PNG to JPG Converter
Convert PNG to JPG in your browser: watch transparent backgrounds flatten onto white and photo-like files shrink, with real size numbers before download.

PNG carries a fourth channel — alpha — that marks which pixels are see-through. JPG has no such channel. When you convert, every transparent and semi-transparent pixel gets blended onto a solid backdrop before encoding, usually white. The merge is permanent: once the file is saved as JPG, the original transparency information is gone and cannot be restored by converting back.
Where the conversion pays off is photographic content. A camera shot saved as PNG keeps every detail losslessly and can easily run several megabytes; the same pixels re-encoded as JPG at quality 80–90 look visually identical at a fraction of the size. The result panel shows both file sizes side by side, so you can judge the trade yourself.
Some images should stay PNG. Logos, icons and interface mockups rely on transparency to sit on arbitrary backgrounds; flattening them onto white boxes is rarely what you want. Dark-mode screenshots, line art and text renderings depend on PNG's exact pixels — JPG compression leaves a soft haze around sharp edges that no quality setting fully removes.
Common uses
- Getting a portrait into a government portal, exam signup or visa system that rejects anything but JPG — convert the PNG you received from the photo studio, confirm the dimensions still fit, and download the accepted file.
- Shrinking phone screenshots and camera captures saved as PNG so they fit an email attachment limit — photo-like pictures re-encode to JPG dramatically smaller while staying perfectly readable.
- Preparing a folder of PNG photos for a shared album, digital frame or car display that only reads JPG files — one quick conversion per image and the whole collection plays everywhere.
- Trading the lossless weight of PNG exports for faster page loads — when a design mockup's photographs ship to production as JPG, pages shed megabytes without a visible difference.
Frequently asked questions
- Why did my background turn white after converting?
- Because JPEG cannot store transparency, the conversion blends every see-through pixel onto a solid backdrop — white by default — before encoding. That merge is permanent inside the downloaded file; to keep holes and cutouts, the image has to stay PNG.
- Does converting PNG to JPG make the quality worse?
- On photographs, usually not visibly — JPEG drops detail your eye mostly ignores. Around sharp edges, flat colors and text you will see haze and color bleed instead. And any transparency is simply gone, which no quality setting can undo.
- Can I convert back to PNG to get transparency back?
- No. Saving a JPG back to PNG only puts the flattened pixels into a bigger lossless wrapper — the alpha channel is not recreated, so the white backdrop stays. Treat the conversion as one-way: the transparency data is discarded at encoding time.
- How much smaller will my PNG get?
- Photo-like images usually drop to a quarter or less of the PNG size at quality 80–90. Flat-color graphics may barely shrink and can even grow — JPEG is built for continuous-tone photography, and the panel's size comparison tells you the exact figure.
- Why do upload forms and signup systems ask for JPG?
- JPG is the oldest common denominator: every camera, phone and browser produces and opens it, and reviewers need no special software. Systems handling millions of uploads standardize on one predictable format — and JPG's small size keeps their storage bills down.
