AVIF Compression Tips
Start at Quality 75-80
AVIF handles low quality settings better than JPEG. At quality 75, most AVIF images look virtually identical to quality 100, making aggressive compression practical.
Compare Before and After
AVIF compression artifacts differ from JPEG — they tend to smooth details rather than create blocky artifacts. Preview your compressed images to find the right balance.
Consider Your Source
If your AVIF files were originally converted from high-quality JPEGs or PNGs, there is usually room for further compression without visible quality loss.
100% Private Compression
Unlike online compressors that upload your images to their servers, PhotoFormatLab processes everything locally in your browser. Your files are never transmitted anywhere — they stay on your device.
Safe for personal photos, business documents, and confidential images.
Frequently Asked Questions
AVIF files are compressed, but the initial quality setting may be higher than needed. Reducing quality from 90 to 75 can cut file sizes significantly with no visible difference on screen.
For web images, quality 70-80 gives excellent results. AVIF handles low quality much better than JPEG — it produces fewer visible artifacts at aggressive compression levels.
AVIF uses lossy compression by default, so reducing quality does remove some image data. However, AVIF is designed so that quality loss is minimally perceptible even at lower settings.
