How it works
- Drop your JPG files here, or select them from a folder.
- Each JPG is decoded and re-encoded as PNG — right in your browser.
- No quality setting needed: PNG output is always lossless from here on.
- Download the PNGs individually, or as one ZIP file.
A lot of upload forms — print-on-demand sites, some marketplaces, certain design tools — simply require PNG, even for a plain photo that started life as JPG (JPEG). It's worth knowing upfront: converting JPG to PNG does not improve image quality and does not add transparency. Whatever detail the JPG's compression already discarded stays discarded; PNG just stores that same result losslessly from this point forward, which is why the file gets larger, not better. This tool handles the conversion entirely in your browser, so the file never has to leave your device to satisfy someone else's upload requirement.
Why use convert.pics?
- No upload: the conversion runs locally, so the JPG never needs to reach a server.
- Satisfies any tool or form that specifically requires a .png file.
- Batch conversion for a whole folder of photos at once.
- No account, no watermark, no daily limit.
Frequently asked questions
Does converting JPG to PNG improve the image quality?
No. Any detail the JPG's compression already discarded is gone for good — PNG can't bring it back. Converting just stores the JPG's existing pixels losslessly from that point on; it doesn't undo prior compression.
Does JPG to PNG give the image a transparent background?
No. A JPG has no transparency information to begin with, so there's nothing to carry over — the PNG will be just as fully opaque as the source JPG was.
Why is the PNG file so much bigger than the JPG?
PNG stores every pixel losslessly, with no photographic compression, while JPG is specifically built to shrink photos by discarding detail the eye barely notices. Converting from JPG to PNG can easily triple or quadruple the file size for the same image.
Should I use PNG for photos?
Generally no — JPG is smaller and looks just as good for photographic content in almost every real-world use. PNG earns its keep for screenshots, logos, line art, and anything needing transparency or perfectly sharp edges.
