PNG to JPG Converter

PNG files are pixel-perfect but bulky — a single screenshot can hit 5 MB; a logo with transparency, 1 MB. JPG strips the alpha channel and uses lossy compression to land at a fraction of the size, with no visible quality loss for photos. Drop your PNG (or up to 30 of them) and get back JPGs in under five seconds. No signup, no watermark, full quality control.

When PNG to JPG is the right move

JPG wins anywhere file size matters and transparency doesn't. Web pages, email attachments, social uploads, image-heavy newsletters — all benefit from JPG's 5–10× size reduction over PNG for photographic content. Screenshots of UI, slides from presentations, and photos of physical things all qualify. PNG stays the right format for logos, icons, illustrations with transparent backgrounds, and any image that will be re-edited losslessly.

The conversion is one-way and lossy. The information PNG keeps that JPG drops — exact pixel values, alpha channel — won't come back if you ever convert the JPG back to PNG. Keep the original PNG somewhere if you might need to re-edit it later. For images you only need to display once, the JPG is fine to ship as your only copy.

How to convert PNG to JPG online

1. Drop the PNG file into the upload area above. Single file, multiple files, or a folder all work — we handle them the same way. Free tier accepts up to 30 files per batch; Premium handles 100.
2. Pick a quality level. The default of 85 is the web standard — visually identical to the source for any normal viewing. Drop to 60 for tiny thumbnails; bump to 95 for archival-grade output. Premium users can pick 100 (effectively lossless within the JPG format).
3. Choose a fill color for transparent areas. White is the default and matches most use cases (especially Amazon and e-commerce uploads). You can pick black, any HEX colour, or — if your PNG has no transparency to begin with — leave the setting alone.
4. Download. Single file goes back as the original name with `.jpg` extension; batches come back as a zip. Output preserves EXIF (date, GPS, camera info) by default — strip it via our EXIF Stripper if you're sharing publicly.

Quality, transparency, and what JPG can't do

JPG was designed in 1992 for photographic content and the codec's compression assumptions reflect that. It excels on continuous-tone imagery — photos, gradients, sky, skin — and stumbles on hard-edge content like text, line art, and pixel-art. If you're converting a PNG screenshot full of small text or a vector-style illustration, you'll often see the characteristic "ringing" artifacts around the edges. For those cases, stay with PNG (or convert to WebP, which compresses similarly to JPG but handles edges better).

Transparency is the other thing JPG can't preserve — the format has no alpha channel. Our converter fills transparent areas with whatever colour you pick. If you need to keep transparency, use the Transparent PNG Maker instead, or stay in PNG and just compress it losslessly.

How big is the size win, really?

The savings vary wildly with content. A 1920×1080 PNG screenshot with lots of solid colour might shrink 90% (5 MB → 500 KB). A photographic PNG of the same dimensions usually drops 70–80% (3 MB → 700 KB). A small icon-sized PNG might barely shrink at all because the compression overhead eats most of the gain. The free tier shows the size delta after each conversion so you can see what the trade-off looks like for your specific image.

For batch optimisation across mixed file types, our Batch Image Optimizer picks the best codec per image automatically — JPG for photos, lossless PNG for graphics, WebP if you've enabled it.
