Fix Hebrew Text and Equations Inserting Incorrectly in PDF
Question details
The user is experiencing formatting errors where new text is inserted on the wrong side of the sentence when editing a PDF that contains right-to-left Hebrew text and mathematical equations.

- Scenario
- Modifying sentences or correcting data inside a PDF document that combines right-to-left language structures with standard mathematical equations.
- Observed behavior
- Adding or modifying text causes new characters to be placed on the incorrect side of the sentence due to bidirectional text rendering conflicts in the PDF format.
Check if you have access to the original source file (such as a Word, LaTeX, or InDesign document), as directly editing complex bidirectional text in a compiled PDF often breaks the visual layout.
Edit the Original Source File and Re-export to PDF
The most reliable way to handle complex bidirectional text and equations without formatting errors is to modify the source document rather than the PDF.
PDF files are designed as a final delivery format and do not natively manage bidirectional text flow (like Hebrew mixed with equations) as well as word processors do. Editing the source file ensures the structural integrity of your document.
Find the original .docx, .indd, or .tex file that was used to generate the PDF.
Launch Microsoft Word, InDesign, or your LaTeX editor and open the source file.
Modify the Hebrew text or equations as needed, ensuring the right-to-left paragraph direction remains properly configured.
Once edits are complete, go to File > Save As (or Export) and choose PDF to generate a clean, correctly formatted document.
Convert the PDF to Word for Editing
If you do not have the source file, converting the PDF to a Word document allows you to fix the text direction natively before saving it back as a PDF.
Use WPS Office to Convert and Edit Complex PDFs
WPS Office offers powerful PDF conversion and document editing tools. Easily convert complex PDFs containing Hebrew text and equations into editable Word documents, fix the bidirectional text flow natively, and export them back to pristine PDFs.
- 1. Open PDF to Word Tool: Launch WPS Office and click on 'PDF to Word' from the toolkit menu.
- 2. Convert your PDF: Import your PDF file containing the Hebrew text and click 'Start' to convert it into an editable Word document.
- 3. Edit with RTL Support: Open the converted file in WPS Writer, set your paragraph direction to Right-to-Left, and modify your text and equations cleanly.
- 4. Export as PDF: Go to Menu > Export to PDF to save your corrected document back into a fixed PDF format.
Frequently Asked Questions
Why does my text type backwards when editing Hebrew in a PDF?
PDFs often lack the underlying structural data for bidirectional text flow. When you attempt to type, the PDF editor defaults to a standard left-to-right input mode, which causes right-to-left languages like Hebrew or Arabic to appear backwards or be placed incorrectly.
Can I edit mathematical equations directly inside a PDF?
Most standard PDF editors treat equations as grouped vector shapes or images rather than editable text strings. To edit them properly without breaking the formatting, you usually need to alter the source file or convert the PDF to a Word document first.
Is there a way to force right-to-left typing in my PDF editor?
Some professional PDF editors include specific paragraph settings for Right-to-Left (RTL) text direction. You will need to check your editor's text formatting toolbar for an RTL icon and activate it before attempting to insert new Hebrew text.
