Formats, file types, and size limits for Resize
A quick reference for what the tool accepts.
Supported formats
The tool works with common image formats.
| Format | MIME type | Status |
|---|---|---|
| JPEG | `image/jpeg` | Supported |
| PNG | `image/png` | Supported |
| WebP | `image/webp` | Supported |
| GIF | `image/gif` | Supported |
| AVIF | `image/avif` | Supported |
Size limits
Each image can be up to 50 MB. There is no daily cap on how many images you can resize, and since processing runs locally, the practical limit is your device's memory.
How you resize
Choose either method:
- Custom dimensions — set an exact width and height in pixels
- Percentage scale — enlarge or shrink by a percentage of the original
Getting the best results
- Use maintain aspect ratio to keep the image from being distorted
- Shrink by percentage for quick reductions; use exact dimensions for precise layouts
- Keep a copy of the original in case you need another size later
Verdict
Resize handles JPEG, PNG, WebP, GIF, and AVIF up to 50 MB, with both exact and percentage sizing.
