When to Convert
Common scenarios where this conversion is useful
Maximum compression for web publishing
AVIF achieves the smallest file sizes of any widely-supported format. Converting PDF content to AVIF for your website reduces bandwidth usage by 50% compared to JPG and 30% compared to WebP.
High-quality document archives
AVIF supports lossless compression with better compression ratios than PNG. For archiving document images where both quality and storage efficiency matter, AVIF is the best option.
Progressive web apps and PWAs
PWAs that display document previews benefit from AVIF's tiny file sizes. Faster loading on mobile networks improves user experience and engagement metrics.
Image-heavy content platforms
If your platform displays many document thumbnails or previews, switching from JPG to AVIF cuts image bandwidth in half without visible quality loss.

Frequently Asked Questions
AVIF (AV1 Image File Format) is a next-generation image format based on the AV1 video codec. It achieves roughly 50% better compression than JPG and 20-30% better than WebP, making it the most efficient widely-supported image format available.
AVIF is supported in Chrome (85+), Firefox (93+), Safari (16.4+), and Edge. This covers the vast majority of web users. For the small percentage on older browsers, provide a JPG or WebP fallback.
AVIF uses AV1-based encoding which is computationally more intensive than JPG or WebP. The extra processing time is the tradeoff for significantly smaller file sizes. Expect 10-20 seconds for a typical PDF page.
AVIF generally produces 20-30% smaller files than WebP at equivalent visual quality. It also supports HDR and wider color gamuts. However, WebP has slightly broader browser support and faster encoding.
Most email clients don't support AVIF yet. Use JPG or PNG for email images. AVIF is best suited for web pages, apps, and platforms where you control the viewing environment.
Yes. AVIF supports full alpha channel transparency with both lossy and lossless compression, making it superior to JPG (no transparency) and GIF (binary transparency only).
The PDF is rendered at 300 DPI before AVIF compression. A letter-size page produces approximately 2550×3300 pixels.
The converter processes the first page of your PDF. Multi-page conversion is planned for a future update.
Files are uploaded via encrypted TLS, processed on our servers, and auto-deleted immediately. We never store, view, or log your documents.
Yes. ChangeThisFile supports converting AVIF to JPG, PNG, WebP, and other image formats. Use the AVIF converter page to convert back if needed.
