Features

🎚️

Set AVIF quality from 1 to 100 to balance file size against visual detail.

💾

Smaller Files

AVIF compresses photographs more efficiently than JPEG, often at noticeably smaller sizes.

🔎

Modern Format

AVIF is a next-generation image format supported by all modern browsers.

🔒

Private by Default

Conversion runs entirely in your browser. Your images are never uploaded or seen by any server.

How to Use the JPG to AVIF Converter

  1. Drag and drop a JPG into the upload area, or click browse files to select one from your device.
  2. Move the AVIF quality slider to choose the trade-off between file size and detail.
  3. Check the preview and the before and after file sizes.
  4. Click Download AVIF to save the converted file, or click Reset to start over.

Privacy and Client-Side Security

Privacy Guarantee: All conversion occurs locally inside your browser. Your files and data are never transmitted, stored, or recorded on remote servers.

Many online converters ask you to upload your image before processing. That creates privacy risk for personal or work files. TinyToolzz takes a different approach: the JPG to AVIF conversion happens entirely on your device with the HTML5 Canvas API and a local WebAssembly encoder that loads in your browser.

The preview and the final AVIF file are both produced in your browser memory. Nothing is sent over the network, stored, logged, or shared. When you leave the page or click Reset, the image data is released from memory.

Frequently Asked Questions

Why should I convert a JPG to AVIF?
AVIF is a next-generation image format that typically compresses photographs more efficiently than JPEG. That means the same visual quality at a smaller file size, which helps pages load faster and uses less storage.
Will the JPG to AVIF conversion make my file smaller?
Usually yes, but the exact result depends on the image content and the quality setting you choose. AVIF is generally more efficient than JPEG, so most photos come out noticeably smaller at a similar quality. The tool shows the before and after size so you can compare.
Is converting JPG to AVIF lossy?
Yes. Your JPG was already lossy when it was created, and the AVIF encode is also lossy, so some additional detail is discarded and cannot be recovered. Keep the quality slider high if the original detail matters, and avoid converting the same image repeatedly.
Which browsers can convert JPG to AVIF?
All modern browsers can convert JPG to AVIF with this tool. Chromium-based browsers such as Chrome 122 and Edge 122 encode AVIF natively through the Canvas API. In Firefox, Safari, and older browsers, the tool loads a local WebAssembly AVIF encoder on first use, so you get the same result on any device without any server upload.
Can everyone view an AVIF file?
AVIF viewing is supported in Chrome 85 or newer, Edge 121 or newer, Firefox 93 or newer, and Safari 16.4 or newer. Some older software and some social media platforms still do not display AVIF, so keep that in mind before converting files meant for those places.
Are my JPG files uploaded to a server when I convert them?
No. The JPG to AVIF tool runs entirely in your browser using the HTML5 Canvas API. Your image is read from your device, converted locally, and is never transmitted, stored, or recorded on any remote server.
