Drop a JPG and get a lossless PNG back instantly — no upload, no signup, no quality lost in the conversion. The honest version of this tool’s pitch: PNG won’t make a JPG better, but it will stop it getting worse.
How to convert JPG to PNG
- Drop your JPG in the box — conversion starts immediately.
- Preview the result and check the new size.
- Download your PNG.
What this conversion does — and honestly doesn’t — do
A JPG was compressed lossily the day it was saved: some fine detail is gone for good. Converting to PNG faithfully preserves everything that’s left, byte-for-byte lossless from this point on. What it cannot do is resurrect discarded detail or sharpen compression artifacts. If a converter promises “enhanced quality,” it’s selling you the placebo. What PNG genuinely buys you is protection from future loss.
The re-editing problem PNG solves
Every time a JPG is opened, edited, and saved as JPG again, it’s re-compressed — and the artifacts compound. Crop it Monday, adjust it Tuesday, annotate it Wednesday, and by Friday the sky is banding. Converting to PNG before an editing session means every intermediate save is perfect; you only take a compression hit once, at the final export. That’s the workflow professionals use, and it’s the best reason this tool exists. (Crop right here with the crop tool — it can output PNG directly.)
The other reason: systems that insist
Plenty of uploaders simply require PNG: app store assets, print-on-demand portals, government forms, CMS logo slots, documentation systems. The requirement is rarely about quality — it’s about predictable handling. Either way, arguing with a form validator is not a good use of an afternoon.
Details worth knowing
Expect the file to grow — often several-fold, because lossless photo storage is expensive (see the FAQ). The conversion won’t create transparency; JPGs don’t have any to preserve. Dimensions are untouched, and EXIF metadata (location, camera) is dropped, which is usually what you want when sharing. Going the other way for size reasons? That’s PNG to JPG.
Private by design
Decoding and re-encoding run in a background thread on your device. No server sees your photos — which is exactly how converting family pictures and ID scans should work.
