This free PNG to JPG converter runs entirely in your browser. Your images are never uploaded — conversion happens locally with the Canvas API, so even large or sensitive files stay on your device. There's no sign-up, no watermark, and no file-count limit.
Convert a single screenshot or a whole folder at once. Set exact output dimensions (with optional aspect-ratio lock), dial in JPG quality, choose a background color to flatten transparency, or target a maximum file size and let Pixelpaper auto-tune quality to fit. JPG is ideal when you want smaller files for email, web pages, or uploads where PNG's lossless size is overkill.
Frequently asked questions
Is it free?
Yes — completely free, no account, no watermark, no per-file limits.
Are my files uploaded?
No. Everything is processed in your browser. Your images never touch a server.
Can I batch convert?
Yes. Drop multiple images (or a whole folder), convert the batch, then download each file or all of them at once.
Will quality drop?
You control it. Use the quality slider, or set a target max file size and we auto-tune quality (and downscale if needed) to hit it.
