Why Convert JPG to PNG?

Some forms, government portals, and legacy software accept PNG but block JPG uploads.

PNG stores decoded pixels without additional JPEG loss—useful when you need a stable intermediate for editing or screenshots.

HeicSave converts locally in your browser; your files never upload to our servers.

Frequently Asked Questions

Is JPG to PNG lossless?

PNG is lossless relative to the decoded JPG pixels. It cannot restore detail already lost in the original JPEG compression.

Will PNG files be larger?

Usually yes. PNG is best when you need compatibility or a lossless container, not minimum file size.

Batch convert JPG to PNG?

Yes. Add many files, convert once, and download a ZIP.

Do you upload my JPG files?

No. Conversion is client-side only.

Works offline?

After the page loads, conversion can run without sending your images online.
