Convert Fonts to Any Format

 

Professional Font Converter Guide

Fonts are everywhere. Websites, mobile apps, printed materials, games, branding projects, documents, and user interfaces all depend on fonts working correctly across different platforms. However, not every system, browser, or application supports the same font formats. This is where a font converter becomes essential.

With our online font converter, you can convert fonts between 12+ professional font formats while preserving Unicode characters, glyph shapes, kerning, and font metrics. Whether you are a web developer, designer, printer, or typographer, converting fonts correctly ensures compatibility, performance, and visual consistency.

Why Font Conversion Is Important

Font formats were created for different purposes over decades of computing history. Desktop operating systems, web browsers, printers, and design tools all evolved separately, which resulted in many font standards.

You may need font conversion when:

  • Preparing web fonts for fast-loading websites

  • Using desktop fonts on Windows, macOS, or Linux

  • Optimizing font performance for mobile devices

  • Converting legacy fonts into modern formats

  • Ensuring full Unicode and multilingual support

  • Working with professional printing or typography workflows

A proper font converter ensures the font remains visually identical after conversion while adapting to the technical requirements of the target platform.

Desktop Font Formats Explained

TTF – TrueType Font

TTF is one of the most widely supported font formats across all operating systems. It works seamlessly on Windows, macOS, and Linux and is commonly used in desktop applications and design software.

If you are working with system fonts or design tools like Photoshop or Illustrator, TTF is often the safest choice. You can learn more about this format here:

OTF – OpenType Font

OTF extends TrueType by supporting advanced typographic features such as ligatures, alternates, swashes, and complex scripts. It is the industry standard for professional typography and multilingual projects.

OTF fonts are ideal for print production, branding, and high-quality design work.

DFONT – Mac Font Suitcase

DFONT is a legacy macOS font format used before modern versions of macOS adopted TTF and OTF. While obsolete today, DFONT files still appear in vintage Mac font collections and archives.

If you need to modernize old Mac fonts, converting DFONT to TTF or OTF is the best solution.

Font Source and Design Formats

SFD – Spline Font Database

SFD is the native editable format of FontForge and acts like the source code of a font. Designers use it to store construction details, control points, guidelines, and metadata.

SFD files are usually converted to TTF or OTF before being distributed.

UFO – Unified Font Object

UFO is a modern, open-source font source format designed for collaboration. Each glyph is stored in a separate XML file, making it perfect for version control and team-based font development.

Professional type foundries and open-source font projects rely heavily on UFO.

Web Font Formats for Websites

WOFF – Web Open Font Format

WOFF compresses TTF and OTF fonts for use on websites, reducing file size while maintaining visual quality. It is supported by nearly all browsers and remains a reliable standard.

If you are embedding custom fonts on a website, WOFF is essential.

WOFF2 – Web Open Font Format 2

WOFF2 is the modern successor to WOFF, using advanced compression for even smaller file sizes. It is supported by all modern browsers and offers the best performance.

For modern websites, WOFF2 should always be your first choice.

EOT – Embedded OpenType

EOT was created by Microsoft for older versions of Internet Explorer. While obsolete today, it may still be needed for maintaining very old websites.

SVG Fonts

SVG fonts allow multicolor glyphs and visual effects but are now deprecated for web use. They are mainly found in older projects and experimental typography.

Professional and Printing Font Formats

PFB / PFA – PostScript Fonts

PostScript fonts were the backbone of professional printing and desktop publishing. PFB is the binary version, while PFA is ASCII-based and human-readable.

They are still used in legacy print workflows and archival projects.

AFM / PFM – Font Metrics Files

These files store kerning, spacing, and font measurement data required for correct text layout in professional printing systems.

Modern websites should always use compressed web fonts instead of raw TTF or OTF files.

Convert Archives to Any Format

  ZIP, RAR, 7Z, TAR, ISO and More (With Practical Examples) Archive files are one of the most common ways people share and store data. Whether you’re downloading software, sending a folder of documents, backing up a project, or grabbing a Linux package, archives help you bundle many files into one and often reduce size through compression. Still, archive compatibility problems are everywhere: “This RAR won’t open on my Mac.” “My ZIP is huge, can I make it smaller?” “I downloaded a TAR.GZ from GitHub, Windows doesn’t know what to do with it.” “I have an ISO but I don’t want to burn it or mount it, I just need the files.” This guide explains archive formats clearly and shows how to choose the best format based on compatibility, size, and workflow.
