Troubleshooting Common Issues When AI Changes PDF Text
Even with advanced tools, some PDFs behave differently. Here’s how to fix common hiccups when using AI to change or rewrite text.
Formatting Looks Off After Editing
Use the Edit PDF tool to adjust spacing, fonts, or alignment after AI rewriting. Some PDFs contain embedded styles that need manual tweaks.
Fonts Don’t Match the Original Document
Upload the edited text through Edit PDF, then select the same font style to restore the original look. Embedded fonts sometimes don’t transfer perfectly.
The AI Can’t Select Text From Your PDF
Your file may be scanned or image-based. Use OCR (Optical Character Recognition) first to make the text editable, then apply AI rewriting.
Changes Don’t Appear After Download
Make sure the document was saved or exported correctly before closing. Reapply edits and download again to confirm they’ve been saved.
Keep your file readable, consistent, and ready to share.
AI PDF Editor FAQs
Is there an AI that edits PDFs for you?
Yes, but not in a single click. Smallpdf’s AI can suggest and rewrite text for you through Chat with PDF, then you can apply those updates in the Edit PDF tool. It combines AI-generated changes with manual editing to keep your formatting consistent.
Can ChatGPT modify a PDF?
Not directly. ChatGPT can read text but not change PDFs. To have AI change PDF text, use Smallpdf’s Chat with PDF tool, which edits actual file content online.
What happens with complex layouts or tables?
AI can read and rewrite text from complex layouts or tables, but it doesn’t directly edit those elements in the PDF. After getting your rewritten text from Chat with PDF, open the file in Edit PDF to manually replace the content and adjust spacing or alignment where needed.
Does AI editing affect fonts and formatting?
AI doesn’t directly modify fonts or layouts inside the file. It provides rewritten text that you can copy and insert using Edit PDF. Once added, adjust the font, size, or spacing to match your original document.
What if the AI doesn’t detect my text?
That usually means your PDF is image-based. Use OCR first to convert it into an editable format, then open it with Chat with PDF to have AI rewrite or extract the text before applying changes in Edit PDF.
Is it safe to use an AI PDF editor?
Yes. Smallpdf uses TLS encryption, automatic file deletion within 60 minutes, and GDPR-compliant servers to protect your data.
