Domande frequenti
›Will resizing reduce quality?
Downscaling looks great. Upscaling is limited by the source — we use a high-quality bicubic algorithm but can't invent detail that isn't there.
›Are my images uploaded?
No — resizing happens entirely in your browser.
›Can I resize multiple images at once?
Currently one at a time. Batch processing is on the roadmap.
›Will it preserve transparency?
Yes — PNG and WebP keep their alpha channel. JPG output is always opaque.
›Is the resizer free?
Yes — fully free, no signup, no size limits.
