Crop images to custom dimensions and aspect ratios

Tips for getting Image Cropper right
- Crop before resizing; shrinking first throws away pixels you might want later
- For social banners use the platform's published ratio (e.g. 16:9 for YouTube thumbnails at 1280×720)
- Keep the original file until you've inspected the crop edges at 100% zoom
Aspect-ratio quick reference
| Target | Ratio | Common output |
|---|---|---|
| Instagram square post | 1:1 | 1080×1080 |
| Instagram story / Reels cover | 9:16 | 1080×1920 |
| YouTube thumbnail | 16:9 | 1280×720 |
| LinkedIn banner | 4:1 | 1584×396 |
| Passport-style photo | approx 7:9 | varies by requirement |
Quality expectations
- Cropping is lossless for untouched regions but saving re-encodes as PNG/JPEG — JPEG re-saves at quality 90+ to avoid visible artifacts
- Repeated crop-and-save cycles compound generation loss; work from the original each time
- Transparency survives only in formats that support it (PNG, WebP) — JPEG fills transparent areas with white
Frequently Asked Questions
Can I crop to a specific aspect ratio?
Yes. The tool offers preset ratios like 1:1, 4:3, 16:9, and allows custom ratio input.
Can I undo the crop?
Yes. You can readjust the crop area before downloading. The original image is never modified.
What is the maximum image size?
There is no strict limit, but very large images may take slightly longer to process in the browser.
Privacy & Security
Cropping happens on a canvas in your browser. Images are never uploaded.
