Frequently Asked Questions
What is an AVIF image compressor?
An AVIF image compressor reduces the file size of AVIF images while preserving visual quality. AVIF (AV1 Image File Format) is a next-gen image format that already offers superior compression compared to JPEG and PNG, and our compressor makes AVIF files even smaller for faster web loading.
Is it safe to compress AVIF images online?
Yes. All compression happens directly in your browser using client-side processing. Your images are never uploaded to a server, ensuring complete privacy and security.
How much can I reduce AVIF file sizes?
ImgSquash typically reduces AVIF file sizes by an additional 20-40% beyond the format's native compression. The exact savings depend on your image content and chosen quality settings.
Will compressing AVIF images reduce quality?
With lossless compression, there is zero quality reduction. With lossy compression, you control the quality level — most users find 80-85 quality indistinguishable from the original while achieving significant file size reduction.
