Choosing an aspect ratio

Square (1:1) crops are the safest choice when you're not sure where an image will end up, since profile pictures and thumbnail grids across most platforms are square. 16:9 is the standard widescreen ratio used for video and most modern displays, so it's a natural fit for video thumbnails or anything meant to fill a widescreen frame. 4:3 was the standard ratio for televisions and monitors before widescreen became the norm, and still shows up in some presentation formats and older camera output. If a specific platform or print size has its own exact requirement, it's worth checking that directly, since these can change — the ratio matters more than the exact pixel count in most cases, because most platforms will resize a correctly-proportioned image automatically.

Frequently asked questions

Does cropping reduce image quality?

No — the crop is applied to the original full-resolution image, not the smaller preview shown on screen, so no quality is lost beyond the crop itself.

What does locking an aspect ratio do?

It keeps the crop box's width and height proportional as you resize it, useful for standard formats like square photos or 16:9 video thumbnails.

Can I move the crop box after resizing it?

Yes — drag anywhere inside the crop box to reposition it without changing its size, or drag the handle in the corner to resize it.

What file format does the cropped image download as?

PNG, which preserves quality losslessly and supports transparency if your source image had any — a good general-purpose choice regardless of what you started with.

Is my image uploaded anywhere?

No. Cropping happens entirely locally in your browser — your image is never sent to a server.
