Frequently asked questions
- Is my image uploaded to a server?
- No. Resizing happens in your browser. Your file never leaves your device.
- Will it stay sharp?
- We use Lanczos resampling (pica) — the same high-quality method desktop editors use — so resized images stay crisp.
- Can I keep the aspect ratio?
- Yes. Lock the ratio to avoid stretching, or unlock it to resize to an exact width and height.
- What formats are supported?
- JPEG, PNG and WebP. PNG transparency is preserved; other formats output as JPEG.
