PNG to JPG converter
PNG files are lossless, which makes them large. Converting to JPG typically cuts the size by 80–95% — worth doing for photographs and email attachments, though not for screenshots full of text.

Questions
Are my images uploaded anywhere?
No. Everything runs in your browser using the Canvas API — the file never leaves your machine, and the tool keeps working if you go offline after the page loads. There is no account, no queue, and no server-side copy to delete later.
Will converting to JPG lose quality?
JPG is a lossy format, so some data is discarded. At 90% quality the difference is invisible for screenshots and UI images. Drop to 70–80% only if file size matters more than crisp text — compression artefacts show up around lettering first.
My PNG had a transparent background. What happens to it?
JPG cannot store transparency, so transparent areas are filled with white. If you need to keep the alpha channel, convert to WebP instead.
