JPG to PNG
Turn a JPG image into a PNG — instantly, privately, in your browser.
Your image is processed entirely in your browser — it is never uploaded to a server.
About this tool
The conversion is a re-encode: your browser decodes the JPG and writes a fresh PNG at full size and high quality (92%). Nothing is resized or cropped. The PNG will usually be larger than the JPG — PNG is lossless, JPG is not.
People convert JPG to PNG when a tool demands PNG, or to stop further quality loss in repeated editing. Be aware of what it cannot do: detail the JPG already threw away does not come back. The PNG is a faithful copy of the JPG, not an upgrade of it.
How to use it
- Choose a JPG image.
- Press Convert to PNG and save the result.
Frequently asked questions
Is my image uploaded?
No. The conversion runs in JavaScript in your browser; the file never leaves your device.
Does converting lose quality?
Converting to PNG or WebP (lossless mode off) — PNG is fully lossless. JPG and WebP re-encode with a small quality cost at the 92% setting, invisible in normal use. Converting between lossy formats repeatedly does add up, so keep your original.
Which browsers does this work in?
Any modern browser. Decoding depends on the browser supporting the source format — all current Chrome, Edge, Firefox and Safari versions handle WebP and AVIF.
