Frequently asked questions

Can I resize without losing quality?

You can export as PNG or use a high-quality JPG or WEBP setting. Resizing always changes the pixel dimensions, but the tool keeps the source sharpness.

Can I resize many images at once?

The first release processes one image at a time. Batch resizing is planned for a future version.

Does the resizer upload my image?

No. All resizing happens locally in your browser.
