Nothing is uploaded. Your files never leave this browser. You can even paste an image with Ctrl/Cmd+V.
Converting JPEG to PNG is a common task when you need lossless quality. JPEG and JPG are the same format; only the file extension differs. Older Windows software wanted three-letter extensions, so '.jpg' became common, while '.jpeg' is the original spelling. Both open identically everywhere. PNG, on the other hand, gives you lossless quality and transparency (alpha) support. ZeroUpload performs this conversion entirely inside your browser, so your JPEG file is never uploaded to a server.

When should you convert JPEG to PNG?
You should convert JPEG to PNG when you want logos and brand assets that need a transparent background but your source is JPEG. Typical situations include renaming or normalising photo extensions, satisfying software that expects one specific spelling, where the destination expects PNG instead.

Strengths
- + Lossless quality
- + Transparency (alpha) support
- + Great for sharp edges and text
Trade-offs
- – Larger files than JPG for photos
- – No animation
