What is JPG?
JPG is a compact, lossy format designed mainly for photographs. Each JPEG encoding can discard subtle detail, which helps reduce file size but may leave visible artifacts around sharp edges.
What is PNG?
PNG uses lossless compression, supports transparency, and keeps newly encoded pixels exact. It is commonly used for graphics, screenshots, UI assets, and files that will undergo more editing.
When should I convert JPG to PNG?
- An application or workflow specifically requires PNG.
- You want to avoid another lossy save during later edits.
- You need a dependable browser format for graphics or documentation.
Keep in mind: Converting JPG to PNG does not restore detail previously removed by JPEG compression, and it does not invent transparency. The PNG is often larger than the original JPG.
JPG vs PNG
| Feature | JPG | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | Not supported | Supported by the format |
| Typical file size | Smaller for photos | Often larger for photos |
| Repeated editing | Quality can degrade | No new encoding loss |
Frequently asked questions
Will JPG to PNG improve image quality?
No. It prevents a new lossy PNG encoding step, but cannot recover information already discarded by JPG.
Will the output become transparent?
No. The format supports transparency, but ordinary JPG pixels remain opaque after conversion.
Why did the file get larger?
PNG stores pixels losslessly, which is less space-efficient for many photographs.
Where is my image processed?
Inside your browser, using a Web Worker and WebAssembly codecs.
