What is a PNG to JPG converter?
A PNG to JPG converter re-encodes a PNG image as JPEG. PNG is a lossless format that stores every pixel exactly and can carry transparency, which is why it is the default for screenshots and design exports — and also why the same picture often weighs several megabytes. JPEG is the opposite trade: it compresses much harder, opens in every browser, editor and printer driver, and is the format most upload forms expect.
Conversion is the right move when the image is photographic and does not need an alpha channel — a photo exported from Photoshop, a scan, a phone shot or a full-screen screenshot. For those files JPEG typically cuts the size by 60–90% with no visible difference at normal viewing size.
It is the wrong move when the PNG depends on transparency (a logo, an icon, a cut-out), when the content is line art or small UI text that lossy compression softens, or when you plan to keep editing and re-saving the file. In those cases keep the PNG, or convert it to PNG to WebP if the goal is simply a smaller file that still supports alpha.
This converter runs entirely in your browser with the Canvas API. The PNG is decoded, its transparent pixels are composited onto white, and the result is written as JPEG at quality 85 — the file never leaves your device. If you need the reverse conversion, use the JPG to PNG converter.
How to convert PNG to JPG
- Drop your PNG files onto the upload area, or click to browse. The picker accepts several files at once, so a whole folder of screenshots can be queued in one step.
- Check the queue: each entry shows the file name and its original size before anything is converted.
- Conversion starts automatically after you select your images.
- Download and open a result to check any formerly transparent areas — JPEG fills them with white.
- Compare the original and converted sizes to confirm the result fits the limit you are targeting.
- Download the JPEGs individually, or use Download all to save the whole batch at once.
PNG to JPG examples
Four conversions you can reproduce with the tool above. The converter always writes JPEG at quality 85, so the output sizes below are typical results rather than exact guarantees.
Transparent logo
logo.png — 210 KB, 1024×1024, alpha channel
logo.jpg — 84 KB, transparent pixels composited onto white
Web screenshot
dashboard.png — 1.4 MB, 2560×1440
dashboard.jpg — 340 KB (76% smaller, text still legible)
Photo exported as PNG
portrait.png — 4.1 MB, 3000×2000
portrait.jpg — 1.1 MB (73% smaller, 85% quality)
Print asset
flyer.png — 8.2 MB, 3000×4000
flyer.jpg — 2.1 MB, ready for a photo print service
JPG vs PNG
| Dimension | JPG | PNG |
|---|---|---|
| Compression | Lossy, very small for photos | Lossless, large for photos |
| Transparency | Not supported | Supported |
| Text and sharp edges | Can show artifacts | Crisp |
| File size for photos | Typically 60–90% smaller | Baseline |
| Best for | Photographs | Diagrams, UI, logos |
Frequently asked questions
How do I convert PNG to JPG?
Drop the PNG files onto the upload area above and press Convert. Every file in the queue is re-encoded as JPEG at quality 85, and you can download the results individually or all at once.
What happens to transparent areas?
Transparent pixels are composited onto a white background, because JPEG has no alpha channel. If you need to keep transparency, keep the file as PNG or convert it to WebP instead.
Does converting PNG to JPG reduce quality?
Yes, JPEG is lossy. At quality 85 photos usually look identical on screen, but flat-colour graphics, small UI text and logos with sharp edges can pick up ringing and slight blur.
Why is my JPG smaller than the PNG?
PNG stores every pixel losslessly, so photos and screenshots stay large. JPEG discards detail the eye is unlikely to notice and typically cuts photo size by 60–90%.
Can I convert several PNG files at once?
Yes. The upload area accepts multiple files and the queue converts them in a single run, so a folder of PNGs becomes JPG in one batch.
Should I use PNG or JPG for screenshots?
Use PNG for screenshots of text, UI or charts, where crisp edges matter. Use JPG when the screenshot is mostly photographic and the file needs to be small.
Are my files uploaded?
No. Conversion happens in your browser with the Canvas API, so the images never leave your device.
PNG to JPG Tips
- JPG is far smaller than PNG for photos, screenshots and scans.
- Transparency is flattened to white, because JPG has no alpha channel.
- Quality is fixed at 85% — the level where photos look unchanged on screen.
- Keep PNG for logos, icons and line art, where lossy compression softens edges.
- Select several files at once: the queue converts a whole batch in one run.
