AVIF to PDF Converter

What Is AVIF to PDF Conversion?

AVIF to PDF conversion transforms a modern AVIF image into a universal PDF document. AVIF (AV1 Image File Format) was introduced by the AOMedia alliance in 2019 as a modern image storage format with highly efficient compression. PDF (Portable Document Format) is the document exchange standard that displays identically on any device and operating system.

Unlike conversion between raster formats, transforming AVIF to PDF changes the very nature of the file: from an image, it becomes a document container. This opens new possibilities - adding metadata, password protection, digital signatures, annotations, combining with other pages. A PDF document can be opened on any device without specialized image viewing software and without worrying about whether the viewer supports modern formats.

AVIF to PDF conversion is particularly useful when you need to share an image with a recipient who may not have an up-to-date operating system or viewer with AVIF support. Although AVIF is supported by modern browsers, many desktop applications (especially corporate, government, and specialized software) still cannot open this format. PDF eliminates this problem: it opens on any system, from Windows XP to a modern smartphone.

About the AVIF Format

AVIF stands for AV1 Image File Format - an image format that uses the compression technology from the AV1 video codec. The AV1 codec was developed by the AOMedia alliance (Alliance for Open Media), which includes Google, Mozilla, Microsoft, Netflix, Amazon, Apple, Intel, Cisco, and other major technology companies. The AVIF standard was published in 2019 and is fully open and royalty-free - it does not require licensing fees for use.

AVIF was created as a response to the problems of older formats: JPG does not support transparency and copes poorly with modern compression demands, PNG is too heavy for photographs, WebP does not cover HDR and wide color spaces. AVIF solves all these problems in a single format, providing significantly better quality at a smaller file size.

Compression Efficiency

AVIF demonstrates outstanding compression metrics:

• 50% more efficient than JPG - at the same visual quality, an AVIF file takes on average half the space
• 20-30% better than WebP - surpasses even Google's more recent format
• Comparable to JPEG XL - competes with other modern solutions at similar quality

This means that a photo weighing 1 MB in JPG, in AVIF at the same quality may take only 400-500 KB. For web development, this is enormous savings: pages load faster, users save bandwidth, search engines rank fast sites better.

Technical Capabilities

AVIF supports a wide range of modern features:

• 8/10/12 bits per channel - instead of 8 bits in JPG, which allows storing more color gradations
• HDR (High Dynamic Range) - extended dynamic range for modern displays
• Wide color spaces - BT.2020, P3, sRGB, ProPhoto
• Transparency - alpha channel with any degree of semi-transparency
• Animation - frame sequences in a single file, like GIF but more efficient
• Lossless and lossy compression - can be saved both without loss and with configurable quality
• 4:4:4, 4:2:2, 4:2:0 chroma subsampling - flexible configuration for different tasks

Files have the .avif extension and image/avif MIME type. Internally, AVIF uses an ISOBMFF-based container (the same as MP4), simplifying integration with media infrastructure.

Differences from Other Formats

Let's compare AVIF with other modern competitors:

The main competitive advantage of AVIF over HEIC is its openness and absence of licensing fees. The main advantage over WebP is significantly better compression and HDR support.

AVIF Compatibility

Despite its technical merits, AVIF has not yet become a universal format - not all programs can open it. This is one of the main reasons why users convert AVIF to PDF.

Browser Support

• Chrome 85+ (August 2020) - full support
• Firefox 93+ (October 2021) - full support
• Safari 16+ (September 2022) - on iOS and macOS
• Edge 121+ (January 2024) - after a long wait

Modern browsers open AVIF without issues, but this is not always convenient: to view an image, you need to drag it into the browser window or open it via "Open with".

Desktop Application Support

• Windows 10/11 - built-in support appeared with updates, but requires installing AV1 Video Extension from the Microsoft Store
• macOS Ventura+ - built-in support through Preview
• Linux - depends on the distribution; usually supported by modern graphics editors and image viewers

Corporate office applications (Microsoft Office, Outlook) still don't work with AVIF directly - the image must first be converted. The same applies to many government and banking systems.

Graphics Editor Support

• Adobe Photoshop 23.2+ - support via plugin
• GIMP 2.10+ - support through an additional module
• Affinity Photo - support from version 2.0
• Krita - supports from version 5.0

Comparing AVIF and PDF

Technical Specifications

When to Choose AVIF

AVIF is the optimal choice for web development and photo storage:

• Websites - significant bandwidth savings and faster page loads
• Photo archive storage - smaller size at the same quality
• Modern applications - use of HDR and wide color spaces
• Animated images - efficient replacement for GIF
• Graphics with transparency - alternative to PNG with smaller size

When to Choose PDF

Converting to PDF is necessary when:

• Compatibility above all - PDF opens on any system, even outdated ones
• Business correspondence - PDF is the standard for document exchange
• Printing - printers correctly handle PDF on any device
• Archiving - PDF/A was specifically created for long-term storage
• Government submissions - many services only accept PDF
• Edit protection - PDF is harder to modify than AVIF
• Recipient cannot open AVIF - old systems, corporate software

Technical Aspects of AVIF to PDF Conversion

How the Conversion Works

When converting AVIF to PDF, the image goes through several stages:

Image quality is fully preserved during conversion. However, it's worth considering: PDF in mass-market standards stores raster embeds in 8-bit representation, so if your AVIF uses 10 or 12 bits per channel, conversion to 8 bits occurs during embedding. For most tasks (screen viewing, printing on a regular printer) this loss is imperceptible, but for professional HDR graphics it should be taken into account.

PDF Page Sizes

When converting, the following standard page sizes are available:

The "Auto" mode creates a page exactly matching the image size without white borders. This is convenient when preserving original proportions matters - for example, for wide-format photos or images with unusual aspect ratios.

Orientation and Margins

You can explicitly choose page orientation - portrait or landscape. Landscape works well for landscape photos, portrait for vertical shots and standard documents. Margin options are available: none, small, normal, large.

Use Cases for AVIF to PDF Conversion

Image Sharing

Suppose you downloaded a beautiful image in AVIF format from a modern site or received it from an acquaintance with a recent smartphone. You want to share this image with a colleague or relative who has an older version of Windows or an outdated Mac. PDF becomes a universal "envelope" - the recipient is guaranteed to open the document and view the image.

Document Submission to Government Portals

Many government and municipal portals still only work with traditional formats: JPG, PNG, PDF. If your smartphone saves photos as AVIF (newer Android models do this), it needs to be converted before uploading. PDF is the universal option that any portal will accept.

Archiving Web Materials

Web developers, designers, and SEO specialists often save materials from websites for portfolios or analysis. AVIF is becoming a web graphics standard, and saving such materials in the original format is not always convenient for subsequent viewing. PDF turns them into standalone documents that can be archived, transferred to another computer, or sent to a client.

Printing Images

When preparing AVIF for printing, a problem arises: print shops and photo labs rarely accept this format. Converting to PDF solves the issue - printers and printing equipment work with PDF as a standard. Additionally, PDF allows configuring the page size for the paper used.

Submitting Applications and Resumes

If you need to attach an image to a resume or application (a photo, portfolio, document), AVIF is not the best choice - not every recruiter or HR employee knows what it is and how to open it. PDF immediately removes any questions: the format is familiar to everyone.

Conversion Quality

Preserving Image Quality

When converting AVIF to PDF, image quality is preserved. All pixels of the source are transferred to the final document. Colors are adapted to the standard PDF color space, which for most tasks does not lead to visible changes. If your AVIF does not use HDR and is stored in 8-bit representation, the conversion happens losslessly.

Resulting File Size

It's important to understand a key feature here: AVIF itself is highly efficient in compression. When embedding images, PDF does not use AV1, so the PDF size will almost always be larger than the source AVIF size, often 2-3 times larger. This is not a disadvantage of conversion but a property of the formats: you get the universality of PDF at the cost of an increase in file size.

PDF Compatibility

Viewing Software

PDF opens on virtually any device:

This universal compatibility is precisely the key reason for converting AVIF to PDF: you eliminate the risk that something won't open for the recipient.

PDF Editing

After conversion, you can further process the PDF:

• Add text - captions, comments, annotations
• Apply stamps - date, "Certified Copy", logo
• Add signature - handwritten or digital
• Password protect - restrict opening or editing
• Add watermark - copyright protection

Adobe Acrobat, Foxit PDF Editor, PDF-XChange Editor, and many online services are suitable for editing.

Working with Different Types of AVIF

Smartphone Photos

Modern smartphones (especially on Android) can save snapshots directly as AVIF to save space. These files usually contain EXIF metadata with shooting orientation. The converter automatically applies the correct rotation so that the image in the PDF displays the same as on the camera screen.

Web Graphics

AVIFs downloaded from sites are often optimized for the web - they have moderate resolution and aggressive compression. When converting to PDF, they retain their size and quality, which is usually sufficient for re-viewing.

HDR Images

Professional HDR shots in AVIF use 10 or 12 bits and extended dynamic range. When converting to standard PDF, a transition to 8 bits occurs, which may slightly change the overall tone of the image, especially in very bright and very dark areas. For critical tasks, specialized graphics editors are recommended.

History of the AVIF Format

AVIF emerged as a byproduct of video codec development. In 2015, the AOMedia alliance began developing the open AV1 video codec, which was intended to be a response to proprietary HEVC and provide better video compression without licensing fees. AV1 was released in 2018 and quickly became an important player in streaming.

The logical next step was applying AV1 technologies to static images. In 2019, the AVIF specification was published as an open standard. By 2020, browser support appeared: first Chrome, then Firefox, Safari, and Edge. By 2024, AVIF is supported by all major browsers.

Today, AVIF is actively gaining popularity: Netflix uses it for posters, Wikipedia is gradually transitioning to this format, many CMS systems add automatic generation of AVIF versions of uploaded images. However, in the corporate world, older formats (JPG, PNG) and PDF still dominate - and this is precisely why AVIF to PDF conversion remains a relevant task.
