Convert PNG to JPG
PNG files can be huge. JPG makes them small and email-friendly. Convert here with a quality slider you control — and nothing leaves your browser.
PNG vs JPG: what changes
A PNG screenshot or export can easily be several megabytes — too big to email, slow to upload, and overkill when the image has no transparency to protect. JPG compresses the same picture down to a small, universally accepted file.
The one thing to know: JPG has no transparency, so any transparent areas in your PNG are flattened onto a solid background during conversion. For photos and opaque graphics that’s a non-issue and the size savings are dramatic. Use the quality slider to balance crispness against file size — it all happens locally, so you can re-try until it’s right.

Why convert in your browser
Nothing is uploaded
Every byte is decoded and re-encoded on your own machine using Canvas and WebAssembly. Your images never touch a server, so there is no upload bar, no queue, and no copy of your file sitting in someone else’s bucket.
Works offline
After the first load the converter is cached. Open it on a plane, on hotel Wi-Fi, or with the cable unplugged and it still runs at your CPU’s full speed.
Frequently asked questions
What happens to transparency when converting PNG to JPG?
JPG can’t store transparency, so transparent regions are filled with a solid background during conversion. If you need to keep transparency, convert to WebP or stay with PNG instead.
What quality setting should I use?
For most images, 85–92 looks indistinguishable from the original while making the file much smaller. Drop lower for aggressive compression, or push to 100 to maximise fidelity.
How much smaller will the JPG be?
Often dramatically — opaque PNGs frequently shrink by 70% or more as JPGs. The converter shows the exact resulting size for each file.
Is the conversion private?
Completely. It runs in your browser with no uploads, so your images never reach a server.
