What this image cropper does
Drop a photo or screenshot and a crop box appears over it. Drag the box to move it, pull any of the eight handles to resize it, or type the exact width, height and position in pixels — the box and the numbers stay in sync both ways. A rule-of-thirds grid helps line up horizons and faces, and a live label shows the output size, so you know a 1080 × 1080 avatar really is 1080 × 1080 before you download it. The area you keep is copied pixel for pixel: cropping never rescales, so a 300-DPI scan stays 300 DPI.
Ratio presets lock the box to 1:1 for avatars and Instagram squares, 4:5 for Instagram portraits, 16:9 for YouTube thumbnails and slides, 9:16 for Stories and Reels, 4:3 and 3:2 for classic prints, or 'Original' to trim edges without changing the shape. With a ratio locked, dragging a corner keeps the proportion exactly, and the box shrinks rather than distorts when it reaches the edge of the image. Decoding, cutting and re-encoding all happen in your browser — no upload, no queue, no account, no watermark.
How to use it
Drag an image onto the drop zone, click it to browse, or paste a screenshot from the clipboard (Ctrl/Cmd+V works anywhere on the page). Pick a ratio if you need one, then adjust the box with the mouse, a finger on a touchscreen, or the arrow keys (1 pixel per press, 10 with Shift) while the box has focus. For a pixel-exact cut, type the width and height, then the X and Y offset from the top-left corner. 'Reset' returns the box to the largest area that fits the chosen ratio; 'Choose another image' swaps the picture but keeps your settings.
Choose the output format before clicking 'Crop'. 'Keep original' returns PNG as PNG and JPEG as JPEG; WebP gives the smallest file every modern browser displays; PNG is right when the crop contains text or a transparent background. The quality slider applies to JPEG and WebP only — PNG output is always lossless. The result appears below with its size and dimensions: download it, or hand it straight to the image compressor, the format converter, the resizer or image to PDF without re-selecting the file. Ratio, format and quality are remembered on this device.
Common pitfalls
Cropping removes pixels but never adds them: a 1:1 crop from a 4000 × 3000 photo is at most 3000 × 3000, and if you then need 1080 × 1080 the resizer is the second step. Re-encoding a JPEG always costs a little quality, so keep it at 90% or above for photos you will edit again, or output PNG as a lossless intermediate. Transparent areas survive in PNG or WebP output but are filled with white in JPEG, which has no alpha channel. Animated GIFs are flattened to their first frame. EXIF metadata — camera model, GPS position, orientation tag — is discarded on re-encode; if a phone photo appears sideways, it was relying on that tag, so rotate it in a photo app first.
Background: aspect ratios and the rule of thirds
The ratios in the preset list each come from a physical format. 3:2 is the 24 × 36 mm frame of 35 mm film, adopted by Leica cameras in the 1920s and inherited by most DSLRs and mirrorless cameras today. 4:3 is the shape of early television and of most phone and compact-camera sensors. 16:9 was standardised for HDTV in the 1990s and is now the default for monitors, YouTube and presentation slides; 9:16 is simply that frame turned upright for phone screens. The rule-of-thirds grid drawn inside the crop box goes back further still: the painter John Thomas Smith described the principle in 1797, suggesting that placing the horizon and the main subject on the lines a third of the way across a picture produces a more balanced composition than centring them.
Where cropped images are used
Profile pictures are the most common case: a square 1:1 crop that keeps the face away from the edges works on almost every service, and the resizer then brings it to the 400 or 800 pixels a platform asks for. Social posts need 4:5 or 9:16 crops so the feed does not letterbox or cut them; product photos are cropped to one consistent ratio so a shop grid lines up; screenshots are trimmed to the relevant window before going into a bug report or a slide; scanned pages lose their dark borders before being combined with image to PDF. Web designers crop hero images to the exact banner shape, then compress and convert to WebP. A cropped screenshot containing a code from the QR generator should be saved as PNG so the modules stay crisp.
Frequently asked questions
Is my image uploaded anywhere?
No. The image is decoded, cut and re-encoded inside your browser. You can disconnect from the network after the page loads and the tool keeps working.
Does cropping reduce quality?
The pixels you keep are copied unchanged, without scaling. The only loss comes from saving as JPEG or WebP; choose PNG output or keep the quality at 90% or above if you need a lossless or near-lossless result.
How do I crop to an exact size such as 1080 × 1080?
Choose the 1:1 ratio, then type 1080 into the width box; the height follows the ratio and the position can be nudged with the X/Y fields or the arrow keys. If the image is smaller than 1080 pixels, crop first and then enlarge with the resizer.
Can I crop several images at once?
No — cropping is a visual decision per image, so this tool works one image at a time. For batch operations that apply the same numbers to every file, use the resizer, converter or compressor, all of which accept many files.
Why does my phone photo appear rotated?
Phones often store the picture sideways and add an EXIF orientation tag; some browsers ignore that tag when decoding. Rotate the photo in your gallery app first, or crop as shown and rotate the result afterwards.
