Frequently Asked Questions

How do I make a JPG background transparent when converting to PNG?

Simply tick the "Make White Background Transparent" checkbox above before converting. Our browser engine scans every pixel and converts solid white or off-white backgrounds into true alpha transparency, giving you a clean cut-out PNG ready for Canva, Photoshop, or website headers.

Can I bulk convert multiple JPGs to PNG at once?

Yes! Unlike cloud converters that cap you at 5 files, our tool processes everything using your own device's browser memory. You can convert dozens of JPG images at once and download them in a single ZIP folder.

Why is the converted PNG file size sometimes larger than the JPG?

Because PNG is a lossless image format that supports alpha transparency and crisp edges without compression blur, the resulting file retains maximum visual detail.
