Frequently asked questions

How do I resize an image without losing quality?

Shrinking keeps images sharp because pixels are only removed. Enlarging beyond the original size adds blur. Keep the aspect ratio locked and export PNG for graphics or JPG at 85%+ for photos.

Does resizing reduce file size?

Yes. Halving the width and height removes about 75% of the pixels, which usually cuts the file size by a similar amount. Combine it with the FileSlim compressor for the smallest possible result.

Will resizing blur-sm my image?

Scaling down uses high-quality smoothing and stays sharp. Scaling above the original resolution cannot invent detail, so enlarging beyond 100% will always look softer.

Are my photos uploaded anywhere?

No. The resize happens in your browser using the Canvas API. No file, thumbnail or filename is sent to a server.

Can I resize many images at once?

Yes. Add as many images as you like; each one is resized with the same settings and delivered as a ZIP archive.
