Product
Adobe InDesign and Acrobat
Device & OS
not provided
Scenario
Attempting to run the form creation tool on a newly exported PDF document.
Observed behavior
The system halts the process and displays a 'Bad PDF' error or flags an unsupported Type 2 or Type 0 font.
Before you start

Identify all the fonts currently used in your source document and verify whether any of them are legacy PostScript, Type 0, or Type 2 fonts.

Solution 1Recommended

Replace PostScript Fonts with TrueType Fonts

Using TrueType fonts ensures maximum compatibility when generating interactive forms, resolving the parsing error.

PDF form processors often struggle with legacy Type 2 or Type 0 PostScript fonts. Replacing them with universally supported TrueType or TrueType-based OpenType fonts allows the document to be processed correctly.

1
Locate Problematic Fonts

Open your original document in InDesign or your preferred layout software. Use the 'Find Font' or font management tool to identify any Type 2, Type 0, or PostScript fonts.

2
Switch to TrueType

Select the text utilizing the unsupported font and replace it with a visually similar TrueType (.ttf) or TrueType-based OpenType font.

3
Embed and Export

Navigate to your export settings. Ensure the option to fully embed all fonts is checked, then export the document as a new PDF.

4
Create the Form

Open the newly exported PDF in your form creator and run the 'Create Form' tool to verify that the error is resolved.

Replace PostScript Fonts with TrueType Fonts
Export Successful: Your PDF will now successfully process into an interactive form without triggering font encoding errors.

Frequently Asked Questions

What does the 'Bad PDF; error in processing fonts' message mean?

This error indicates that the PDF form creator encountered a font encoding structure it cannot parse. This typically happens when the document contains legacy PostScript, Type 0, or Type 2 fonts.

Are OpenType fonts supported in PDF forms?

OpenType fonts that are based on TrueType are universally well-supported. However, OpenType fonts based on PostScript structures may still trigger unsupported font errors depending on the PDF processor.

Can I simply embed the fonts to bypass this error?

No, simply embedding the font is not enough if the font format itself is fundamentally incompatible with the form creation tool. The most reliable approach is replacing it with a standard TrueType font prior to exporting and embedding.
