Limitations & Compatibility
Frequently Asked Questions
Are my images uploaded to a server?
No. All resizing and compression happens locally in your browser using the HTML5 Canvas API. Your images never leave your device.
How does quality compression work?
When exporting as JPEG or WebP, the browser applies a compression algorithm. A quality of 80% usually reduces file size significantly with almost no visible loss in detail.
Is there a file size limit?
Because processing happens in your browser's memory, extremely large images (e.g. 50MB+) might cause the browser to freeze or crash on older devices. We recommend images under 25MB.
