Frequently Asked Questions

Can I keep the aspect ratio?

Yes — enable “Keep aspect ratio” and the other dimension is calculated automatically.

Will resizing reduce quality?

Downscaling uses high-quality smoothing; enlarging a lot can soften details — use the upscaler for bigger enlargements.

Is it free and private?

Yes. It's completely free with no signup, and your image is processed in your browser — nothing is uploaded.
