How do I convert AVIF to PDF?

Add your AVIF file to the upload area above, then press Convert. The PDF file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to PDF reduce quality?

No. PDF is a lossless format, so the conversion preserves exactly what is in your AVIF file. Note that it cannot recover detail that was already discarded when the AVIF was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

AVIF and PDF explained

AVIF stores still images using the AV1 video codec's intra-frame compression. It generally achieves the smallest files of any widely supported format, and it handles wide colour gamut and HDR, which JPEG cannot.

PDF describes a page as a fixed arrangement of text, vector graphics and images. Unlike a word processor document, it is designed so the page looks identical everywhere — which is exactly why it is awkward to edit.

Where AVIF files come from: Performance-focused websites and modern image pipelines.
Where PDF is used: Contracts, invoices, reports, forms, academic papers and scanned documents.

AVIF vs PDF

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

AVIF compared with PDF
Property	Source	Target
Compression	Lossy or lossless	Lossy or lossless
Transparency	Yes	—
Animation	Yes	—
Introduced	2019	1993
Browser support	Modern browsers only. Limited desktop app support.	Universal.

AVIF is stronger at: The best compression of any broadly supported image format. Handles HDR and wide colour gamut. Supports transparency and animation.
PDF is stronger at: Looks identical on every device, in every viewer, when printed. Supports digital signatures, forms and embedded fonts. Universally readable without special software.

Why convert AVIF to PDF?

Converting AVIF images to PDF packages them into a single paginated document. That matters when you are submitting scans, assembling receipts, or sending several images to someone who should receive one file rather than an inbox full of attachments.

AVIF limitations that prompt the switch: Encoding is slow compared with JPEG or WebP. Desktop application support is still thin. Very low bitrates can smear fine detail in a distinctive way.
What you give up: Genuinely hard to edit — it stores positioned glyphs, not paragraphs. Scanned PDFs contain no text at all until OCR is run.

Does converting AVIF to PDF reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

A PDF full of scanned pages is a stack of pictures, not a document. Selecting text is impossible until OCR has been run over it.
