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.

WebP is an image format developed by Google, announced on September 30, 2010, designed to provide superior compression for web images in both lossy and lossless modes. The lossy mode is derived from the VP8 video codec's intra-frame coding (the same technology used in WebM video), applying block prediction, transform coding, and adaptive quantization to photographic content. The lossless mode uses a distinct algorithm combining predictive coding, color space transforms, backward reference to repeated pixel patterns, and entropy coding. WebP also supports alpha transparency in both modes — lossy WebP with transparency is unique among common web formats, offering semi-transparent images at much smaller sizes than PNG. The format supports animated sequences as well, providing a modern alternative to GIF with full-color support and dramatically better compression. One advantage is substantial file size reduction — lossy WebP produces images 25-35% smaller than JPEG at equivalent visual quality, and lossless WebP is typically 26% smaller than PNG, directly improving web page loading speed and reducing bandwidth costs. Universal browser support provides another key strength: Chrome, Firefox, Safari, Edge, and all mobile browsers now render WebP natively, achieving the broad adoption threshold needed for practical deployment. Google's core web infrastructure (Search, YouTube thumbnails, Gmail) uses WebP extensively, and the format is supported by major CDN platforms, CMS systems, and image processing services. WebP has established itself as the primary modern alternative to JPEG and PNG for web content.

Frequently Asked Questions

Why convert PFB to WebP?

WebP delivers smaller files than JPEG or PNG at comparable quality — making it the best format for font specimen images on today's web pages and apps.

How to open WebP?

WebP is natively supported in Chrome, Firefox, Safari, Edge, and Opera. It also opens in Photoshop, GIMP, IrfanView, and modern image viewers.

Does WebP support transparency?

Yes — WebP supports alpha transparency like PNG, so your rendered font glyphs can sit on transparent backgrounds for flexible web design use.

Is WebP better than PNG for font images?

For web delivery, yes — WebP produces smaller files while maintaining visual quality. For archival or offline use, PNG may be preferred for its broader compatibility.

Is there a cost for conversion?

No — Convertio provides free PFB to WebP conversion in your browser, with no signup or software download needed.
