JPG to PNG Converter — Free Online
Need a transparent background? Convert your JPG to PNG. Need a smaller file? Go PNG to JPG. Both directions work. And everything happens in your browser — nothing gets uploaded.
JPG vs PNG: Which to Use
Quick rule of thumb: JPG for photos, PNG for everything else. JPG uses lossy compression — files are small but you lose a bit of quality. PNG uses lossless compression — quality stays perfect but files are bigger. Need a logo with transparency? PNG. Uploading vacation photos? JPG. This converter switches between them in seconds.
No Quality Loss on Conversion
One thing to know: converting JPG to PNG doesn't magically restore quality. The PNG is lossless going forward, but it can't get back what JPG already threw away. Like photocopying a photocopy, basically. Going PNG to JPG does introduce some quality loss — that's just how JPEG compression works. Play with the quality slider to find your sweet spot.
Frequently Asked Questions
Transparency. That's the main reason. PNG has an alpha channel, JPG doesn't. Plus PNG uses lossless compression, so no ugly artifacts around text and sharp edges. Need a logo with a see-through background? Screenshots? Images with text? PNG every time.
File size, plain and simple. A photo as PNG might be 5 MB. Same image as JPG? 500 KB. If you don't need transparency, JPG saves space and loads way faster on websites.
You can convert multiple images one at a time. Drop them in sequentially and download each converted file.
