Frequently Asked Questions
How to convert JPG to PNG online?
Upload your JPG file to our free online converter. The tool processes your image entirely in your browser using the Canvas API — no server upload needed. Click convert and download your PNG instantly.
Does PNG support transparency?
Yes. PNG supports alpha channel transparency, which means you can have fully or partially transparent backgrounds. This is one of the main reasons to convert from JPG to PNG.
Will the converted file be larger than the original JPG?
Typically yes, because PNG uses lossless compression. A JPG file might be 200KB while the same image as PNG could be 1-3MB. The trade-off is that PNG preserves every pixel of quality without any artifacts.
Is my image data kept private during conversion?
Yes. All conversion happens locally in your browser using the Canvas API. Your images are never uploaded to any server, ensuring complete privacy. Close the tab and everything is gone.
When should I convert JPG to PNG?
