Crop Image

Drop a photo, drag the crop box to the area you want (or pick an aspect ratio preset), and download the result. Everything runs locally in your browser — nothing is ever uploaded.

What This Tool Does

Drop in a photo, drag a rectangle over the part you want to keep, and download the result. The crop box can be resized freely or snapped to one of four common aspect ratios, and the download is an exact pixel-for-pixel copy of whatever the box covers — no upload, no processing queue, just a rectangle you drag and a file you get back.

Aspect Ratio Presets

PresetShapeTypical use
FreeAny rectangle you dragCropping to an unusual or specific shape
1:1SquareProfile pictures, social media grid posts
4:3Classic photo/print ratioStandard prints, older screens
16:9WidescreenVideo thumbnails, banners, presentation slides
3:2Classic camera ratioDSLR and mirrorless photo prints

Choosing a preset locks the crop box's proportions while you drag its edges or corners — the box resizes but keeps its shape. Switch back to Free at any time to drag an arbitrary rectangle again.

Dragging the Crop Box

The crop box appears centered over your photo as soon as it loads, covering most of the image so you can see it immediately. Drag anywhere inside it to move it, or drag one of the eight handles on its edges and corners to resize it — corner handles resize both dimensions at once, edge handles resize just one side. Everything outside the box is dimmed so the selected area is always obvious. The Reset button puts the box back to its starting position and size at any point.

An Exact Pixel Crop, Not an Approximation

Tip: Cropping doesn't touch a single pixel inside your selection — it removes everything outside it and keeps the rest exactly as it was. There's no blurring, no resampling, and no quality slider to worry about for PNG, WebP, GIF, or BMP files. The only place a small re-compression step happens is when the source is a JPEG, since writing a JPEG always involves its own lossy encoding step — even the original file went through it once.

Because the crop is computed from the image's real pixel data — not from a screenshot of what's on screen — the downloaded file always matches your selection exactly, at full source resolution. If you drag the box over roughly a third of a 4000×3000 photo, you get back a crisp crop at that same native pixel density, not a soft, upscaled version of it.

Your Original Format Stays, EXIF Metadata Doesn't

Cropping changes an image's dimensions, not its container format — a cropped JPEG comes back as a JPEG, a cropped PNG as a PNG, and the same for WebP, GIF, and BMP. What doesn't survive is the file's EXIF metadata block: producing the new, smaller file means re-encoding it, and that process leaves camera model, timestamp, and any embedded GPS coordinates behind rather than carrying them into the crop. If you specifically need to check or strip that metadata, use the EXIF Metadata Viewer & Remover on the original file.

Your Files Never Leave Your Device

The moment you drop a photo, its bytes stay local to your browser tab. Dragging the crop box is rendered by your browser directly, and the final download is produced by a small WebAssembly module that never sends anything over the network. Closing the tab discards everything — there's nothing left behind on a server, because no server was ever involved.

If you also want to rotate or straighten this photo, add a watermark, or convert it to a different format, see the Rotate & Flip, Add Watermark, and Image Format Converter tools — all built the same on-device way.

Frequently asked questions

Is this crop tool really free?
Yes. There's no sign-up, no watermark added to your photo, and no limit on how many images you can crop. The tool runs entirely in your browser, so there's no server cost to recoup from you.
Do my photos get uploaded anywhere?
No. Dragging the crop box happens locally in your browser, and the final crop is produced by WebAssembly running inside the same tab. Your file never travels over the network.
Does cropping reduce image quality?
The crop itself is lossless — it's a direct copy of the pixels inside your selected rectangle, nothing is resampled or blended. If your source is a JPEG, the cropped result still has to be re-encoded to stay a JPEG, and that re-encode uses a fixed, high quality setting so any loss stays effectively invisible. PNG, WebP, GIF, and BMP crops have no lossy step at all.
What aspect ratios can I choose?
Free (drag any rectangle you like), plus four presets: 1:1 for a square, 4:3, 16:9 for widescreen, and 3:2. Picking a preset locks the crop box to that ratio while you drag; switching back to Free unlocks it.
Is EXIF metadata kept after cropping?
No. Producing the cropped file re-encodes the image, and that re-encode step drops the original EXIF block — camera details, timestamps, GPS coordinates, all of it. If you need to keep that data, crop a copy and keep the original file as well.
What file format do I get back?
Whatever format you dropped in. A JPEG stays a JPEG, a PNG stays a PNG, and the same holds for WebP, GIF, and BMP — this tool only changes the image's dimensions, never its container format.
Can I crop several photos in one batch?
This tool works on one photo at a time, so you can drag the crop box precisely and preview it before downloading. Drop your next photo once you've downloaded the first.
