PNG to JPG Converter
Shrink heavy PNG photos into JPG files that are small enough to email, upload and share, with a quality slider so you decide the trade-off.
Nothing is uploaded. Your photos are converted inside your own browser and never leave your device. No signup, no watermark, no limit on the number of files.
Higher keeps more detail and makes bigger files. 90% suits most photos.

Good to know
- Phone photos stay the right way up: the rotation stored in the file is applied before converting.
- JPG has no transparency, so converting to JPG fills transparent areas with white. PNG and WebP keep transparency.
- Converting re-encodes the picture, so camera metadata (EXIF: date, camera settings, GPS location) is not copied to the new file. That also means a converted photo no longer reveals where it was taken. To see what a photo carries first, open it in the EXIF viewer.
- Large photos, 48 MP and up, take a few seconds each. If a browser cannot hold one at full size, it is saved at the largest size that browser allows and labelled so in the list.
What PNG is good at
PNG compresses without losing anything and supports transparency. That makes it the right format for logos, graphics, screenshots and cut-out product shots on a transparent background. For an ordinary photograph it is wasteful: a photo saved as PNG is often several times the size of a high-quality JPG that looks the same.
When to convert PNG to JPG
Convert photos that ended up as PNG, from a screenshot tool, an export setting or a phone app, when they need to be emailed, uploaded to a site with a size limit, or delivered in a client gallery. Keep logos, text-heavy graphics and anything with a transparent background as PNG: JPG blurs sharp edges and cannot be transparent.
What changes in the JPG
The file gets much smaller and the compression becomes lossy; at 90% quality that loss is not visible on a photo. Transparent areas are filled with white. A 16-bit PNG is saved as an 8-bit JPG, and any metadata in the PNG is not copied.

Frequently asked questions
Why is my PNG photo so large?
PNG keeps every pixel exactly, and photographs have so much fine variation that lossless compression barely shrinks them. JPG discards detail the eye does not notice, which is why the same photo is far smaller as a JPG.
What happens to a transparent background?
JPG cannot store transparency, so transparent areas are filled with white. If the image has to stay transparent, keep it as PNG or convert it to WebP.
Should I convert screenshots and logos to JPG?
Usually not. JPG compression leaves visible fringes around text and hard edges, and those images are often smaller as PNG anyway. PNG to JPG pays off for photographs.
Which quality setting should I use?
90% is a good default for photos. Go to 80% for smaller web uploads, or 95 to 100% for prints and for files you will edit again.
