Higher quality creates a larger JPG file.
JPG has no transparency, so transparent pixels use this color.
How this tool works
PNG pixels are decoded and encoded as JPEG inside a disposable browser worker. Transparency is flattened because JPEG does not support an alpha channel.
- Choose one or more PNG images.
- Set JPEG quality and the color used behind transparent pixels.
- Process the queue, then download files individually or as a ZIP.
Processing stays inside a disposable browser worker. Canceling or leaving the page terminates that worker and releases its memory.
Capabilities and limits
- Files per job
- 1–50
- Per-file limit
- 50 MB
- Privacy mode
- LOCAL ONLY
- Images above 40 megapixels are rejected to reduce decompression-bomb and memory risk.
- JPEG is lossy, so very low quality settings can introduce visible artifacts.
- No server fallback is used when worker canvas encoding is unavailable.
