Free JPG to PNG Converter — No Upload Required
This tool converts JPEG images to PNG entirely inside your browser. Your files never leave your device — there's no server, no storage, and no account required.
PNG is a lossless format — meaning zero quality is lost in the conversion. It's ideal when you need a transparent background, crisp edges for logos, or pixel-perfect accuracy. The tradeoff is that PNG files are larger than JPEGs.
Why would I convert JPG to PNG?
PNG is lossless — no quality is lost. It's the better choice when you need transparency, sharp text, logos, or screenshots where every pixel needs to be exact.
Will my PNG be larger than the original JPG?
Almost always yes — that's completely normal. PNG stores every pixel without compression loss, so the file is larger. You're trading file size for perfect quality.
Is my image uploaded to a server?
No. Everything runs in your browser using JavaScript and the Canvas API. Your image never leaves your device, making this completely private.
Does JPG to PNG improve the image quality?
No — converting JPG to PNG won't recover quality that was already lost when the JPG was created. It simply re-packages the existing pixels in a lossless container.
Can I get a transparent background from my JPG?
Not with this tool — JPEGs have no transparency data to extract. To get a transparent background you'd need a background removal tool first, then save as PNG.
