AVIF to PDF: what changes and when it makes sense

AVIF is an AV1 Image File Format. It is best known for the smallest files of any common web format at a given quality. The main drawbacks are slow encoding, patchy support outside browsers, and smoothing in fine textures at aggressive settings.

PDF is a Portable Document Format. It is best known for a fixed layout that prints and displays identically everywhere. The main drawbacks are not being an image format, so pages cannot be dropped into an img tag without rendering them first.

AVIF vs PDF at a glance

Property	AVIF	PDF
Type	Raster image	Container format
Compression	Lossy or lossless, based on the AV1 video codec	A container for text, vector shapes and images. Embedded photos are usually JPEG or lossless Flate
Transparency	Full alpha channel with soft edges	Pages render on an opaque background
Animation	Yes	No
Colour depth	8, 10 or 12 bits per channel, with HDR and wide-gamut support	Depends on the embedded images
Support	Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it	Opens on every device, with a built-in viewer in all major browsers
History	Finalised in 2019 by the Alliance for Open Media (Google, Mozilla, Apple, Microsoft, Netflix, Amazon, Intel and others). Based on AV1 video codec, successor to VP9 and HEVC. First major browser support: Chrome 85 (2020).	Developed by Adobe in 1993 as a way to share documents with fixed layout. Became an open ISO standard (ISO 32000) in 2008. PDF 2.0 (ISO 32000-2) was released in 2017. The most common document format for business globally.

What actually changes in this conversion

The AVIF image is placed on a PDF page. The PDF is mainly a wrapper around the image.
PDF cannot store transparency, so transparent areas are filled with white.
AVIF can hold animation, but PDF cannot, so the result is a single still frame.
Browser-based conversion works in 8-bit sRGB. Wide-gamut, 10-bit and 16-bit data are reduced. For colour-critical work, keep the original.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About AVIF: history and technical details

Finalised in 2019 by the Alliance for Open Media (Google, Mozilla, Apple, Microsoft, Netflix, Amazon, Intel and others). Based on AV1 video codec, successor to VP9 and HEVC. First major browser support: Chrome 85 (2020).

Technical: AV1 intra-frame coding with variable block sizes from 4x4 to 128x128. Supports 8/10/12-bit colour, HDR, wide gamut (BT.2020), monochrome. HEIF-based container. Encoding is 10-100x slower than JPEG.

Real-world size: AVIF at quality 50 produces files 30-50% smaller than JPG at quality 85 with similar visual quality. Netflix reports 50% bandwidth savings after switching. Google reports AVIF is 20-30% smaller than WebP.

Popular tools: Adobe Photoshop 2024+, GIMP 2.10+, Squoosh, avifenc, ImageMagick, AVIF.io, Netflix (production use).

Alternatives: WebP (faster encode, less compression), JPG (universal), HEIC (Apple-only), JPEG XL (future format).

About PDF: what you get

Developed by Adobe in 1993 as a way to share documents with fixed layout. Became an open ISO standard (ISO 32000) in 2008. PDF 2.0 (ISO 32000-2) was released in 2017. The most common document format for business globally.

Technical: Object-based file structure with cross-reference tables. Supports text, vector graphics, images, fonts, forms, JavaScript and digital signatures. Pages are rendered to a fixed canvas. Can embed JPEG, PNG, JPEG 2000 and JBIG2 images.

Real-world size: A scanned A4 document at 300 DPI is 1-5 MB. The same pages as JPG are 200 KB to 1 MB each. A text PDF of 100 pages is 200-500 KB. A photo-heavy PDF can be 50-100 MB.

Popular tools: Adobe Acrobat, Preview (macOS), Foxit Reader, SumatraPDF, Chrome (built-in viewer), Ghostscript, qpdf.

Alternatives: Word document (editable), HTML (web-native), JPG/PNG (single page), ePub (eBooks).

Browser and software compatibility

AVIF: Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it. PDF: Opens on every device, with a built-in viewer in all major browsers.

PDF output opens on every device, and almost every portal that accepts documents accepts PDF.

Why people move away from AVIF

Outside browsers, AVIF support is thin. Many editors, email clients and social platforms cannot open it.
Uploaders that accept only JPG or PNG reject AVIF files.
Fine texture such as film grain or fabric can look smoothed at aggressive AVIF settings.

Why people choose PDF

PDF is the expected format for applications, forms, invoices and anything that will be printed.
An image placed in a PDF looks the same on every device and prints at the right size.
Many portals accept PDF only for ID and proof documents.

Common mistakes with AVIF

Encoding AVIF at quality 90 thinking it will match JPG 90 — AVIF scale is different
Using AVIF for small icons — encoding overhead wastes savings
Expecting Photoshop (pre-2024) to open AVIF files — it will not

Best practices for keeping quality

AVIF files are often made for the web already. If you need to edit one, convert from the original source rather than stacking another lossy pass.
Order and orientation matter, so check them before saving, especially for photos taken sideways on a phone.
A photo of a document stays a photo inside the PDF. The text will not be searchable unless you run OCR.
Resize before converting if the image will be shown small. A 4000 pixel photo displayed at 800 pixels wastes bytes in any format.
Check the result at 100 percent zoom, especially around text, edges and gradients, before you replace any originals.
Keep your original files. Conversions to a lossy format cannot be undone.
When you convert a set of images, use the same quality setting for the whole batch. The converter handles up to 20 files at once.

AVIF to PDF questions

Quick answers about privacy, quality, supported formats, file limits and how PDF works.

Why convert AVIF to PDF?

PDF files are typically smaller than AVIF, which makes them faster to share, send and load. The trade-off is a small amount of image detail at low quality settings.

Will converting AVIF to PDF lose quality?

At 90% quality, most people cannot tell the difference. Use 85-95% for photos and you are fine.

Does PDF keep transparency?

No. PDF does not support transparency. Transparent areas will be filled with white.

Are my files uploaded?

Never. Everything runs in your browser. Your files never leave your device. Open DevTools Network tab while processing — you will see no upload request.

Can I convert many files at once?

Yes, up to 20 files at once. Download them individually or all together as a ZIP.

Does the converter strip metadata?

Yes. Browsers do not pass EXIF data through a canvas, so GPS, camera model and dates are removed on every conversion. That is good for privacy.

Is it free?

Yes. No credits, no daily cap, no account, no watermark. The practical limit is your device memory.

Can browsers display PDF?

Yes. Chrome, Edge, Firefox and Safari all have built-in PDF viewers. On mobile, PDF opens in the OS viewer. You can also use the browser to render a page as an image.

Why does my PDF-to-image look blurry?

Browser PDF rendering produces a fixed resolution. If you convert at 800px width and view at 1600px, it will blur. Convert at a higher resolution (1200-2400 px) for print or high-DPI use.

Your files never leave your device

No upload, no account, no tracking. Everything happens in your browser using the Canvas API and WebAssembly. You can confirm this in your browser's DevTools Network tab while the tool runs — no request carries your file. See why ToolDeck is different.
