Frequently asked questions
Can I convert PDF to an editable Word document?
Yes! Upload a PDF and choose DOCX or DOC. LibreOffice recognizes text, tables, and formatting. Complex layouts may need some manual adjustment.
Is formatting preserved in DOCX → PDF?
Yes, LibreOffice preserves fonts, tables, images, and page layout when converting to PDF.
Can I convert Excel to PDF?
Yes, XLS and XLSX convert directly to PDF with all spreadsheets. You can also convert to CSV for plain data export.
What about password-protected documents?
Password-protected files can't be converted — remove the password in Word/Excel first, then upload.
How long are files stored?
All files are deleted automatically after 1 hour. We never read the content of your documents.
