Privacy and Limitations

JPG to PNG runs entirely in your browser. Files up to 25 MB are supported. Because JPG cannot store transparency, transparent output is only possible when the source itself contains alpha data — which a JPG never does.

If you need the file in another format, the PNG to JPG converter and JPG to WebP converter handle the reverse and WebP directions.

Frequently Asked Questions

How do I convert JPG to PNG?

Choose a .jpg or .jpeg file above and the conversion runs automatically in your browser. Preview the PNG, then download it.

Is JPG to PNG lossless?

PNG is a lossless format, so the converted file keeps every pixel from the decoded JPG without further compression loss. Note that the original JPG may already contain lossy compression from when it was saved.

Can a JPG be converted into a transparent PNG?

No. JPG has no alpha channel, so the source contains no transparency information to recover. Converting an opaque JPG produces an opaque PNG.

Will the PNG be larger than the JPG?

Usually yes. PNG is lossless and stores photos less efficiently than lossy JPG, so files are frequently larger — the trade-off for a lossless format.

Can I convert multiple JPG files at once?

Not yet. This tool converts one file at a time in your browser. Batch conversion would require a native app or server-side tool.

Are my JPG files uploaded?

No. The conversion runs locally in your browser and the file is never sent to Photo2URL.
