PNG→JPEG
Convert PNG to JPEG and get web-ready images that load fast and rank — built for bloggers, creators, and online sellers. Resize for social, optimize for SEO, and batch-process in your browser. No upload, no sign-up, no watermark.
Converted
Free, private, and genuinely simple
Most PNG to JPEG converters upload your images to a server you don't control, hide the real tool behind sign-up walls, or stamp watermarks on the result. This one does none of that. Everything happens in your browser, so it's faster and your images stay yours.
Completely private
Conversion runs on your device with the HTML5 Canvas API. Your PNG files are never uploaded, stored, or seen by anyone — including us.
Free forever
No account, no email, no premium tier, no watermark, and no daily cap. Convert one file or a hundred — it costs nothing.
Simple by design
Drop, convert, download. Adjust quality if you want, choose a background for transparency, and grab your files as a ZIP or individually.
Convert PNG to JPEG in four steps
Add your PNGs
Drag files onto the box above or click to browse. Add as many as you like.
Set quality
Pick a JPEG quality and a fill colour for any transparent areas.
Convert
Hit convert. Your browser does the work locally — nothing is uploaded.
Download
Save each JPEG separately, or download the whole batch as one ZIP.
Before you convert PNG to JPEG
A few things worth understanding so your results come out exactly as you expect.
JPEG can't keep transparency
PNG supports transparent backgrounds; JPEG does not. Transparent pixels are filled with a solid colour — white by default, or whatever you choose in the converter.
JPEG is lossy
JPEG discards some detail to shrink the file. At 90%+ quality the loss is invisible for most images, but repeatedly re-saving a JPEG will slowly degrade it.
Photos shrink dramatically
For photographs and detailed images, JPEG files are often 60–90% smaller than the equivalent PNG — ideal for web pages, email, and storage.
Keep PNG for graphics
Logos, screenshots, line art, and anything with sharp edges or text stays crisper as PNG. Convert to JPEG when the file is a photo or when size matters most.
Which format should you use?
| Property | PNG | JPEG |
|---|---|---|
| Compression | Lossless | Lossy |
| Transparency | Yes | No |
| Best for | Logos, graphics, screenshots | Photos, web images |
| File size (photos) | Large | Small |
| Sharp text & edges | Excellent | Softer |
| Universal support | Yes | Yes |
| Animation | APNG (rare) | No |
A short history of PNG and JPEG
JPEG is standardised
The Joint Photographic Experts Group publishes the JPEG standard. Its lossy compression makes photographic images small enough to store and share on the hardware of the era — a breakthrough for digital photography.
PNG is born
PNG (Portable Network Graphics) is created as a free, patent-unencumbered replacement for GIF after licensing disputes over GIF's LZW compression. It adds lossless compression and full alpha transparency, and becomes a W3C Recommendation in 1996.
The web splits the two
As the web grows, a practical convention forms: JPEG for photographs, PNG for logos, icons, and anything needing transparency or crisp edges. That division still holds today.
Both become universal
Every operating system, browser, camera, and app supports PNG and JPEG natively. Converting between them — usually PNG to JPEG to save space — becomes one of the most common everyday image tasks.
Interesting facts about PNG & JPEG
The name is a recursive joke
"PNG" is often said to stand for "PNG's Not GIF" — a nod to its origin as a GIF replacement, in the playful tradition of recursive acronyms used by programmers.
JPEG is a committee, not a format
JPEG literally names the group of experts who created it. The file format they defined is technically JFIF, but the world simply calls it JPEG.
.jpg and .jpeg are identical
The two extensions are the same format. Early Windows limited extensions to three letters, so .jpeg became .jpg — and both have coexisted ever since.
PNG has an alpha channel
Beyond simple on/off transparency, PNG supports 256 levels of partial transparency, which is why soft shadows and smooth edges look so clean.
JPEG can't do transparency at all
There is no transparent JPEG. That's why converting a transparent PNG to JPEG always needs a background colour to fill the empty pixels.
JPEG revolutionised the web
Without JPEG's compression, image-heavy websites would have been impractical on dial-up. It's one of the technologies that made the visual web possible.
