Crop Image
Crop a JPG, PNG or WebP right in your browser — drag the selection with corner handles or type exact X, Y, width and height in pixels. Nothing is uploaded.
Drag the box to move it, drag a corner to resize — or use the pixel fields below. Keyboard: focus the box, arrows nudge 1 px, Shift+arrows resize.
Cropped result
Load a JPG, PNG or WebP on the left — the cropped result appears here live, with a Download button. One image at a time.
Your image never leaves your device. Decoding, cropping and re-encoding all happen in this tab with the Canvas API — no uploads and no server. Disconnect from the internet and it still works.
Two ways to place a crop — and why the numbers matter
A crop is just four numbers: X and Y (how far the selection's top-left corner sits from the image's top-left corner, in pixels) and Width and Height (how many pixels to keep). The draggable rectangle and the numeric fields are two views of the same four numbers, kept in sync both ways: drag the box and the fields update; type in a field and the box moves. The fields alone can do everything the mouse can — which is the only way to hit an exact crop like x 500, y 0, 3000 × 3000 reliably. For the last pixel, focus the box and use the arrow keys (move 1 px) or Shift+arrows (resize 1 px).
Every value is clamped so the selection can never leave the image: on a 4000×3000 photo, a 500-wide crop can sit at X 0 through X 3500 and no further, and the selection can never shrink below 1×1 px. Type something out of range and the tool pulls it back to the nearest legal value instead of failing.
What the aspect presets are for
An aspect preset locks the selection's shape while you move and resize it. Clicking one also places the largest crop of that shape, centered — on a 4000×3000 photo, 1:1 gives a 3000×3000 square starting at x 500, and 16:9 gives 4000×2250 starting at y 375. The common uses:
| Preset | Shape | Typical use |
|---|---|---|
| 1:1 | Square | Profile pictures, Instagram posts |
| 4:3 | Classic | Phone and compact-camera photos, iPads |
| 3:2 | Photo | DSLR/mirrorless sensors, 6×4″ prints |
| 16:9 | Widescreen | YouTube thumbnails, presentation slides |
| 9:16 | Vertical | Stories, Reels, TikTok, phone wallpapers |
With a lock active, editing Width recomputes Height (and vice versa), and corner drags keep the ratio while the opposite corner stays anchored. Free removes the lock without moving your selection.
Cropping is lossless — re-encoding is where quality lives
Unlike resizing, cropping invents no pixels and interpolates nothing: the pixels inside the rectangle are copied out unchanged. Quality only enters when the result is saved. PNG output is lossless — a crop saved as PNG is pixel-identical to the source region. JPEG and WebP re-compress at the slider's quality, exactly like re-saving in any editor; one pass at 0.90 is visually transparent for photos. "Keep original format" writes a JPEG crop back out as JPEG, a PNG as PNG. One honest nuance: this tool re-encodes the whole crop rather than doing byte-level JPEG block surgery, so a JPEG→JPEG crop is not bit-identical to the source blocks — if you need forensic-grade lossless JPEG cropping (only possible at 8- or 16-pixel block boundaries anyway), you need a specialist tool like jpegtran.
Honest limits
One image at a time — this version has no batch mode; if you need the same rectangle cut from many files, that is a different workflow this tool doesn't pretend to cover. HEIC/HEIF is not supported, because browsers cannot decode Apple's HEIC — convert iPhone photos to JPEG first (Settings → Camera → Formats → Most Compatible). The EXIF orientation tag is honoured during decode, so sideways phone photos appear and crop upright, but the saved crop carries no metadata at all: the canvas strips EXIF, GPS and camera settings (usually a privacy win). Wide-gamut photos are treated as sRGB, and animated GIFs are flattened to their first frame. If you want to shrink the file rather than cut it, the image resizer and image compressor are built for that.
