About this tool
JPG to PNG Converter
You usually convert to JPG to save space — but sometimes you need to go the other way. Maybe you’re about to edit a photo and don’t want every save to chip away at the quality. Maybe a design tool or upload form insists on PNG. Maybe you need a transparency channel JPG can’t provide. Whatever the reason, this converter turns JPG into lossless PNG instantly, right in your browser, with nothing uploaded.
What converting to PNG does — and doesn’t — do
Be clear-eyed about this: it can’t restore quality JPG already threw away. JPG is lossy, so the artifacts baked in are permanent. What PNG buys you is a clean slate going forward — a lossless container where:
- Edits don’t compound damage — re-saving a PNG never adds new compression artifacts the way re-saving a JPG does.
- Transparency becomes possible — PNG has an alpha channel for any masking or layering you add later.
- Tools cooperate — many graphics and UI pipelines expect PNG and treat it as the canonical lossless raster.
Private and local
The conversion is 100% in-browser. Your device decodes each JPG and re-encodes it as a PNG; no file is uploaded, stored, or logged. Batch jobs work the same way — drop a folder’s worth of JPGs and get them back as a zip, all without a server.
Tips
- Convert before editing, not after — start your edits from the PNG so you don’t keep re-compressing a JPG.
- Expect larger files — lossless PNG is bigger. That’s the trade for an edit-safe copy.
- Need it small instead? JPG to AVIF gives you a much tinier modern file.
