How to Use Web Font Generator
Upload any TTF, OTF, WOFF, or WOFF2 font file to parse metadata, convert between formats (TTF, WOFF, WOFF2), preview it in your browser, and generate ready-to-use @font-face CSS code. After downloading the converted files, upload them to your server and copy the CSS snippet to use the font on your website.
Frequently Asked Questions
What font formats are supported?
TTF, OTF, WOFF, and WOFF2. Upload any of these formats and convert between them.
Can I convert OTF to TTF?
Yes. Upload an OTF file and download it as TTF, WOFF, or WOFF2.
What is WOFF2?
WOFF2 is the most modern web font format with up to 30% better compression than WOFF, supported in all major browsers.
How do I use the @font-face CSS on my website?
Copy the generated CSS, upload the downloaded font files to your server, and update the URLs in the src declarations to point to your server paths.
Is my font data safe?
Yes. All processing happens entirely in your browser. No font files are uploaded to any server.
What is the difference between TTF and OTF?
TTF (TrueType) and OTF (OpenType) are both widely used font formats. OTF supports advanced typographic features like ligatures and stylistic alternates, while TTF is simpler and more universally compatible. Both can be used on the web.
Which web font format should I use?
WOFF2 is recommended as the primary format for modern websites due to its superior compression. Include WOFF as a fallback for older browsers, and TTF as a last resort. The generated CSS includes all formats so browsers automatically pick the best supported one.
About the Web Font Generator Tool
The Web Font Generator on QuickToolSpark converts font files between formats and produces the CSS you need to embed them on your website. Upload a TTF, OTF, WOFF, or WOFF2 file, preview it with your own text, extract metadata like family name and glyph count, and generate ready-to-use @font-face CSS. Everything runs in your browser, so your font files never leave your device, which matters because fonts are valuable assets and designers often cannot upload them to random servers.
Websites cannot rely on the fonts installed on a visitor's computer. To guarantee a specific typeface appears everywhere, you embed it as a web font: a file the browser downloads and uses for the text on the page. The modern web standard is WOFF2, a compressed format that loads fast and is supported by every current browser. If your font collection has only desktop formats like TTF or OTF, converting to WOFF2 makes it ready for the web.
Why Convert to WOFF2
WOFF2 is the format browsers expect today. It compresses font data more aggressively than older formats, which means smaller files, faster page loads, and a better Core Web Vitals score. While TTF and OTF are the native formats for desktop software like Photoshop and Word, they are large and uncompressed, making them a poor fit for the web. Converting them to WOFF2 keeps the exact same glyphs and metrics while dramatically shrinking the download size.
WOFF is the predecessor format, slightly larger than WOFF2 but supported on older browsers. A well-built font stack often includes a WOFF2 file for modern browsers with a WOFF fallback for legacy ones. When you convert, you can generate both, so your site covers every visitor while still getting the compression benefits on the majority of them.
Generating @font-face CSS
The @font-face rule is how CSS declares a custom font. It names the family, points to the file location, and defines the weight and style. After uploading and converting your font, the generator produces the complete rule for you, including the font-family name, the src URL for each format, and font-weight and font-style declarations. Copy that block into your stylesheet and reference the family name in your regular CSS, and the font renders on your site.
Before publishing, check the font's license, since many desktop fonts are licensed for use on a specific number of computers and require a separate web license to serve online. After deploying, test the page on a phone and a desktop browser to confirm the font loads and that fallback fonts are set in your font-family stack in case the file is slow. Previewing with your own text before embedding also confirms the font matches the vibe you expect.
- Convert to WOFF2 for modern browsers and keep a WOFF fallback, but skip legacy-only formats unless you need deep compatibility.
- Use the preview with your own words to confirm the font's personality before committing it to a live site.
- Read the font license before self-hosting, since some fonts need a separate web license for online use.
- Add fallback font families to every font stack so your site still looks correct while the web font loads.
