About JPG to PNG
Converting JPG to PNG does not recover quality the JPG already lost — no converter can — but it does stop any FURTHER loss. From the moment an image is PNG, every subsequent save, crop, and edit is lossless, which is exactly why editors and print workflows ask for it. It is the right move before repeated editing rounds, and the only move when a pipeline simply refuses JPG.
The conversion is a local, exact re-encode: your browser decodes the JPG and writes the pixels into a lossless PNG on your own machine. No upload, no account, no watermark; batches come back as a ZIP.
How it works
- Drop your JPG filesOne file or a batch.
- Local lossless re-encodeThe decoded pixels are stored exactly in PNG form — no further quality loss, ever.
- Download the PNGsEdit, re-save, and print without generation loss from here on.
When to use JPG to PNG
Before repeated editing
Every JPG re-save degrades the image a little more. Converting to PNG first freezes the quality where it is.
Pipelines that require PNG
App-store asset uploads, some CMSes, and print shops specify PNG.
Crisp UI mockups from photos
Compositing JPG photos into design tools that work PNG-native.
Frequently asked questions
Does converting to PNG improve the quality?
No — and any tool claiming it does is misleading you. JPG artifacts that already exist are preserved exactly. What PNG gives you is no FURTHER loss on every future save.
Why is the PNG so much bigger?
PNG stores the pixels losslessly; JPG compressed them aggressively. A 500 KB JPG can easily become a 3 MB PNG. That is the price of losslessness, not a bug.
Does the PNG get transparency?
The format supports it, but a JPG has no transparency to carry over — the PNG will have a fully opaque background. Use an editor to remove backgrounds afterwards if needed.
Is anything uploaded?
No. The conversion runs in your browser; your images stay on your device.
