When to Use Font Hinting Remover
Web Font Size Optimization
Remove font hinting before converting TTF to WOFF or WOFF2 for web delivery — hinting tables add 2–15% to font file size with zero benefit on modern high-DPI screens. Smaller web fonts improve page load times and Core Web Vitals LCP scores.
Next.js and React Font Bundles
Remove hinting from fonts used in Next.js, React, and Vue projects before adding them to your public folder. Dehinted fonts load faster and are fully compatible with next/font and @font-face CSS declarations.
Mobile App Font Assets
Remove font hinting from TTF assets bundled in iOS and Android apps — mobile screens are high-DPI and never use hinting instructions. Stripping hinting reduces APK and IPA bundle size without any visual impact.
GDPR-Safe Self-Hosted Font Preparation
Remove hinting as part of your self-hosted font pipeline before converting to WOFF2 — produces the smallest possible font files for GDPR-compliant self-hosting without relying on Google Fonts or Adobe Fonts CDN.
Electron and PWA Applications
Remove font hinting from fonts bundled in Electron apps and Progressive Web Apps — all modern rendering engines (Blink, WebKit, Gecko) ignore hinting on high-DPI displays, so removing it reduces bundle size with no downside.
Font Distribution and Packaging
Remove hinting when packaging fonts for distribution as npm packages, design system assets, or open-source releases — dehinted fonts are smaller, load faster, and render consistently across all modern operating systems.
Understanding Font Hinting Removal
What is Font Hinting?
Font hinting (also called grid-fitting) is a set of instructions embedded in TrueType fonts that tell the rendering engine how to adjust glyph outlines to align with the pixel grid at small sizes on low-DPI screens. Hinting was critical in the 1990s and 2000s when screens had 72–96 DPI and text at 12px needed manual pixel-level adjustments to remain legible. Modern screens — including all Retina, HiDPI, and 4K displays — render at 144–400+ DPI, where hinting instructions are ignored entirely by the operating system. Our font hinting remover strips these now-redundant instructions from the font binary, reducing file size with no visual impact on any modern device.
How Our Font Hinting Remover Works
- 1Upload your TTF or OTF files: Drag and drop one or more font files onto the drop zone. The files are read as binary data in your browser — no data is sent to any server. Both TrueType (TTF) and OpenType CFF (OTF) fonts are supported.
- 2Click "Remove Hinting": The tool parses the sfnt font structure, identifies hinting tables (cvt, fpgm, prep, hdmx, LTSH, VDMX, gasp), removes them from the table directory, and rebuilds a valid sfnt binary with correct header fields and table offsets.
- 3Download your dehinted fonts: Single files download directly with the same extension (TTF or OTF). Multiple files are packaged into a ZIP archive. The results panel shows which tables were removed and the size reduction for each font.
What Gets Removed During Dehinting
- cvt (Control Value Table): A table of values used by hinting instructions to control stem widths, heights, and other measurements — typically the largest hinting table in complex fonts.
- fpgm (Font Program): Bytecode executed once when the font is first loaded — defines reusable hinting subroutines used across all glyphs.
- prep (CVT Program): Bytecode executed before each glyph is rendered — adjusts CVT values based on the current point size and resolution.
- hdmx, LTSH, VDMX, gasp: Pre-computed device metrics and grid-fitting behaviour tables — all hinting-related and unused on modern high-DPI displays.
Important Limitations
Removing hinting has no visual impact on modern high-DPI screens (Retina, 4K, HiDPI). However, on legacy low-DPI monitors (96 DPI or lower) at small font sizes (below 16px), hinting can improve legibility. If your font is used in print workflows, embedded in PDFs, or displayed on legacy hardware, keep the original hinted version. The font hinting remover preserves all glyph outlines, metrics, kerning, and OpenType features — only the hinting instruction tables are removed.

Frequently Asked Questions About Font Hinting Remover
A font hinting remover is a tool that strips TrueType hinting instructions from font files — specifically the cvt, fpgm, prep, hdmx, LTSH, VDMX, and gasp tables. Our free font hinting remover online works entirely in your browser by parsing the sfnt binary structure. Your font files are never uploaded to any server.
On modern high-DPI screens (Retina, 4K, HiDPI), removing hinting has zero visual impact — these displays render at 144–400+ DPI where hinting instructions are ignored by the OS. On legacy 96 DPI monitors at very small sizes (below 14px), hinting can improve legibility. For web and mobile use, removing hinting is safe.
Absolutely. Our font hinting remover processes everything locally in your browser. Your font files are never uploaded to any server, never stored, and never leave your device. All processing happens entirely on your machine.
Yes — 100% free, forever. No signup, no account, no premium tier, no file size limits, and no ads interrupting your workflow. Just upload your fonts, remove hinting, and download.
The font hinting remover removes seven tables: cvt (Control Value Table), fpgm (Font Program), prep (CVT Program), hdmx (Horizontal Device Metrics), LTSH (Linear Threshold), VDMX (Vertical Device Metrics), and gasp (Grid-fitting and Scan-conversion Procedure). All other tables — including glyph outlines, metrics, kerning, and OpenType features — are preserved.
Typical size reduction from removing hinting is 2–15% depending on how extensively the font was hinted. Heavily hinted fonts like Arial, Times New Roman, and Calibri see larger reductions. Variable fonts and CJK fonts with minimal hinting see smaller reductions. The results panel shows the exact reduction for each font.
No — OpenType layout features (GSUB, GPOS, kern, liga, etc.) are completely separate from hinting tables and are not touched by the font hinting remover. All ligatures, kerning pairs, stylistic alternates, and other OpenType features are fully preserved in the output.
Yes — variable fonts use the same sfnt container structure as static fonts. The font hinting remover strips hinting tables from variable fonts (TTF-based) the same way. Note that variable fonts typically have minimal hinting, so size reduction may be small.
Since processing runs entirely in your browser, the practical limit depends on your device's available RAM. Most modern devices handle font files up to 50 MB without issues. Large CJK fonts with thousands of glyphs process in under a second.
