Crop Images Online — Free & Preset Ratios

Cropping an image here is a four-step loop: drop the file, pick a ratio, drag the selection box into place, and download. The tool accepts JPG, PNG, and WebP files up to 50 MB and crops inside your browser with the Canvas API, so the file never leaves your device and the result is ready the moment you click Crop. Cropping removes pixels but does not re-encode the part you keep, so the visible area stays exactly as sharp as the original. To make it concrete: a 4000x3000 photo cropped to a 1:1 square drops from 4000x3000 to 3000x3000, and the file typically falls from 3.5 MB to under 2 MB without touching the image quality.

1. 1Drop or select an image. JPG, PNG, and WebP files up to 50 MB are accepted.
2. 2Pick a ratio from the presets (1:1, 4:3, 3:2, 16:9, 9:16 and the vertical versions) or leave it free-form.
3. 3Drag the box to move it and drag the corner handle to resize it.
4. 4Click Crop and download. Your original file is never modified.

• 1:1 for profile pictures, avatars, and product listings.
• 4:3 and 3:2 for standard photos and slides.
• 16:9 for YouTube thumbnails, hero banners, and video covers.
• 9:16 for Instagram Stories, TikTok, and Reels, with 3:4 and 2:3 available for portrait feeds.

No. Cropping removes pixels around the outside and keeps the remaining area untouched, so the part you keep is not degraded or re-encoded at a lower quality. The output format follows the source, so a JPG stays a JPG and a PNG keeps its transparency. The quality slider lets you set the encode level for JPG and WebP sources; it is hidden for PNG, where the encode stays lossless. If the cropped area is a small fraction of the original, the file can stay large relative to its new dimensions, which is when you would follow up with the resizer to get a properly sized result.

Preset ratios are the right choice when a platform requires an exact aspect, because you drag the box and the proportions lock themselves. Free-form is for when no specific ratio matters and you want to trim exactly what is in the frame. Both modes share the same drag controls: drag inside the box to move it, and drag the corner handle to resize it. As you drag the corner handle, the box keeps the selected ratio, and the label above it shows the real pixel dimensions of the crop.

Cropping removes pixels, so the file almost always gets smaller, but not by as much as resizing the same area would. A 4000x3000 photo cropped to a 3000x3000 square keeps three quarters of the pixels, so the file lands around three quarters of its original weight. If you then resize that square to 1080x1080 for upload, the file drops far more, because you are discarding pixels rather than just trimming the frame. The exact drop depends on how much of the frame you keep, which is why the preview shows the output dimensions before you download.

Every crop is performed locally with the Canvas API inside your browser. Nothing uploads, no account is required, and your original file is never changed; the tool creates a new cropped file for download. That makes the tool a sensible choice for sensitive material such as ID scans, client assets, or personal photos that you would rather not hand to a third-party service.
