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

The entire process takes seconds on both Apple Silicon and Intel Macs, with no file data ever leaving your machine.
How the AVIF to JPG Mac Converter Works
When you load an AVIF file on your Mac, the converter leverages your browser's built-in AV1 image decoder — the same technology Safari, Chrome, and Firefox use to render AVIF images on websites. Here is what happens during the conversion.
- File Validation: The converter verifies your file is a valid AVIF image under 20 MB. Invalid files or oversized uploads are rejected with a clear error message before processing starts.
- AV1 Decoding on macOS: Your Mac browser's AV1 decoder extracts the compressed pixel data from the AVIF container. On Apple Silicon Macs, this may leverage hardware-accelerated media engines for faster decoding.
- Canvas Pixel Rendering: The decoded RGB pixels are painted onto an HTML5 Canvas at the original resolution. Transparent areas receive a white background fill because JPG does not support alpha channels.
- JPEG Compression: The Canvas API encodes the bitmap into JPEG format at 92% quality — optimized for the balance between file size and visual fidelity that macOS users expect for photography and design work.
- Local File Save: The resulting JPG is generated as an in-memory blob. Clicking Download triggers macOS's native save dialog, placing the file wherever you choose in Finder.
AVIF Input → AV1 Decode (Safari/Chrome/Firefox) → Canvas Bitmap → JPEG Encode (92%) → JPG Download via Finder Your images never leave your Mac. No iCloud upload, no server processing, no third-party access — everything stays inside your browser's local sandbox.
