or — multiple files welcome. Nothing is uploaded; conversion happens on your device.
Files are processed entirely in your browser — never uploaded, never stored. Large photos convert in about a second each; the first HEIC file loads a small decoder module.
How it works
Converting JPG to PNG does not restore lost quality — it freezes the image so nothing further degrades. That matters before repeated editing, and for the many forms and systems that simply require a .png file.

- No quality decision needed — PNG stores the pixels exactly as decoded.

JPG vs PNG
| JPG | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| Re-editing | Degrades each save | Never degrades |
| File size | Small | 5–10× larger for photos |
| Best for | Final delivery | Working copies, requirements for PNG |
Tip: Editing a photo repeatedly? Convert to PNG once, do all edits there, and export to JPG a single time at the end — one generation of loss instead of many.
Frequently asked questions
Does converting JPG to PNG improve quality?
No — compression artifacts already baked into the JPG stay. PNG just stops any further loss, which is useful before editing an image repeatedly or when a form demands PNG.
Why is the PNG so much larger than my JPG?
PNG is lossless and JPG is heavily compressed, so 5–10× growth is normal for photos. That’s the price of a format that never degrades.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using its built-in image engine — files never leave your device, which also makes it faster than upload-based converters and safe for private photos.
