How to convert PNG to JPG

Drop your PNG file into the converter above, or click to browse. Nothing is uploaded — the file stays on your device.

Adjust the settings (quality and an optional max width). Tip: Quality 85 is ideal for screenshots — text stays crisp and the file typically shrinks by 80% or more. Transparent areas will be flattened (JPG has no alpha).

Click “Convert to JPG”. The conversion runs locally in your browser — larger files take longer, and a progress bar keeps you posted.

Why convert PNG to JPG?
PNG is lossless, which is wonderful for editing and terrible for sharing photos: a photographic PNG can be many megabytes where a visually identical JPG is a few hundred kilobytes. Converting is the quickest way to make screenshots and photos email- and upload-friendly.
JPG is also the safest format for forms and legacy systems that are picky about uploads — profile photos, applications, listing sites — where PNGs sometimes exceed size limits or get rejected.

About the formats
PNG Portable Network Graphics
PNG is the standard lossless image format: pixels are preserved exactly, and full alpha transparency is supported. That makes it ideal for screenshots, logos, and UI graphics — at the cost of much larger files than lossy formats, especially for photos.
JPG JPEG (Joint Photographic Experts Group)
JPG is the universal photo format. Its lossy compression shrinks photographs dramatically with little visible quality loss, and every device, website, and app on earth can open it. It doesn't support transparency, and re-saving repeatedly degrades quality.
Frequently asked questions
How much smaller will my file get?
For photos and screenshots, typically 70–90% smaller. The gain is biggest on photographic content; flat graphics with few colors compress well as PNG already and shrink less.
My PNG has a transparent background — what happens to it?
JPG can't store transparency, so transparent pixels are flattened to a solid background in the output. If transparency matters, convert to WebP instead, which is smaller than PNG and keeps the alpha channel.
Is this PNG to JPG converter really free?
Yes — completely free, with no watermarks, no sign-up, and no conversion limits. The tool is supported by ads on this page, so the converter itself never asks you for anything.
Are my files uploaded to a server?
No. This converter runs entirely in your browser using WebAssembly (a browser build of FFmpeg). Your PNG file never leaves your device — nothing is uploaded, stored, or seen by us, which also makes it safe for private or confidential files.
Is there a file size limit?
There's no hard limit. Because conversion happens on your own device, the practical ceiling is your browser's memory — files up to a few hundred megabytes work well on most computers. Very large files may be slow or fail on low-memory devices.
Why does the first conversion take a moment to start?
The first time you convert, your browser downloads the conversion engine (about 31 MB) once. It's cached after that, so later conversions start instantly — and they keep working even offline.
