How Do You Convert AVIF to PDF?
You convert AVIF to PDF by adding the images to QuickCatPDF's AVIF to PDF tool and clicking Convert to PDF. The tool turns AVIF, a newer image format that many apps can't open yet, into a PDF that works on any device, and unlike a typical AVIF to PDF online service, it works in your browser without uploading the files.
AVIF images often come from websites and newer phones. Once they're in a PDF, you can email, print or attach them to forms without compatibility problems.
How to Convert AVIF to PDF With QuickCatPDF
Converting AVIF images takes four steps.
- Click Select images or drop your .avif files on the page.
- Put the thumbnails in the order you want; rotate or remove any image.
- Check Image quality (High by default) and choose Page size and Margins if you'll print.
- Click Convert to PDF, then Download PDF.
Set Output to PDF per image (ZIP) if you want a separate PDF for each image.
Why Use QuickCatPDF for AVIF to PDF?
QuickCatPDF makes AVIF images readable everywhere. Many photo viewers, office programs and upload forms still reject AVIF, but almost every device opens a PDF.
Your images never leave your device, because your browser does the conversion. The page also keeps working offline after your first visit.
The default Image quality is High. AVIF images are already tightly compressed, so a lossless copy can make the PDF many times larger than the AVIF file without looking any better. Choose Original (no quality loss) if you need exact pixels. Transparency is kept, and you can switch Background for transparent areas to White for printing.
What Is an AVIF File?
AVIF (AV1 Image File Format) is an image format based on the AV1 video codec from the Alliance for Open Media, released in 2019. It usually makes smaller files than JPG or WebP at similar quality and supports transparency, HDR and wide colour.
All current versions of Chrome, Edge, Firefox and Safari can display AVIF, which is why it's spreading across the web. Support in desktop software is still patchy, so converting to PDF is often the easiest way to share AVIF images.
What Gets Lost When Converting AVIF?
The picture itself is kept, but a few advanced features aren't. HDR brightness and 10- or 12-bit colour are converted to standard 8-bit colour, which looks the same on most screens and printers.
Animated AVIF files become one page showing the first frame, because PDFs can't play animation. For animations you want frame by frame, convert them to GIF and use GIF to PDF.
Can You Mix AVIF With Other Image Formats?
Yes, you can add JPG, PNG, WebP and other images alongside AVIF, and they'll all go into one PDF in the order you choose. For bigger mixed batches, the Image to PDF page accepts every format the site supports, and WebP to PDF covers the other popular web format.
iPhone photos in HEIC convert on HEIC to PDF, and everyday photos on JPG to PDF.
Frequently asked questions
Why can't my browser open AVIF files?
Very old browsers don't support AVIF. If the tool says your browser can't open AVIF images, update it or use a current version of Chrome, Edge, Firefox or Safari, all of which decode AVIF.
Is there a free AVIF to PDF converter?
Yes, it's free with no sign-up, no watermark and no daily limit.
Are my AVIF images uploaded?
No, the conversion runs on your device and nothing is sent to a server. You can check by switching off your internet after the page loads: the tool still works.
Does the PDF keep the AVIF quality?
At the default High setting, the difference isn't visible in normal viewing. For a pixel-exact copy, choose Original (no quality loss), which makes a larger PDF.
Can I convert AVIF to PDF on a phone?
Yes, on any recent Android or iPhone browser. Tap Select images, choose your files, convert and download.
What is the largest AVIF I can convert?
Each file can be up to 100 MB and 100 megapixels. Batches above 150 images or 500 MB show a warning, because they depend on your device's memory.
