Frequently Asked Questions

Frequently Asked Questions about JPG to PNG Converter

Will converting JPG to PNG improve image quality?

No. While PNG is lossless, it cannot reconstruct detail that was already lost during original JPEG compression.

PNG uses lossless compression which preserves every pixel exactly, requiring more storage than lossy JPEG compression.

Can I convert multiple JPGs at once?

Yes, Pixena supports batch conversion and allows one-click ZIP download of all converted PNGs.

Are my images uploaded to a server?

No. Conversions run locally on your device via HTML5 Canvas and WebAssembly.

Does this tool preserve EXIF metadata?

By default, Pixena strips unneeded metadata to reduce file size, but you can toggle metadata preservation.

Does Pixena work on iPhone and Android?

Yes, Pixena is fully responsive and executes client-side on mobile Safari, Chrome, and Firefox.
