How to: Convert to PDF
- Select files of any supported type (or a ZIP).
- Choose one combined PDF or one PDF per file.
- Download the result.
Mixed bundles of documents – a Word letter, a spreadsheet, a few photos – usually need three different converters. FreePDF converts them all in one step in your browser and can merge them into a single PDF with a bookmark for each original file, so the result is easy to navigate. ZIP archives are unpacked automatically.
Common uses
- Bundle application documents (CV, certificates, photos) into one PDF.
- Convert a whole folder of receipts from a ZIP.
- Turn spreadsheets into printable PDF tables.
- Archive mixed project files as PDF.
Tips for best results
- Tick 'Sort files by name' when files are numbered (1, 2, 10 sort naturally).
- Choose 'One PDF per file' for separate conversions in a ZIP.
- Complex Word layouts convert best with our dedicated Word to PDF tool.
