How it works
- 100% Client-Side Privacy
- Zero server uploads. Images are decoded and converted locally using your browser's HTML5 Canvas and ImageBitmap APIs, keeping sensitive files strictly on your device.
- High-Speed Batch Processing
- Drag and drop multiple AVIF photos simultaneously. Parallel client-side processing handles whole collections with zero wait time.
- Flexible Output Formats & Quality
- Choose between JPG for universal compatibility with custom compression levels (50% to 100%), or PNG for lossless reproduction with alpha transparency.
- Instant ZIP Export
- Download converted images individually or batch export everything into a neat ZIP archive with automatic scroll guidance upon completion.
ConvertAVIF is a lightweight, privacy-first web utility built to eliminate image compatibility issues without compromising personal data.
Many modern phones and cameras export high-efficiency .avif files that older image editors, email clients, document tools, and websites cannot open. ConvertAVIF converts them into ready-to-share JPG or pixel-perfect PNG in seconds—entirely within your browser’s local memory.
