AVIF (AV1 Image File Format) is a next-generation image format that achieves significantly smaller file sizes than JPEG or WebP at the same visual quality. It is increasingly used by web platforms that need high-quality images with minimal bandwidth. Converting an AVIF to PDF makes it portable and universally viewable.
Browser support
AVIF is supported by all modern browsers but not by older systems. A PDF embedding the AVIF content is accessible on any platform — Windows, macOS, iOS, Android — through any PDF viewer, without AVIF support on the operating system.
On-device processing
The AVIF to PDF tool runs entirely in your browser. The image is decoded locally using the browser's built-in AVIF support, embedded in a PDF using pdf-lib, and downloaded to your device. No upload occurs.
When to convert AVIF to PDF
AVIF images arrive most commonly from modern web platforms: images downloaded from social media, news sites, or content delivery networks that serve AVIF for bandwidth efficiency. Converting to PDF ensures the image can be opened on any device without requiring AVIF support from the operating system or viewer.
AVIF is also the output format of some modern cameras and screen capture tools. Converting to PDF ensures the image can be shared and archived universally.
Quality and compression
AVIF achieves its small file size through a sophisticated compression algorithm based on the AV1 video codec. The quality is already baked into the AVIF file. When the browser decodes the image and embeds it into a PDF, the decoded pixels are stored. A high-quality AVIF image produces a high-quality embedded image in the PDF.
Multiple images
To combine several AVIF images into a single PDF, convert each one individually and use the Merge PDF tool to combine the resulting PDFs into one document. Each AVIF becomes one page in the final merged PDF.
