The online image cropper supports:
- JPG — the most common photo format
- PNG — lossless quality, supports transparency
- WebP — modern format with excellent compression
Output is always saved as a high-quality PNG to preserve maximum detail.

Most online crop tools are either free with watermarks or require a subscription. BurnMyPic is 100% free with no watermarks, no signup, and no limits. You can crop 1,000 images in a row and it will never ask you to pay or register.
Frequently Asked Questions
Does cropping reduce image quality?
Cropping itself doesn't reduce quality — it just removes pixels outside the selected area. The remaining pixels are untouched at full resolution.
Can I crop on mobile?
Yes! The tool is fully responsive and works on iPhone, iPad, and Android devices in any mobile browser.
What's the maximum file size?
Files up to 10MB are supported. For larger files, compress your image first, then crop.
