This converter turns JPEG images into PNG without uploading anything. JPEG compresses photographs well and opens on literally everything, but it cannot store transparency and softens fine detail and text. PNG stores every pixel exactly and supports full transparency, which is usually the trade you want when the image is destined for a website.
Converting to PNG is the right move when you need maximum compatibility — every browser, email client, and desktop application made in the last two decades opens PNG without complaint.
Transparency is preserved, so logos, icons, and cut-out product shots survive the conversion with their alpha channel intact.

Frequently asked questions
Are my images uploaded to a server?
No. The conversion runs inside your browser using WebAssembly, so the image data never leaves your device. That also means there is no queue, no account, and no file size cap imposed by a server.
Does converting JPEG to PNG reduce quality?
No. PNG is a lossless format, so every pixel is reproduced exactly as it was in the source file.
Is PNG supported everywhere?
Yes. PNG is about as universally supported as an image format gets.
Can I convert several images at once?
Yes. Drop in as many files as you like — or a whole folder — and they are processed in parallel across your CPU cores. When they finish you can download them individually or grab everything as a single ZIP.
