Convert PNG to JPG
Convert PNG to JPG to shrink photo files fast. Batches run up to 10 files, 20MB each. Your files stay on your device the whole time.
Photographs benefit the most from this conversion. A camera photo saved as PNG stores every pixel, which balloons the file size fast. JPG's lossy compression handles that same photographic detail far more efficiently, so the resulting file often shrinks a lot while still looking close to the original.

PNG vs JPG
PNG
PNG is the lossless choice, ideal for screenshots, logos, and sharp edged graphics with flat color. It stores photographic detail far less efficiently, so photo files run large.
JPG
JPG trades some fidelity for a genuinely small file, encoding photos at quality 92 here. Screenshots and logos pick up visible artifacts under that same compression though.
Why convert PNG to JPG
Photographs are the one place this conversion clearly wins. A camera photo saved as PNG stores every pixel uncompressed, while JPG's lossy algorithm was built specifically for that kind of photographic detail and gradient, so the size drop can be dramatic. What it costs: transparency disappears completely, since JPG carries no alpha channel, so any see-through area in the PNG becomes a solid color instead. Flat colored graphics suffer too. Screenshots, logos, and text pick up visible blocky artifacts under JPG compression, because the format assumes photographic noise, not clean sharp lines. A simple rule covers both cases: convert photos, keep screenshots and logos in PNG. If the image needs its transparent background kept, this is the wrong page entirely, no conversion setting brings transparency back once it is gone.
JPG shrinks photographs far more than PNG ever can.
Transparency is lost. Screenshots, logos and line art can show visible artifacts.
Private by design
Both files stay on your device, nothing is uploaded to a server.
FAQ
Will the file get smaller?
Usually yes, and often by a lot for photographs. JPG's lossy compression handles photographic detail far more efficiently than PNG's lossless approach.
What happens to transparency?
It is lost. JPG has no alpha channel, so any transparent area in the PNG becomes a solid background instead.
Should I convert screenshots and logos too?
Generally no. Flat colors, text, and sharp edges pick up visible artifacts under JPG compression. Keep screenshots, logos, and line art in PNG and save this converter for photos.
The JPG result is still too big for a portal's limit, now what?
That is not a failed conversion. Every portal sets its own cap, and a highly detailed photo needs a larger file to still look right. Check the result size before assuming something went wrong.
