How to crop an image
- Drop a photo onto the box above. It is decoded by your browser and never leaves your device.
- Drag inside the highlighted rectangle to move the crop, or drag any of the eight handles to resize it. The dimmed area is what gets discarded.
- Pick an aspect ratio if you need a fixed shape. With a ratio locked, every handle keeps the proportions for you.
- For an exact result, type the numbers straight into X, Y, Width and Height — they are in original image pixels and stay in sync with the box.
- Check the live preview on the right, then press Crop image and download.
Cropping with the keyboard
Tab until the crop box has focus, then:
| Keys | Action |
|---|---|
| Arrow keys | Move the selection by 1 px |
| Shift + arrows | Move the selection by 20 px |
| Alt + arrows | Resize from the bottom-right corner by 1 px |
| Alt + Shift + arrows | Resize by 20 px |
Does cropping lose quality?
The pixels you keep are copied verbatim — there is no scaling, no interpolation and no resampling, so the cropped region is bit-identical to the same region of the original. The only place quality can be lost is the final encode. If the source was a JPEG and you export a JPEG, the image is compressed a second time; at quality 90+ that generation loss is invisible, and exporting PNG avoids it entirely at the cost of a larger file.
Which aspect ratio to use
| Ratio | Where it is used | Typical pixels |
|---|---|---|
| 1:1 | Profile pictures, Instagram squares, product tiles | 1080 × 1080 |
| 4:3 | Compact cameras, iPad screens, many phone screenshots | 1600 × 1200 |
| 3:2 | DSLR and mirrorless sensors, 6 × 4 inch prints | 1800 × 1200 |
| 16:9 | Video thumbnails, slide decks, TV and monitor wallpapers | 1920 × 1080 |
| 9:16 | Stories, Reels, TikTok, phone lock screens | 1080 × 1920 |
| 2:3 | Pinterest pins, portrait prints | 1000 × 1500 |
| 1.91:1 | Open Graph and Twitter card previews | 1200 × 630 |
Composition tips that actually help
- The grid inside the crop box marks the rule-of-thirds lines. Placing a horizon or a subject’s eyes near one of them usually reads better than dead centre.
- Crop for the smallest place the image will be seen. A detail that is obvious on a laptop can vanish in a 48 px avatar.
- Leave a little headroom above faces, and avoid cropping through joints — wrists, ankles and elbows — which looks abrupt.
- If you need both a square and a wide version, crop the wide one first and re-crop the square from the original rather than from the already-cropped file.
Need a round profile picture instead? Use circle crop. Need to change the pixel dimensions rather than the framing? That is resize image.
Questions
Does cropping reduce quality?
Cropping itself removes pixels but never resamples the ones it keeps, so the remaining area is pixel-identical to the original. If the output is a JPEG it is re-compressed once; keep the quality slider at 90 or above, or export PNG, to make that step lossless in practice.
How do I crop to an exact size?
Type the numbers into the Width and Height boxes. They are in original-image pixels, and the X/Y boxes set the top-left corner of the selection, so you can hit an exact 1200 × 630 crop for an Open Graph image without guessing.
Can I crop without a mouse?
Yes. Tab to the crop box, then arrow keys nudge it one pixel, Shift + arrows move it 20 pixels, and Alt + arrows resize it. The numeric X/Y/W/H fields work with a keyboard too and stay in sync with the drag handles.
What aspect ratio should I choose?
1:1 for profile pictures and Instagram squares, 16:9 for video thumbnails and slides, 9:16 for stories and Reels, 3:2 for prints from most cameras, and 4:3 for older sensors and many phone screenshots.
