How to convert PNG to JPG
- Choose or drop your PNG files — a single image or a whole folder's worth.
- Set the quality (92% by default) and, if your PNGs have transparent parts, the color that should fill them.
- Press Convert to JPG and download the results. The list shows each file's size before and after.
When PNG to JPG pays off: photos
PNG never throws detail away, which makes it a poor container for photographs: every leaf, grain of sand and bit of sensor noise has to be stored exactly. Photos end up as PNG more often than you'd think — exported from editors, saved from design tools, produced by AI image generators, or captured as screenshots of a photo. Converting them to JPG is the single biggest size saving you can make. In our test (Edge, October 2026) a 3,840 × 2,400 landscape photo stored as PNG took 7.8 MB. As JPG it was 659 KB at 92% — about 12 times smaller and indistinguishable on screen — and 373 KB at 80%. That is the difference between an email attachment that bounces and one that arrives.
When to keep PNG: screenshots, text and logos
JPG compression is built for smooth photographic detail. On sharp edges — text, user interfaces, line art, charts — it leaves faint halos and blotches, and it often doesn't even save space. We converted a 1,351 × 3,433 full-page screenshot of a web page: the PNG was 271 KB, while the JPG was 477 KB at 92% and still 337 KB at 80% — bigger than the PNG, and blurrier. Keep screenshots, logos and diagrams as PNG (or try the image compressor), and convert only what is really a photo.
What happens to transparency
PNG supports transparent and semi-transparent pixels; JPG doesn't. The converter puts your background color underneath and blends soft edges into it, the same as placing the image on a sheet of that color. White is the default because documents and forms are usually white. For a logo that will sit on a colored banner, choose that banner's color so the anti-aliased edges blend in instead of showing a pale outline.
Picking a quality
- 90–95%: no visible difference from the PNG; use it for prints and images you may edit again.
- 80–85%: a good default for the web and email; differences show only when you zoom in.
- Below 70%: only when a strict size limit forces it — for a limit in KB, Reduce Image Size in KB finds the setting for you.
Private by design
Your PNGs are converted by your own browser and never uploaded, so screenshots of bank pages or documents stay on your device. The JPG files are freshly encoded and carry no hidden metadata. Going the other way? Use JPG to PNG, or the image converter for WebP.
Frequently asked questions
Will converting PNG to JPG reduce the quality?
Slightly: JPG is lossy. At 90–95% the difference is invisible in normal viewing; lower settings give smaller files with more visible artifacts, especially around text and sharp edges.
Why is my JPG bigger than the PNG?
Screenshots, text and flat-color graphics compress very well as PNG and badly as JPG. In our test a 271 KB screenshot PNG became a 477 KB JPG at 92%. Keep such images as PNG.
What happens to a transparent background?
JPG has no transparency, so transparent areas are filled with the background color you pick — white by default.
Can I convert several PNG files at once?
Yes. Select or drop as many PNG files as you like; each gets its own JPG download.
Are my files uploaded?
No. The conversion runs in your browser on your device; nothing is sent to a server.
