💡 Tips to avoid font corruption
Always use standard Unicode fonts like Times New Roman, Arial, or Calibri. If using custom fonts, embed them in your document before saving.
Edit visible PDF content safely
The editor is built for quick visual changes: add text, signatures, highlights, stamps, images and cover visible text. It does not reflow the original PDF like a Word processor, so it is best for forms, annotations and small corrections.
- Use overlay text for quick visible corrections.
- Use masking/redaction only for visual hiding, not forensic legal redaction.
- Export and review the final PDF before sharing.
