À propos de cet outil
Cropping cuts an image down to a rectangular area and discards everything outside it. Unlike resizing, it costs no quality at all: the pixels you keep are the original pixels, untouched. What cropping changes is composition and aspect ratio, which is usually the real reason people need it. A profile picture has to be square, a video thumbnail 16:9, a printed photo 4:3 or 3:2 - and a phone camera produces none of those by default. If you upload the wrong shape, the platform crops it for you, badly, usually cutting off someone's head. Cropping deliberately means you decide what survives. This tool offers fixed ratios for the common cases and a free mode for anything else, with the selection rendered live so you can see the result before committing. Everything happens in your browser and no image is uploaded.

Comment utiliser cet outil
- Add your imageDrop it in or browse to select. The full image appears with a draggable crop selection over it.
- Pick an aspect ratioChoose 1:1, 16:9, 4:3 and similar presets to constrain the selection, or free mode to crop any rectangle.
- Position the selectionDrag the box and pull its handles until the framing is right. What is inside the box is what you keep.
- Crop and downloadThe selected area is exported at its original pixel quality. Your source file is unchanged.
Pourquoi l’utiliser
- Lossless - the pixels you keep are exactly the pixels you started with.
- Fixed ratio presets for profile pictures, thumbnails and print sizes, so you avoid the platform cropping for you.
- Live preview, so framing is a decision rather than a guess.
- Runs on your device, so personal photos are never uploaded.
- No account, no watermark and no limit.
Usages courants
- Making a square profile picture from a normal photo without the platform cutting it awkwardly.
- Framing a 16:9 thumbnail for a video from a wider or taller source image.
- Removing unwanted objects, people or clutter at the edge of a shot.
- Straightening up a scanned document or receipt by cutting away the surrounding desk.
- Preparing product photos at a consistent ratio so a listing looks uniform.
Conseils pour de meilleurs résultats
- Crop before resizing. Cropping first means the resize works from exactly the area you are keeping.
- Leave a little space around the subject. Very tight crops give you no room if a platform trims further.
- For profile pictures, check how the image looks as a circle - most platforms mask square uploads into circles.
- Cropping heavily reduces the pixel count, so a small crop of a small image may end up too low-resolution to use.
- Keep the original. Cropping is destructive in the sense that the discarded area is gone from the exported file.
Erreurs à éviter
- Cropping to the exact display size, leaving nothing for a platform to work with when it crops again.
- Ignoring aspect ratio, then having the upload cropped automatically in a way that cuts off the subject.
- Cropping deeply into an already small image and ending up with something too soft to use.
- Cropping before straightening a photo, which means doing it twice.
- Overwriting the original file with the crop and losing the surrounding area permanently.

Questions fréquentes
Add your image above, choose an aspect ratio or free mode, drag the selection box to frame what you want, then crop and download. The area inside the box is exported at full original quality.
Yes. No account, no limit and no watermark on the cropped image.
No. The pixels you keep are unchanged - cropping only removes the area outside your selection. What does drop is the total pixel count, so a heavy crop leaves a smaller image.
Yes. Pick a fixed ratio and the selection is constrained to that shape as you drag, which is the reliable way to produce a square profile picture or a 16:9 thumbnail.
No. Cropping happens in your browser using its own canvas, so the image never reaches a server.
1:1 - square. Most platforms then mask it into a circle for display, so keep the subject centred and avoid placing anything important near the corners.
Crop them one at a time using the same fixed ratio preset, which keeps the shape consistent. For social platform sizes specifically, the Logo Resize Kit exports every required size in one pass.
Cropping removes part of the image and keeps the rest at full quality. Resizing keeps the whole image but changes how many pixels it has. They are often used together - crop for composition, then resize for the target dimensions.
