When JPG to PNG conversion makes sense
The main reason to convert JPG to PNG is when you need to do further editing without accumulating compression artifacts. Every time you save a JPG, it re-compresses and loses a tiny bit of quality. Converting to PNG first gives you a lossless working copy that won't degrade with repeated saves.
It's also useful when you need to add transparency to an image — JPG doesn't support it, but once converted to PNG, you can add transparent regions in any image editor.
Important: this doesn't improve quality
Converting a JPG to PNG preserves the current quality but doesn't restore detail that was already lost to JPG compression. If your JPG has visible compression artifacts, those artifacts will be preserved exactly in the PNG output. Think of it as "locking in" the current quality rather than improving it.

Frequently Asked Questions
Yes — free to use with no limits. Convert as many JPG files to PNG as you need, no account or payment required.
Usually yes — PNG files are typically 3–5× larger than JPG for the same image. That's the trade-off for lossless quality. If file size matters more than pixel perfection, JPG or WebP may be better choices.
No. The conversion runs entirely in your browser using the Canvas API. Your images are processed locally in memory — no network requests involved.
Yes. Drop as many JPG files as you need and they'll all be converted. Each gets its own download link.
Yes — that's one of PNG's key advantages over JPG. However, converting a JPG to PNG won't add transparency since the original JPG doesn't have any. The conversion preserves the existing image content in a lossless format.
