Cropping is the most effective edit most photographs ever get. Cutting away dead space at the edges pulls the eye to the subject, and it is also the honest way to hit a required aspect ratio — squeezing a landscape photo into a square distorts faces, while cropping it does not.
The cropper here works directly on the original pixels. You drag a rectangle over the image and the tool exports exactly the region inside it, at full source resolution: crop a 1000 × 800 area out of a 6000 × 4000 photo and you get a genuine 1000 × 800 file, not a scaled approximation.
The image is decoded and cropped in your browser. Nothing about the photo — including the parts you cropped away — is transmitted anywhere.
| Ratio | Shape | Where it is used |
|---|---|---|
| 1:1 | Square | Profile pictures, product grids, Instagram posts |
| 4:5 | Tall portrait | The largest footprint a social feed usually allows |
| 16:9 | Wide | Video thumbnails, slide decks, site banners |
| 3:2 | Classic photo | What most cameras shoot; matches 6×4 prints |
| 9:16 | Full-height portrait | Stories, Reels, Shorts |
If you only need padding to a square rather than a genuine crop, the Square Image tool adds white or black bars instead of cutting anything away.
A cropped PNG keeps its alpha channel, so transparent regions inside the selected area stay transparent. A cropped JPEG cannot — the format has no alpha — so the region is painted onto white first. If a transparent PNG must remain transparent, make sure you are not converting it to JPEG at the same time.
The pixels inside your selection are copied at their original resolution, so there is no scaling loss. The only change is the re-encoding step, done at quality 0.92 for JPEG, which is visually lossless.
The crop box is dragged freehand rather than locked to a ratio. Aim by eye using the dimmed area as a guide, and if you need an exact square, the Square Image tool pads to one precisely.
Exactly the size of the region you selected, in original pixels. Selecting a small area of a large photo therefore produces a small file — crop first, then upscale if you need it larger.
The editor works on one image at a time, since the right crop is different for every picture. Process them one after another.
In PNG output, yes. JPEG has no alpha channel, so transparent areas are filled with white before encoding.
No. The picture is decoded into a canvas in your browser and the selected region is exported locally. Nothing is sent over the network.
