Cutting-Edge Compression

AVIF uses AV1 codec technology to achieve the smallest possible image files — your PFB font renders load faster than any other format.

Quality Preserved

Despite extreme compression, AVIF maintains excellent visual quality — font glyph edges stay sharp and detailed.

Cloud Encoding

AV1 encoding is computationally intensive — Convertio handles it on powerful servers so your device stays responsive.

About formats

PFB (Printer Font Binary) is the compact binary representation of Adobe's PostScript Type 1 font format, introduced alongside PFA in 1984. Where PFA stores the entire font program as hex-encoded ASCII text, PFB wraps the same data in a lightweight binary container that uses segment headers to mark regions as ASCII or binary. The encrypted glyph outline section (eexec) is stored as raw bytes rather than hex characters, cutting the file size roughly in half compared to PFA. Each segment begins with a marker byte and a 32-bit length field, making the format simple to parse while still significantly more compact. PFB became the dominant Type 1 distribution format on Windows and DOS platforms, used in combination with PFM (Printer Font Metrics) or AFM files that supply the character width and kerning data needed for text layout. One advantage is storage and transfer efficiency — the binary encoding means a typical text font occupies 30-50 KB rather than the 60-100 KB its PFA equivalent would require. The segmented structure also allows PostScript interpreters to stream font data efficiently, processing ASCII and binary portions with their respective handlers. Adobe Type Manager (ATM) on Windows relied on PFB files to render smooth Type 1 text on screen, a capability that transformed desktop publishing on the PC platform. While OpenType fonts have largely replaced Type 1 for new work, PFB files persist in established print workflows, archival font libraries, and systems that depend on PostScript output.

AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.

Frequently Asked Questions

Why convert PFB to AVIF?

AVIF achieves dramatically smaller file sizes than JPEG or WebP — rendering PFB font specimens in AVIF means faster page loads and lower bandwidth usage.

How to open AVIF?

AVIF is supported natively in Chrome, Firefox, Safari, Edge, and Opera. Image editors like GIMP, Photoshop (via plugin), and Squoosh also handle it.

Is AVIF better than WebP?

AVIF generally achieves better compression than WebP, especially at low bitrates. Browser support has expanded rapidly since 2023.

Does AVIF support transparency?

Yes — AVIF supports alpha transparency, HDR, wide color gamut, and both lossy and lossless compression modes.

Is this conversion free?

Yes — Convertio handles PFB to AVIF conversion at no charge, directly in your browser.
