Image Cropper

Drag to crop, lock to any feed shape, straighten, or cut a circle — full resolution, no upload, no watermark.

How it works

How to crop an image?

  1. Open the picture

    Drag in a JPG, PNG, WebP, GIF, AVIF or BMP, or pick one. It is read straight off your device — nothing is uploaded, so there is no size cap and no queue.

  2. Drag the box over what you want

    Move the box with your finger or the mouse and pull a corner to resize it. Lock it to a shape — square, 4:5, 9:16 — or type the four numbers if you were handed a spec.

  3. Turn it, straighten it, round it off

    Rotate in quarter turns, mirror it, level a tilted horizon with the straighten slider, and cut the corners round or into a circle if it is going to be a profile picture.

  4. Download the crop

    Save as PNG, JPG or WebP at the crop’s own resolution, or resize it to an exact width on the way out. Nothing is stamped in the corner.

Picking a shape

Which crop ratio to use?

Every feed has an opinion about the shape of a picture, and the one it does not get it crops for you — around the middle, which is rarely where the subject is. Lock the ratio here instead and the box cannot drift off it however you drag. The sizes below are what each platform serves at its largest; more pixels than that are spent on their transcoder rather than on the viewer.

RatioExport aroundUse it for
1:11080 × 1080Profile pictures, square feed posts, grid thumbnails, album art
4:51080 × 1350The tallest an Instagram or Facebook feed post can be — the most screen per scroll
9:161080 × 1920Stories, Reels, TikTok, Shorts — anything that fills a phone
16:91920 × 1080YouTube thumbnails, link cards on X and LinkedIn, slides, banners
3:21800 × 1200The 35mm frame. Prints at 6×4 inches with nothing trimmed off
4:31600 × 1200The phone and compact camera shape, and 8×6 inch prints

None of those the one you were given? Type the two numbers under Custom, or press ⇄ Turn to stand any lock on its side — 16:9 becomes 9:16 without hunting for a second chip.

Questions

Frequently asked questions

Is this free, and does the crop have a watermark?

Free — no watermark, no account, no limits.

Does my photo get uploaded anywhere?

No. Cropping runs in your browser; the file never leaves your device.

Will cropping make the picture blurry?

No. Crops keep original pixels unless you tick “Resize the crop”.

Can I crop to an exact size in pixels?

Yes — type left, top, width and height, or set an output width after cropping.

Can I crop a picture into a circle?

Yes. Pick Circle under Corners and save as PNG or WebP for transparency.

What image formats can I open and save?

Open JPG, PNG, WebP, GIF, AVIF or BMP. Save as PNG, JPG or WebP.

Can I straighten a tilted photo before cropping?

Yes — the straighten slider turns by 0.1°. Quarter turns and mirror are one click.

My phone photo is portrait — will it come out sideways?

No. EXIF orientation is applied so portrait photos stay upright.

Can I crop a picture on my phone?

Yes — drag the box with a finger the same way as with a mouse.
