AVIF to PDF converter: free, fast and secure
Need to change an image from AVIF to PDF? This tool does it instantly and for free, without uploading your pictures anywhere. AVIF is new, so desktop apps, older phones and many upload forms cannot open it yet. PDF is far more compatible. A PDF is easy to email, print and upload to college, bank and government portals, and you can combine several images into one document.
Unlike most converters, ConvertKaro never uploads your images. The conversion happens on your own device, so it is quicker, there are no file limits, and your photos stay private.

What is AVIF?
AVIF is the newest mainstream image format, based on the AV1 video codec. It often makes files 30–50% smaller than JPG and noticeably smaller than WEBP at the same visual quality, with support for transparency, HDR and wide colour. Modern browsers display AVIF, but many desktop apps, older phones and upload forms still cannot open it.
What is PDF?
PDF is the universal document format. A PDF looks the same on every phone, computer and printer, which is why banks, colleges, government offices and employers ask for documents as PDF. Putting images in a PDF also lets you combine many photos, such as scanned pages or ID cards, into a single file that is easy to email or upload.
When should you convert AVIF to PDF?
- Submitting scanned documents and certificates
- Combining photos of pages into one file
- Emailing receipts, bills and ID cards
- Printing images on standard A4 paper
Tips for the best PDF results
- Scanned pages look best on A4 with a small margin. Use Images to PDF if you want to reorder pages first.
- If your image has a transparent background, pick a background colour that matches where the image will be used.
- You can convert many AVIF files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original AVIF files until you have checked the converted PDF images.
How AVIF to PDF keeps your photos and images private
When you add a file to AVIF to PDF, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential photos and images like ID proofs, bank documents, contracts and family photos.

Frequently asked questions
Will converting AVIF to PDF reduce quality?
PDF uses lossy compression, so a tiny amount of detail is removed. With the quality slider at 90% (our default) the difference is practically invisible, and you can raise it to 100% if you need maximum quality.
Does PDF keep transparency from AVIF?
PDF does not support transparency, so transparent areas are filled with a background colour. White is the default, and you can pick any colour before converting.
Can I convert multiple AVIF files to PDF at once?
Yes. Select or drop as many AVIF images as you like. Each one is converted separately, and you can download them all together as a ZIP file, or combine them into one PDF.
How do I combine several AVIF images into one PDF?
Add all the images, keep “Combine all images into one PDF” ticked, and press Download PDF. Each image becomes one page, in the order you added them.
Is AVIF to PDF really free?
Yes, completely free. You can use it as many times as you want, and every option on the page is included at no cost.

Yes. Your files are processed inside your own browser and are never uploaded to our servers, so nobody else can see them.

Yes, the tool is built mobile-first. Open this page on your phone, add your files and download the result directly.
