AVIF Compressor
Compress images to AVIF format and reduce file size while maintaining quality.
100% Client-Side Processing
Most formats compress in your browser. HEIC/HEIF requires server-side conversion; those files are uploaded temporarily for processing and then deleted.
Supported formats: JPG/JPEG, PNG, WebP, GIF (static only), AVIF, HEIC/HEIF, SVG (rasterized). Recommended: up to 20MB per image. Maximum: ~50MB. Maximum image size: 8192×8192 pixels (most formats); HEIC/HEIF: 4096×4096 pixels

What is AVIF compression?
Image compression reduces file size while keeping an acceptable level of visual quality.
This tool outputs AVIF. Use the quality guide below to choose the right trade-off for web, email, or storage.
How it Works
- Upload an image.
- Choose output format (AVIF).
- Adjust quality and optionally resize.
- Download the compressed image.
Compression Settings
Quality (JPG/WebP/AVIF)
Higher quality preserves more detail but increases file size. For most web photos, 70–85% is the sweet spot.
Maximum width
Resizing reduces pixel count and is often the biggest lever for file size reduction.
Which Format Should I Use?
JPG/JPEG
Best for photos and images with lots of colors
- Universal compatibility (works everywhere)
- Great compression for photos
- No transparency support
- Lossy: loses quality with each save
PNG
Best for graphics, logos, and images needing transparency
- Supports transparency
- Lossless (no quality loss)
- Larger file sizes than JPG
- Not ideal for photos
WebP
Best for modern websites (great balance)
- 25-35% smaller than JPG at same quality
- Supports transparency
- Good for both photos and graphics
- Not supported in very old browsers (IE11)
AVIF
Best for cutting-edge web performance
- 30-50% smaller than JPG at same quality
- Supports transparency
- Next-generation format
- Limited browser support (2020+)

Common Use Cases
- Website optimization: reduce image file sizes to improve page load times.
- Email attachments: shrink images to avoid size limits.
- Storage savings: reduce disk usage for image libraries.
Frequently Asked Questions
Yes for lossy formats. With quality settings of 70–85%, the difference is often minimal while still reducing file size significantly.
For most formats, processing happens entirely in your browser and your image is never uploaded. HEIC/HEIF requires server-side conversion and is uploaded temporarily for processing and then deleted.
