Crop image online

Crop, rotate and flip a photo

This tool lets you crop an image online: keep the part that matters, rotate the image by a quarter turn, straighten a tilted horizon or flip it like a mirror, then save it as JPG, PNG or WebP. It handles one image at a time (JPG, PNG, WebP, still GIF, and AVIF if your browser can open it). To convert a whole batch, use the image converter on this site instead.

How to crop a photo

1. Drop a photo, click "Choose an image" or paste it.
2. Pick an "Aspect ratio": "Free", a ratio such as 4:3, or a size such as "Square 1080 × 1080". "Portrait ⇄ landscape" swaps it.
3. Drag the box with your mouse or finger, pull its handles, or type "X (px)", "Y (px)", "Width (px)" and "Height (px)".
4. Set the "Format" and "Quality", then click "Download image".

"Undo" and "Redo" (Ctrl + Z, Ctrl + Y) step through every change. With the keyboard, arrow keys move the box and Shift + arrow keys resize it, in steps of 1% of the shorter side.

Crop for a better composition

A good crop removes distractions: a lamp post on the edge, too much empty sky. Tick "Rule of thirds grid" to split the box into nine parts. Put the subject on a line or where two lines cross rather than dead center, and the horizon on the top or bottom line.

Pick a ratio for the job

A 4 × 6 print is exactly 3:2, so a 4:3 phone photo loses a strip at the top and bottom. The pixel sizes ("Vertical portrait 1080 × 1920", "Wide banner 1500 × 500"…) also set the exact final size of the export.

Straighten the horizon

A sloping sea is fixed with "Free rotation", from −45° to +45° in 0.1° steps. Turning the picture opens up empty corners: with "Adjust the box to avoid empty corners", the box shrinks just enough to stay inside the photo. At 10°, it loses about 18% of its width on a 4:3 photo. Without that option, the corners stay transparent in PNG and WebP, white in JPG.

Rotate and flip

"Rotate right" turns the picture a quarter turn clockwise: 4000 × 3000 px becomes 3000 × 4000 px, with no loss. "Flip horizontal" swaps left and right, handy for a mirrored selfie; "Flip vertical" swaps top and bottom. "Circle crop" saves a circle on a transparent background, which suits an avatar; it requires PNG or WebP.

Export quality and size

For a photo, JPG at quality 85 to 90 stays sharp and light; lossless PNG suits screenshots. With "Resize the final image", the height follows the "Final width (px)": a 3000 × 2000 px box exported at width 1200 gives 1200 × 800 px.

Privacy

Everything happens in your browser: nothing is uploaded. Metadata (camera, date, GPS location) is stripped from the saved file.

FAQ

Does cropping reduce quality?

Not without free rotation: the pixels you keep are copied exactly. JPG compresses the file again; choose PNG for a lossless result.

How do I crop to an exact size?

Choose "Free" and type X = 100, Y = 50, Width = 300, Height = 200: you get 300 × 200 px starting at pixel (100, 50) of the original.

Why does my photo show up sideways?

The orientation stored by the phone is applied. If it is still on its side, "Rotate right" sets it straight.

Can I crop an animated GIF?

Only the first frame is kept, so the result is a still image.
