PDF to AVIF: what changes and when it makes sense

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 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 vs AVIF at a glance

Property	PDF	AVIF
Type	Container format	Raster image
Compression	A container for text, vector shapes and images. Embedded photos are usually JPEG or lossless Flate	Lossy or lossless, based on the AV1 video codec
Transparency	Pages render on an opaque background	Full alpha channel with soft edges
Animation	No	Yes
Colour depth	Depends on the embedded images	8, 10 or 12 bits per channel, with HDR and wide-gamut support
Support	Opens on every device, with a built-in viewer in all major browsers	Supported by current Chrome, Edge, Firefox and Safari, but many editors, social platforms and OS viewers cannot open it
History	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.	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).

What actually changes in this conversion

A PDF page is rendered to pixels when you convert it. Text and vector artwork become pixels at that resolution.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About PDF: history and technical details

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).

About AVIF: what you get

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).

Browser and software compatibility

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

AVIF is well supported by current browsers but is still rejected by many editors and social platforms.

Why people move away from PDF

A PDF page cannot be used in an img tag, a slide or a social post, so you need an image.
Turning a page into PNG or JPG is the quickest way to share one page or reuse it in a design.
Some forms and CMS uploaders accept images but reject PDF.

Why people choose AVIF

AVIF often produces files 30 to 50 percent smaller than JPG at comparable quality.
It can carry 10-bit and HDR content that JPG and WebP cannot.
It pays off most on hero images and large photo galleries, where bytes matter the most.

Common mistakes with PDF

Assuming PDF text is searchable — scanned PDFs are images, need OCR
Not checking page orientation — sideways photos stay sideways
Embedding large images at full resolution — balloons file size

Best practices for keeping quality

Converting a PDF page produces pixels at a fixed resolution. Choose a size large enough for the final use, because text will not sharpen later.
AVIF quality numbers do not line up with JPG. Start around 60-70 and compare against the original at 100 percent zoom.
Serve AVIF with a WebP or JPG fallback using the picture element so older browsers still get an image.
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.

PDF to AVIF questions

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

Why convert PDF to AVIF?

AVIF files are typically smaller than PDF, 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 PDF to AVIF lose quality?

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

Does AVIF keep transparency?

Yes. AVIF supports full transparency, so transparent areas in your original are kept.

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.

Is AVIF smaller than WebP?

Yes, typically 20-30% smaller at similar quality. But AVIF is much slower to encode and has less software support outside browsers.

Does AVIF support HDR?

Yes. AVIF supports 10-bit and 12-bit colour, HDR (Hybrid Log-Gamma and PQ), and wide-gamut BT.2020 colour. JPG and WebP cannot do this.

Can AVIF be animated?

Yes, though animated AVIF support is still limited in browsers. Chrome and Firefox support it, Safari does not as of early 2026.

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.
