What it does

An image cropper that lets you drag a selection over your photo and export just that region at full resolution, keeping the original pixels with no quality loss.

Cropping is one of the most common edits: trimming an avatar to a square, cutting distracting edges out of a screenshot, focusing on the subject, or removing a border. Drag a rectangle over the part you want to keep and discard the rest.

Because the crop runs on your device, your image never leaves it, and nothing is uploaded to a server.

How it works in your browser

Cropping happens entirely in your browser with the Canvas API, so it is instant. Your original file is never modified; you download a new image containing only the cropped region, and the parts outside your selection are simply not included in the output.

Lossless by design

The crop is lossless in the sense that the pixels inside your selection are kept exactly as they were. Nothing is scaled or re-compressed beyond saving the file, so the kept region looks identical to the original.

Format and transparency

JPEG photos are saved as JPG, and other formats are saved as PNG, so transparency is preserved where the original had it, which matters for logos and graphics with see-through areas.

Frequently asked questions

Is my image uploaded to a server?

No. Cropping happens entirely in your browser with the Canvas API, so your image never leaves your device.

Does cropping lose quality?

No. It keeps the original pixels inside your selection at full resolution, so there is no quality loss.

What format do I get back?

JPEGs are saved as JPG and everything else as PNG, so transparency is preserved where it exists.

What happens to the parts outside my selection?

They are discarded from the output. You download a new image containing only the region you selected, and your original file is left untouched.

Can I crop a transparent PNG?

Yes. Non-JPEG images are saved as PNG, so any transparency in the original is preserved in the cropped result.
