How Do You Convert PDF to AVIF?
You convert PDF to AVIF by opening the PDF in QuickCatPDF's PDF to AVIF tool, choosing pages and quality, and clicking Convert to AVIF. Each page becomes an AVIF image, usually the smallest file size of any common format, which is ideal for fast-loading websites.
The tool has its own AVIF encoder built in, so it works in your browser without uploading the PDF or installing software.
How to Convert PDF to AVIF With QuickCatPDF
Converting PDF pages to AVIF takes four steps.
- Click Select PDF file or drop the PDF on the page.
- Tick the pages you want or type a range in Pages.
- Choose AVIF quality (High, Medium, Low or Lossless), the Resolution and the Background.
- Click Convert to AVIF, then download the image or the ZIP.
The first time you convert, the browser downloads the AVIF encoder (about 3.5 MB). After that it's stored, so later conversions start straight away and also work offline.
Why Use QuickCatPDF for PDF to AVIF?
QuickCatPDF makes AVIF output available in any browser. Browsers can display AVIF, but most can't save it from a web page by themselves, so the encoder is included in the tool.
AVIF files are typically smaller than WebP or JPG at the same visual quality, which means faster pages and less bandwidth. A Lossless option keeps every pixel, and transparent backgrounds are supported.
The trade-off is speed: AVIF takes longer to create than JPG. In our test, two A4 pages took about 4 seconds on a cloud machine; phones may take longer for many pages.
What Is AVIF?
AVIF (AV1 Image File Format) is an image format based on the AV1 video codec from the Alliance for Open Media. It supports high compression, transparency and wide colour, and all current versions of Chrome, Edge, Firefox and Safari can display it.
Because it's newer, some older software can't open AVIF yet. For maximum compatibility use PDF to JPG; for web images with wider support, PDF to WebP is a good middle ground.
Which AVIF Quality Should You Choose?
High keeps text and edges clean and is the best default for document pages. Medium and Low make smaller files for previews and thumbnails, and Lossless keeps every pixel exactly, at a larger size.
Pair the quality with a sensible resolution: 150 DPI for most web pages, 72 DPI for small previews.
Frequently asked questions
Is there a free PDF to AVIF converter?
Yes, QuickCatPDF is free, with no sign-up, no watermark and no daily limit.
Why is AVIF conversion slower than JPG?
AVIF compresses much harder than JPG, which takes more computing work. Converting fewer pages at a time, or at a lower resolution, speeds it up.
Are my PDFs uploaded?
No, the AVIF encoder runs in your browser, so the PDF and the images stay on your device.
Can I view AVIF files on my computer?
Yes, in any current web browser. Many image viewers support AVIF too; if yours doesn't, convert the pages to JPG or PNG instead.
Can I turn AVIF images back into a PDF?
Yes, AVIF to PDF combines AVIF images into one PDF. For other formats, see PDF to Image.
