Supported formats and limitations
Accepted formats are checked from file contents. Native browser codec support is required. Only still images are supported.
- Input formats
- JPGJPEG
- Output formats
- PNG
- PNG is often larger than the original JPEG and does not recover lost detail or create transparency.
- Embedded metadata is discarded. The browser applies supported image orientation and color handling.
The PNG download uses lossless encoding after JPEG decoding and keeps the oriented dimensions. It cannot reconstruct detail missing from the JPEG or make its background transparent. There is no PNG quality slider. Use Image Resize if you also need different dimensions.
Limits: 16 MiB per file, 8192px per edge, 8 megapixels. Batch input is limited to 8 files / 32 MiB, and retained batch outputs to 64 MiB. Metadata is discarded; color profiles and HDR may change.
