What Is AVIF & What Is JPG?
Two formats, two eras — here's what sets them apart.
AV1 Image File Format
AVIF is a modern, royalty-free image format built on the AV1 codec. It delivers up to 50% smaller files than JPEG with HDR support, transparency, and wide color gamut — but only works in newer browsers.
Key Strengths
- 50% smaller files at the same visual quality
- HDR and wide color gamut support
- Backed by Google, Apple, Mozilla & Netflix
Joint Photographic Experts Group
JPG is the world's most universal image format, standardized in 1992. It uses lossy DCT compression to keep photo files small and is natively supported by every browser, OS, camera, printer, and platform in existence.
Key Strengths
- Works on every device and platform ever made
- Ideal for photos, email, and printing
- Accepted everywhere — social media, CMS, e-commerce

How the AVIF to JPG Windows Converter Works
When you load an AVIF file on a Windows browser, the converter uses your browser's native AV1 decoder — the same codec engine that Chrome and Edge use to display AVIF images on websites. Here is exactly what happens under the hood.
- File Validation: The converter checks that your file is a valid .avif image and does not exceed the 20 MB size limit before processing begins.
- AV1 Decoding: Your Windows browser decodes the AVIF file's compressed AV1 intra-frame data into raw pixel values (RGB bitmap). This uses the same hardware-accelerated AV1 decoder built into Chrome, Edge, and Firefox on Windows.
- Canvas Rendering: The decoded pixels are drawn onto an HTML5 Canvas element at the exact original resolution. A white background fill is applied first to handle any AVIF alpha transparency, since JPG does not support transparent pixels.
- JPEG Encoding: The Canvas API's
toBlob()method re-encodes the pixel data into a standard JPEG binary at 92% quality — balancing small file size with visually lossless output. - Local Download: The resulting JPG blob is made available through an in-memory Object URL. When you click Download, the file saves directly to your Windows file system without any network transfer.
AVIF Input → AV1 Decode (browser-native) → Canvas RGB Bitmap → JPEG Encode (92% quality) → JPG Output Because all processing runs inside your browser's sandbox, your images stay on your Windows machine and are never transmitted over the internet.
