Formats, file types, and size limits for Compress
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 |
Size limits
Each image can be up to 50 MB. There is no daily cap on how many images you can compress, and since processing runs locally, the practical limit is your device's memory.
How much smaller can it get?
The result depends on the format and content:
- JPEG photos compress especially well, often a large fraction smaller
- PNG files are lossless and larger to start; quality control trims them noticeably
- WebP is already compact, so savings are smaller
Getting the best results
- Photos with smooth areas compress more than busy, detailed images
- Preview to confirm the quality-to-size trade-off is worth it
- Keep the original so you can re-compress at a different level later
Verdict
Compress handles JPEG, PNG, and WebP up to 50 MB, with quality control and preview for predictable results.
