Convert PNG to JPG
PNG is the default for screenshots and graphics, but it's a heavyweight way to store a photograph. Converting to JPG routinely cuts a photographic PNG to a tenth of its size — which is why upload forms, listing sites, and email attachments so often demand it.
Open converterHow to convert PNG to JPG
- 1
Open your PNG
Drop the PNG into the converter above — JPG is already selected as the output format, so there's nothing to set up first.
- 2
Choose a quality level
Move the quality slider; 85 is a good default for photos. If the PNG has transparent areas, they'll be flattened onto a white background, because JPG can't store alpha.

Download the JPG
Click Convert & download to save the file. Got a folder of PNGs? The Batch tab converts them all in one go and hands you a ZIP.
Why convert PNG to JPG?
-
Photographic PNGs shrink dramatically — a 12 MB PNG photo typically lands between 1 and 2 MB as a JPG at quality 85.
-
Plenty of older systems only accept JPG: job portals, government forms, print kiosks, and CMS uploaders with strict whitelists.
-
Email and messaging size caps stop being a problem once the photo weighs a couple of megabytes instead of a couple dozen.
-
You set the quality level yourself with a live slider, so you decide the trade between size and detail.
What actually happens to your file
JPG has no alpha channel, so any transparent areas in your PNG are flattened onto a background color you choose before export — pixels can't be 'partly there' in a JPG. The encoder then compresses the image in 8×8 blocks, discarding detail your eye is least likely to miss. That's ideal for photos but visibly fuzzes hard edges, so screenshots of text or UI are usually better left as PNG. The conversion runs once, on your device, and your original file is never modified.
Frequently asked questions
What happens to transparent areas when I convert PNG to JPG?
JPG can't store transparency, so see-through pixels are filled with a solid background color — white by default, or any color you pick before exporting. If the transparency itself matters, convert to WebP instead, or keep the PNG.
What JPG quality setting should I use?
Quality 80–90 is the sweet spot for most photos: the file shrinks by 80% or more and the difference is hard to spot at normal viewing size. Drop below 70 only when file size matters more than close-up detail.
Should I convert screenshots from PNG to JPG?
Usually not. JPG compression blurs the sharp edges in text and interface elements, and a screenshot PNG is often already smaller than its JPG version would be. Convert screenshots only when an upload form refuses PNG.
