AVIF is an image format optimized for web delivery with excellent compression, while PDF is the universal standard for document sharing and printing. Converting AVIF images to PDF embeds the decoded pixel data into a PDF document structure, creating a file that can be reliably viewed, printed, and shared across any operating system and device.

This conversion is common when you need to include AVIF photographs in formal documents, create printable image portfolios, or submit images to systems that expect PDF format. The PDF wrapper adds document-level features like page sizing, margins, and metadata that pure image formats lack.

PDF is the standard format for documents that need to look identical regardless of the viewing device or operating system. When you convert an AVIF image to PDF, you create a file that can be opened by Adobe Reader, Preview, Chrome, or any PDF viewer without needing AVIF codec support. This is valuable for sharing images with people who may not have AVIF-capable software.

Many professional and institutional workflows require PDF submissions. Insurance claims, real estate listings, legal evidence submissions, academic paper figures, and government forms often mandate PDF format. Converting your AVIF images to PDF lets you incorporate modern, efficiently-compressed source images into these established document workflows.

Sharp decodes the AVIF image and produces a pixel buffer, which is then embedded into a PDF page using pdf-lib. The PDF page dimensions are set to match the image aspect ratio at 72 DPI by default, though custom page sizes (A4, Letter, etc.) can be specified. The image data within the PDF is stored as JPEG-compressed content for optimal file size. Metadata fields (title, author, creation date) can be set on the PDF.

Yes. The image is re-encoded as JPEG within the PDF, which is less efficient than AVIF compression. A 500 KB AVIF might produce a 1-2 MB PDF depending on quality settings.

This converter handles one image per PDF page. For multi-image PDFs, convert each AVIF separately and then use a PDF merge tool to combine them.

By default, the PDF page is sized to match the image dimensions at 72 DPI. You can also choose standard page sizes like A4 or Letter, in which case the image is scaled to fit within the margins.

Yes, provided the source AVIF has sufficient resolution. A 4000x3000 pixel image prints at 300 DPI on roughly a 13x10 inch area, which is suitable for A4 or Letter prints.

PDF has its own metadata format. EXIF data from the AVIF (camera model, GPS, exposure) is not automatically transferred to PDF metadata fields, which use title, author, and subject fields instead.
