What's the difference between AVIF and PDF?

AVIF is the newest mainstream image format, built on top of the AV1 video codec. PDF is the universal document format.

What quality should I pick?

For PDF, quality 75-85 is the sweet spot — small files with no visible difference from the original. Lower than 60 starts to show artifacts. Higher than 90 mostly just makes the file bigger.

Why convert away from AVIF?

AVIF is the newest mainstream image format, built on top of the AV1 video codec. Where it falls down: on-the-fly conversion where the user is waiting (slow encode); older devices and software pipelines; anything that needs to round-trip through editing tools (limited support). PDF addresses that for most workflows.

When is PDF the right format?

PDF is a good choice for: documents that need to print or render identically across devices; multi-page reports and contracts; combining multiple images into a single shareable document. It is a poor choice when anywhere you need to edit the content after the fact (PDFs are read-mostly).

Anything surprising about AVIF or PDF?

AVIF encoding is single-threaded by default — large images can take 5–10 seconds in browser. And on the PDF side: browsers can render PDFs in-page — no plugin required since around 2015.

Does this work on mobile?

Yes. The drop zone falls back to your phone's file picker, and conversions run on-device just like desktop. Large files may be slower on mobile due to CPU and memory constraints, but the workflow is identical.

What's the maximum file size?

No hard limit — the browser handles it. Files under 50MB convert in a few seconds. Larger files work but may take longer as the browser allocates memory. If you hit issues, batch in smaller groups.

Can I combine multiple images into one PDF?

Yes. Drop multiple AVIF images and they'll be combined into a single PDF, one per page. Drag the queue to reorder pages before exporting.

Overview

Why convert AVIF to PDF

AVIF has limited compatibility — supported in chrome, firefox, safari 16+, and edge. pre-2022 devices may not decode it. PDF is broadly supported, which is the most common reason to convert. AVIF is already efficiently compressed, so the size difference may be modest.
