Fix clipped text

On-device

Raise a font's Windows clip box so tall letters and stacked Arabic marks stop being cut off in Word and other Windows desktop apps.

Your fonts are read and fixed in your browser and are never uploaded.

Word and most Windows desktop programs cut every glyph off at two numbers in a font, usWinAscent and usWinDescent, and many fonts have letters or stacked marks — shadda with a vowel on lam-alef, Vietnamese double accents, Quranic signs — that reach past them. This tool measures how far the font really reaches: every glyph's outline, plus the deepest common mark stacks drawn by your browser in the font itself. It raises those two numbers just enough and never lowers them. Before you fix anything it shows how much taller lines will be in Word, because the same numbers set the line height there. Web pages and Mac apps keep their spacing: the font's typographic line metrics are pinned to the old values. It changes the Windows clip box only; it can't fix clipping caused by an app's own line-spacing setting. Each fixed font gets a new family name by default, is checked by your browser's font validator and re-measured before it is offered. Fonts with PostScript (CFF) outlines use an optional one-time engine download to be renamed. Your fonts are never uploaded.

About this tool

What you provide

  • One font file — .ttf, .otf, .woff or .woff2, up to 30 MB — or several at once.

What you get

  • Each font with its Windows clip box (usWinAscent / usWinDescent) raised to its measured extent, in the same format as the input; several fonts download as one .zip.

Limits

  • Only the Windows clip box changes; outlines are untouched and the box is never lowered.
  • Lines get taller in Word and other Windows desktop apps; web pages and Mac apps keep their spacing.
  • Renaming a font with PostScript (CFF) outlines needs the full engine; keeping the name does not.
  • Fonts with an OS/2 table older than version 2, variable fonts whose clip box varies (MVAR), and font collections (.ttc) are not supported.
  • You confirm you have the right to modify the font; the tool does not grant that right.

How to use it

  1. Choose fonts

    Tap “Choose a font file” or drop the fonts that get cut off — .ttf, .otf, .woff or .woff2, one or several.

  2. Check the measurement

    Read how far the text reaches past the current Windows clip box and how much taller lines will be in Word.

  3. Confirm the licence

    Read the font's licence text, tick the box to confirm you may modify it, and keep the new family name or tick to keep the original.

  4. Download

    Tap “Fix clipping”. Once each fixed font passes the checks, download it on its own or all of them as a .zip.

Frequently asked questions

Is my font uploaded?

No. The font is measured and fixed in your browser and the new file is built there. Fonts with PostScript (CFF) outlines that you rename use a one-time engine download from this site; the font itself is never sent to a server.

Why are letters or marks cut off in Word?

Word and most Windows desktop programs cut every glyph off at two numbers in the font, usWinAscent and usWinDescent. When tall letters or stacked marks — for example shadda with a vowel on lam-alef — reach past them, the part outside is not drawn.

What does the fix change?

It raises those two numbers to how far the font really reaches, measured from every glyph's outline and from the deepest common mark stacks drawn in the font, and never lowers them. The outlines are not touched.

Will my line spacing change?

In Word and other Windows desktop apps, lines get taller, because the same two numbers set the line height there — the page shows by how much before you fix anything. Web pages and Mac apps keep their spacing: the font's typographic line metrics are set to the old values.

Does it fix every kind of clipping?

No. It changes the Windows clip box only. Clipping caused by an app's own exact line-spacing setting, or by marks deeper than anything measured, is not something a font change can fix.

Can I keep the original font name?

Yes, if your licence allows a modified copy to keep it — you confirm that with a second tick. OFL fonts with a Reserved Font Name must be renamed. Uninstall the original before installing the fixed copy, then restart the app.
