## How to convert JPEG to PNM

3. **Convert.** Click Convert. Your files are converted right in your browser in seconds.
4. **Download your PNM.** Download each PNM file, or everything at once as a ZIP.

## Good to know

- Converting to PNM won't restore detail that JPEG compression already removed, but it prevents any further quality loss when you edit and re-save.
- JPEG files are typically used for digital camera output, photo libraries and web images, while PNM is best for image processing pipelines.
- This conversion runs on libvips, running locally in your browser — nothing is uploaded and it works even on slow connections.

**JPEG:** JPEG is the same format as JPG with a longer extension. It uses lossy compression tuned for photographs and is readable by virtually every device.

**PNM:** PNM is the umbrella name for the Netpbm PBM, PGM and PPM formats.
