Convert JPG to PNG
Turn JPEG photos into PNG files, for example when an editor, upload form or print workflow only accepts PNG. Convert many files at once and download them together.
How to convert JPG to PNG
- Choose or drop your JPG files (up to 100).
- Click Convert to PNG.
- Download each PNG, or all of them as a ZIP.
Supported formats
- Input
- JPG, JPEG
- Output
- PNG
- Maximum size
- 50 MB per file (limited by your device's memory)
Benefits
- Every pixel of the JPG is kept exactly — PNG adds no further compression loss.
- Files are checked by their real content, so mislabelled files are caught before conversion.
- Batch conversion with a single ZIP download.
Limitations
- Converting cannot remove JPEG artefacts or add transparency; the PNG looks identical to the JPG.
- PNG files of photos are typically 2–5 times larger than the original JPG.
Privacy and security
Images are decoded and re-encoded by your browser in a background Web Worker (or on the page itself in browsers without OffscreenCanvas). Files are never uploaded, and the results exist only in this tab's memory until you download them.

Frequently asked questions
Will converting to PNG improve quality?
No. The PNG is a lossless copy of the JPG as it is, including any compression artefacts. It only prevents further loss when you edit and save the image again.
Why is the PNG so much bigger?
JPG uses lossy compression designed for photos, while PNG stores every pixel exactly. For photos that means much larger files. If size matters, consider WebP instead with the JPG to WebP tool.
Does the PNG get a transparent background?
No. JPG has no transparency, so the PNG has the same solid background. Removing a background requires an editing tool.
