How to Convert PNG to JPG?
Nothing is uploaded. The png file is decoded and re-encoded as jpg inside this tab.
Add your PNG files
Drag them in or use Choose Files. Batches are fine.
JPG is already selected
Keep quality at 85 or above. Below that, JPG's block artifacts start showing up around text and hard edges.
Convert and download
Everything runs locally, so the jpg file saves straight to your device.
Why Convert PNG to JPG?
PNG files from screenshots, design exports, or icons can be 3 to 10x larger than the equivalent JPG. If the image has no transparent areas, converting to JPG at 85% quality gives 60 to 80% file size reduction with no visible difference, ideal for email attachments and faster page loads.
About PNG
PNG uses lossless compression, making it the standard for design assets, UI screenshots, logos, and icons, especially those with transparency. PNG files are larger than JPG or WebP for photographic content.
About JPG
JPG's lossy compression makes it the most efficient format for photographs and complex imagery. JPG files are widely supported everywhere and are the standard format required by many CMSs, social platforms, and email clients.
What Happens to Transparency
This is the one thing to watch on this conversion. JPG has no alpha channel, so every transparent pixel is flattened onto a white background before encoding. A logo with a transparent background comes back as a logo sitting on a white rectangle. If you need that transparency preserved, convert to WebP or keep the PNG.
File Size: What to Expect
Screenshots and design exports usually shrink by 60 to 80%. A 1.8 MB PNG screenshot commonly lands between 250 and 450 KB as a JPG at 85% quality, with no difference visible at normal viewing size.
When Not to Convert PNG to JPG
Avoid JPG for screenshots containing small text, flat-colour interface elements, or line art. JPG's 8x8 block transform produces visible ringing around hard edges, which is exactly what text and UI are made of. PNG and WebP handle that content far better.
How the Conversion Works
The PNG is decoded, composited onto a white canvas to discard the alpha channel, then encoded with the browser's JPEG coder at your quality setting. 85 to 90% is the usual sweet spot between file size and visible artifacts.

When should I not convert PNG to JPG?
Avoid JPG for screenshots containing small text, flat-colour interface elements, or line art. JPG's 8x8 block transform produces visible ringing around hard edges, which is exactly what text and UI are made of. PNG and WebP handle that content far better.
What happens to my transparent background?
It becomes solid white. JPG cannot store transparency, so the converter flattens the image onto white first. Compositing onto white rather than black avoids the dark halos that naive conversion produces.
Why does text look fuzzy after converting to JPG?
JPG compresses in 8x8 pixel blocks, which smears the hard edges text is made of. Raise the quality slider above 90, or use PNG or WebP for text-heavy images.
Are my PNG images uploaded to a server?
No. The conversion runs entirely in your browser. Your PNG files never leave your device and are never sent anywhere.
