In recent years, the demand for faster-loading websites and optimized images has made image file size a critical consideration. Among the new-generation image formats, AVIF (AV1 Image File Format) stands out for its ability to reduce file sizes dramatically without compromising visual quality. In this blog, we’ll explore how AVIF achieves its compression, provide real-world examples, and explain when it can save the most storage.
Before we dive deeper, if you’re looking for a free avif to jpg converter or an online avif to jpg converter, these tools can quickly convert AVIF images while maintaining quality, giving you the flexibility to test different formats for your projects.
How AVIF Achieves Smaller File Sizes
AVIF leverages the AV1 video codec, which is renowned for high-efficiency compression. By applying video compression techniques to images, AVIF can reduce file sizes by 30–50% compared to JPEG for the same perceived quality. Key factors behind this reduction include:
- Advanced Prediction Models: AVIF predicts pixel values using complex algorithms, storing only the difference between the predicted and actual pixel. This reduces redundant data significantly.
- Transform Coding: AVIF uses discrete cosine transforms (DCT) and other mathematical transformations to represent image data efficiently.
- Higher Bit Depth: With support for 10-bit and 12-bit color depth, AVIF compresses color more efficiently while preserving gradients and details.
- Chroma Subsampling: AVIF can reduce chroma resolution (color information) while keeping luminance (brightness) intact, which the human eye perceives as almost identical to the original.
- Transparency Support: Unlike JPEG, AVIF supports alpha channels, meaning it can handle transparency without needing extra files like PNG, often saving space.
These features collectively allow AVIF to outperform older formats like JPEG, especially for complex or high-detail images.

Real Examples of AVIF File Size Reduction
To illustrate the efficiency of AVIF, consider these real-world comparisons:
| Image Type | Original JPEG Size | AVIF Size | Size Reduction |
| Landscape | 3.2 MB | 1.5 MB | 53% |
| Portrait | 2.8 MB | 1.4 MB | 50% |
| Product Photo | 1.6 MB | 0.8 MB | 50% |
| Social Media Graphic | 1.2 MB | 0.6 MB | 50% |
These examples show that AVIF’s compression is highly effective, particularly for high-resolution images with complex color patterns. For a closer look at scenarios where AVIF truly outperforms JPEG, refer to When AVIF Outperforms JPG.

Tips to Maximize AVIF File Size Reduction
- Optimize Source Images: Starting with clean, high-quality images ensures AVIF compression performs best.
- Adjust Compression Levels: Use moderate compression for photography to maintain details, higher compression for graphics.
- Leverage Conversion Tools: Tools like avif to jpg allow you to experiment and find the right balance between quality and size.
- Batch Conversion: For multiple images, batch tools save time and maintain consistency.
FAQs About AVIF File Size Reduction
- What is AVIF, and how is it different from JPEG?
AVIF is an image format based on the AV1 codec, offering higher compression efficiency, support for transparency, and higher bit depths compared to JPEG. - How much smaller are AVIF files compared to JPEG?
Depending on the image, AVIF can reduce file sizes by 30–50% while maintaining comparable visual quality. - Does AVIF reduce image quality?
AVIF preserves quality exceptionally well. Lossless compression is possible, and even lossy AVIF usually maintains superior visual fidelity compared to JPEG. - Are all browsers compatible with AVIF?
Most modern browsers, including Chrome, Firefox, and Edge, support AVIF. Safari added support in its latest versions. - Can AVIF handle transparency like PNG?
Yes, AVIF supports alpha channels, making it ideal for images requiring transparency without extra files. - Should I always use AVIF for web images?
While AVIF is excellent for compression, consider browser support and workflow compatibility. JPEG or PNG may still be preferred for certain platforms. - How can I convert AVIF to JPEG without losing quality?
Reliable online tools or converters can safely convert AVIF to JPEG while retaining most of the image quality.
