Need help?How to Convert JPG to AVIF Online
- Upload Your JPG Files — Drag and drop or select one or more JPG, JPEG, or JFIF images.
- Choose a Quality Preset — Select from Highest, Very High (Recommended), High, Medium, Low, Very Low, or Lowest. "Very High" is the default and balances quality with file size reduction.
- Adjust Resolution (Optional) — Keep original, reduce by percentage (1–100%), pick a preset (4320p down to 144p), or enter exact width and/or height in pixels or percent.
- Convert & Download — Click Convert and download your AVIF images.
Why Convert JPG to AVIF?
AVIF (AV1 Image File Format) is the next-generation image format that delivers dramatically smaller files than JPG at the same visual quality. In typical conversions, AVIF files are 50% smaller than the equivalent JPG — a 2 MB JPG photo becomes a ~1 MB AVIF with no visible difference. AVIF also supports features JPG lacks entirely: transparency (alpha channel), HDR / 10-bit color depth, and lossless compression. For web developers, converting JPG to AVIF is one of the highest-impact performance optimizations available.
JPG vs AVIF Comparison
| Feature | JPG / JPEG | AVIF |
|---|---|---|
| Compression type | Lossy only | Lossy and lossless |
| Typical file size (photo) | 1× (baseline) | ~0.5× (50% smaller) |
| Transparency | ❌ | ✅ (alpha channel) |
| HDR / 10-bit color | ❌ | ✅ |
| Animation support | ❌ | ✅ |
| Browser support (2026) | 100% | ~93% (Chrome, Firefox, Safari 16+, Edge) |
| Encoding speed | Fast | Slower (more complex codec) |
Use Cases
- Web performance — Serve AVIF to modern browsers using the
<picture>element with a JPG fallback. Page load times drop significantly with 50% smaller images. - E-commerce — Batch convert product photo libraries from JPG to AVIF to reduce bandwidth costs and improve Core Web Vitals scores.
- Photography portfolios — AVIF preserves fine detail and color gradients better than JPG at equivalent file sizes, making it ideal for showcasing photography.
- Social media assets — Smaller AVIF files upload faster and consume less mobile data for viewers.
How much smaller will my AVIF files be?
Typically 40–60% smaller than the source JPG at equivalent visual quality. The exact reduction depends on image content — photos with smooth gradients see the largest savings.
Will converting JPG to AVIF improve image quality?
No. JPG is lossy, so data was already discarded. Converting to AVIF preserves what remains but cannot recover lost detail. For best results, start from the highest-quality JPG source available.
Does AVIF work in all browsers?
AVIF is supported by Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+ — covering about 93% of users as of 2026. Use the HTML <picture> element to serve AVIF with a JPG fallback for older browsers.
Can I batch convert multiple JPG files?
Yes. Upload multiple JPG, JPEG, or JFIF files and convert them all to AVIF at once with the same Quality Preset and resolution settings.
What is the difference between Quality Preset and resolution?
Quality Preset controls the compression level (how aggressively the image data is encoded). Resolution controls the pixel dimensions. You can reduce one or both independently — lowering quality shrinks file size without changing dimensions, while reducing resolution makes the image physically smaller.
