Estimated memory
Your browser reports only a coarse memory hint, so this figure is an estimate.
| Device profile | Largest file | Largest image | Files per batch |
|---|---|---|---|
| Minimal | 40 MiB | 32 megapixels | 50 |
| Low | 75 MiB | 50 megapixels | 100 |
| Balanced | 150 MiB | 90 megapixels | 250 |
| High | 250 MiB | 150 megapixels | 500 |
Your browser is placed in one of these profiles from the coarse hints it exposes. A file above the limit is refused before it is read, rather than after the tab has run out of memory.
Limitations
- Lossy compression discards detail permanently. Re-compressing a file that was already compressed removes more detail without recovering anything an earlier pass removed.
- An animated GIF, WebP or AVIF is not handled by the still-image engine. It is refused rather than quietly reduced to its first frame.
- Transparency is flattened onto the matte colour before encoding. The alpha channel cannot be recovered from the result.
- This is a re-encode rather than a copy: whatever compression the source already carried is encoded again along with the picture.
