TweakPDF

PDF font not available? How to edit the text anyway

You open a PDF in Acrobat or another editor, click a word to fix it, and get told the font is not available, or the new letters come out in a different typeface. The font is in the file, just not in a form those programs can type with. TweakPDF types with the font embedded in the PDF itself, so you can change the word without finding and installing anything.

Why the font is "not available"

To keep files small, a PDF usually carries only part of each font: the letters the document uses, called a subset. Acrobat lists such fonts as Embedded Subset under File > Properties > Fonts.

Desktop editors type new text with fonts installed on your computer, or with a font the PDF carries in full. A corporate typeface, a font from a design app or a subset that lacks the letters you need leaves them with nothing to type with, so they warn you or switch to a substitute such as Arial or Helvetica.

The usual workarounds, and what they cost

  • Install the font

    It works if you can find and license the exact font and version the document used, which is often a paid corporate or designer typeface.

  • Accept the substitute

    The edit goes through in Arial or Helvetica. The changed word looks different from the rest of the line.

  • Cover and retype

    A white box and a text box on top. The font rarely matches, and the old word stays in the file.

  • Edit the source file

    The cleanest fix when you have the original document and the fonts it was made with.

How TweakPDF avoids the substitute

TweakPDF draws the new text with the font embedded in the PDF, at the same size and color, on the same line. You do not need the font on your computer, and nothing is installed.

If a subset lacks a letter you typed, TweakPDF first looks for it in another copy of the same font inside the document. Only a character the file truly lacks is set in the closest matching font, and the preview tells you so before you download, so you can choose a different wording if you prefer.

When there is no font at all

A scanned page is a picture, so there is no font in the file to reuse. Draw a frame over the old text: TweakPDF fills the area from the paper around it, picks the typeface, size and weight closest to the printed letters, and draws the new text into the image.

How to edit a PDF when the font is not available

  1. 1

    Open the PDF

    Drop the file on this page or press Choose file. It opens in the browser; the fonts come from the PDF, not from your computer.

  2. 2

    Click the word and type

    Click the text you want to change, type the new text and press Save. Show text highlights which words can be edited.

  3. 3

    Check the preview

    Press Preview & download. If a character had to come from a similar font, the preview says so. Then sign in with Google and download.

Questions about missing PDF fonts

Why does my PDF editor say the font is not available?
Because the font is not installed on your computer and the PDF carries only part of it, or none of it. Desktop editors need the font installed, or embedded in full, to type new text with it.
Do I need to install the font to edit the PDF?
Not with TweakPDF. It types with the font embedded in the PDF itself, so there is nothing to find, buy or install.
What if a letter I need is not in the PDF?
TweakPDF looks for it in other copies of the same font in the document. If none has it, that character alone is set in the closest matching font, and the preview warns you before you download.
How do I see which fonts a PDF uses?
In Acrobat or Acrobat Reader, open File > Properties and the Fonts tab. Embedded Subset means the file carries only the letters it uses.
Can I change the text to a different font?
No. TweakPDF keeps the font that is already there. To restyle a document, change the font in its source file and export a new PDF.
Is it free?
Yes, 3 files a month are free. You edit and preview without an account and sign in with Google only to download. Pro costs $6 a month for up to 1000 files.

Edit it in the font it already has
