Why use Aback Images for avif to pdf
Where the PDF goes next
PDF opens in every browser, operating system and office suite.
PDF next to AVIF
Both formats are lossy, so the size mostly follows the quality setting; at the default the PDF usually lands in the same range as the AVIF.
A second lossy pass
AVIF is lossy already, since it stores lossy or lossless AV1 intra-frame coding, so keep the quality at or above the default to avoid stacking a new layer of artefacts on the old one.

AVIF vs PDF
What changes from AVIF to PDF
Encoding: the AVIF uses lossy or lossless AV1 intra-frame coding; PDF uses per object: images inside are usually JPEG or Flate-compressed, and the download is a one-page PDF with the image embedded as a JPEG.
Bit depth: 8, 10 or 12 bits per channel in the AVIF; PDF allows whatever the embedded images use, and the PDF written here has 8 bits per channel. 10 and 12-bit AVIFs, including HDR ones, are decoded to 8 bits per channel.
Colour: YUV 4:4:4 or 4:2:0 with BT.709, Display P3 or BT.2020 primaries, HDR curves possible in the AVIF; PDF supports RGB, CMYK, greyscale or spot colours, written here as 8-bit sRGB.
Transparency: the AVIF stores it as an auxiliary AV1 image stored beside the colour image; the PDF has none, so transparent areas are filled with the colour you choose.
Animation: an AV1 image sequence under the 'avis' brand; the PDF holds one image, so only the first frame is converted.
Metadata: the AVIF can carry EXIF, XMP and ICC stored as HEIF items; PDF can carry document info and XMP, but nothing is copied across.
About AVIF
AVIF uses the AV1 video codec for still images. It is the most efficient widely supported format, often half the size of JPEG, with HDR, wide colour and transparency, but encoding is slow.
An AVIF is a HEIF file, the same ISO base media boxes as MP4, with the brand 'avif'. The picture is an AV1 key frame stored as an image item, and its size, colour and pixel layout are item properties.
AVIF files usually come from image CDNs, modern web build pipelines and some recent phones.
About PDF
PDF is the standard for documents that look identical everywhere. Images placed in a PDF can be printed, emailed and combined into multi-page documents.
When converting AVIF to PDF makes sense
PDF is the better choice for sharing, printing and submitting documents, while AVIF suits maximum compression on modern websites.
PDF strengths: Opens identically on every device; Multiple pages in one file; Print-ready page sizes. Drawbacks to weigh: Not an image format: harder to edit or embed.
Limitations
- Almost any other format needs more bytes than AVIF for the same picture, so expect the file to grow.
- HDR and wide-gamut AVIFs are mapped to standard sRGB on decode, so very bright highlights can look flatter than on an HDR screen.
- The page matches the image size unless you choose a paper size, and the image is embedded as a JPEG.
- To put several images into one multi-page PDF, use Image to PDF.

Frequently asked questions
Does converting AVIF to PDF lose quality?
PDF is lossy, so detail the eye barely notices is discarded to save space. The AVIF was lossy already, so keep the quality high to avoid stacking artefacts. 10 and 12-bit AVIFs, including HDR ones, are decoded to 8 bits per channel.
What happens to transparency when converting AVIF to PDF?
AVIF stores transparency as an auxiliary AV1 image stored beside the colour image. PDF has no alpha channel, so transparent pixels are composited onto a solid colour, white unless you pick another. To keep transparency, convert to PNG, WebP or AVIF instead.
Will my animated AVIF stay animated?
No. PDF holds a single image, so only the first frame is kept. Convert to animated WebP, APNG or GIF to keep the motion, or export every frame with the GIF Frame Extractor.
Can I put several images in one PDF?
This converter creates one PDF per image. To combine many images into one multi-page PDF with page size and margins, use Image to PDF.
Which apps open PDF files?
Every browser, operating system and office suite.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
