How do I crop an image to a specific ratio?

Pick a preset such as square, 16:9, or a print size, and the crop box holds that proportion while you drag and resize it.

Can I crop to print sizes like 4x6 or 8x10?

Yes. Presets for 4x6, 5x7, and 8x10 let you crop to the exact print proportion so a lab does not trim your photo unexpectedly.

Does cropping reduce quality?

No. Cropping only removes pixels from the edges; the part you keep is untouched. Saving as PNG is lossless, and JPEG re-encodes the kept area once.

Are my images uploaded?

No. Cropping happens entirely in your browser and the image is never uploaded.

Crop an image in your browser

Drag the box to the part you want to keep. Pick a ratio — square for a profile picture, 16:9 for a thumbnail, a print size like 4×6 — and it stays locked while you drag. Runs on your machine; nothing is uploaded.

Cropping to a ratio, not just a size

Most of the time the reason you're cropping is to fit a shape: a square avatar, a 16:9 video thumbnail, a 4×6 print. The trouble is that dragging a box freehand almost never lands on the exact ratio, and being a few pixels off means the site you upload to crops it again — badly. Locking the ratio first means the box can only ever be the shape you need, however you drag it.

Pick a preset and the crop box holds that proportion while you move and resize it. Choose Freeform to drag each edge independently when you just want to trim, or Original to keep the photo's own proportions while cutting it down.

What the presets are for

1:1 — profile pictures on nearly every platform, and album-style square posts.
4:5 — the tallest portrait most social feeds allow, so it takes up the most screen without being cropped.
16:9 and 9:16 — video thumbnails and widescreen images; 9:16 is the vertical shape for stories and short video.
3:2 and 2:3 — the native shape of most camera photos, and standard for many prints.
4×6, 5×7, 8×10 — the common photo-print sizes. Crop to these before ordering prints so the lab doesn't cut off someone's head to make your photo fit.

The grid is there on purpose

The crop box is divided into thirds. It's a photographer's guide: placing the subject along one of those lines, or where they cross, usually makes a stronger image than centering everything. Ignore it if you like, but it's a good nudge when you're deciding exactly where to cut.

Quality and format

Cropping only removes pixels from the edges — the part you keep is untouched, so there's no quality loss from the crop itself. Saving as JPG re-encodes the kept area once, which is normally invisible; saving as PNG is fully lossless. Leave the format on "same as original" unless you have a reason to change it. And as with every tool here, the image is cropped in your browser and never uploaded.
