Why convert PNG to JPG?
PNG is lossless, which is great for graphics but wasteful for photographs. A photo exported as PNG can be three to five times larger than the same image as JPG, with no visible benefit. Converting photographic PNGs to JPG can dramatically reduce file size for email, web pages and storage.
Handle transparency before you convert
JPG cannot store transparency. When you convert a PNG that has transparent areas, those areas must be filled with a solid color. If your tool ignores this, you may get unexpected black backgrounds. A good converter lets you pick the fill color — white is the safe default for most layouts.
Converting step by step
With a browser-based converter the process takes seconds:
- Drop your PNG onto the tool.
- Select JPG as the output format.
- Choose a background color if the image has transparency.
- Set quality (85–90% is a good default), then download.
Everything stays local
Because conversion uses the browser's Canvas API, your PNG never leaves your device. There's no upload, no queue and no copy on a remote server. For screenshots that might contain sensitive information, that privacy is the whole point.
Summary
Converting PNG to JPG is the right move for photos that don't need transparency. Just decide on a background fill for any transparent areas, pick a sensible quality, and export — all without uploading a thing.
