size under the photo.
- Choose PNG, JPG or WebP and press Crop & download.
The rule of thirds, in one line
Place the subject a third of the way across the frame rather than dead centre, and horizons on a third line rather than the middle — the crop panel's live dimensions make it easy to nudge the frame a few percent at a time until it feels right.
