## About

JPG to AVIF re-encodes ordinary JPG photos into AVIF, the modern format that delivers the same visual quality at a fraction of the file size — commonly 30–50% smaller. Smaller images mean faster page loads, better Core Web Vitals, cheaper data, and snappier uploads. The conversion runs server-side with a real AVIF encoder, so the output is a genuine AVIF file rather than a renamed copy.

## Key features

- Real AVIF encoding server-side — not a renamed file
- Typically 30–50% smaller than JPG at matching quality
- Adjustable quality for size-versus-fidelity control
- Ideal for web performance and Core Web Vitals work
- Free with no signup; server-side processing

## How to use

1. **Upload the JPG** — Drop the photo or image you want to optimize.
2. **Convert** — The encoder produces an AVIF at your chosen quality.
3. **Download the AVIF** — Use it on modern websites and enjoy the smaller file.

Yes — the AVIF to JPG tool reverses the conversion at any time. Keep your original JPG if you may need it.
