About the JPG to AVIF Converter
This JPG to AVIF converter turns photos from JPG into AVIF without installing software or uploading anything. It solves a common problem: JPG has no transparency and loses a little quality every time it is saved. Converting to AVIF gives you the smallest next-generation web images, ideal for the smallest possible website images and Core Web Vitals optimisation.
The converter decodes your JPG with your browser's own image engine and writes the AVIF with a small open-source AVIF encoder, so quality settings are applied precisely. Because everything happens on your own device, your photos are never uploaded, stored or seen by anyone else, which makes it safe for ID photos, Aadhaar or PAN scans and personal pictures.
What to expect: AVIF is compressed, and the quality slider lets you trade file size against detail; camera metadata such as GPS location is removed because the image is re-encoded.
How to use the JPG to AVIF Converter
- Click "Choose files" or drag your JPG photos onto the box. You can add several at once.
- Adjust the AVIF quality slider (85 is a good default) and, if you like, set a maximum width to resize.
- Press "Convert to AVIF". The conversion runs on your device and shows its progress.
- Download each AVIF file, or use "Download all (ZIP)" when you converted several.
- Open the result in Chrome or Edge to check it; your original JPG is never changed.
Tips & benchmarks
- AVIF encoding is slower than JPG; a quality of 50–65 already looks excellent and gives tiny files.
- Password-protected (encrypted) archives cannot be converted; extract them with the password first.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the AVIF to a website or government portal.

What is a JPG file?
JPG (JPEG) is the most widely used photo format in the world, standardised in 1992. It shrinks photographs dramatically by discarding detail the eye barely notices, but it has no transparency and loses a little quality every time it is re-saved.
What is a AVIF file?
AVIF is a royalty-free image format built on the AV1 video codec and released in 2019. It is often 30–50% smaller than JPG at the same visual quality and supports transparency and HDR, making it the most efficient image format browsers support today.
