FAQ
- Does this upload my image to a server?
- No. Resizing happens entirely in your browser using the Canvas API. Your image never leaves your device.
- Which format should I use?
- WebP produces the smallest files at equal quality — ideal for web use. JPEG is best for photos when broad compatibility matters. PNG is lossless and best for images with text, logos, or transparency.
- Will resizing reduce quality?
- Scaling down (making smaller) generally looks fine. Scaling up (making larger) will look blurry because the extra pixels are interpolated — no resizer can add detail that wasn't in the original.
