PDF Converter Download Guide

Online converters are convenient and require no installation, but they upload your file to a remote server. That's fine for a public flyer, but a poor choice for contracts, tax forms, or anything confidential. Offline desktop converters keep everything on your machine, which matters for privacy and for working without an internet connection.

If you handle sensitive documents regularly, install a desktop converter. For the occasional one-off conversion of non-private files, a trusted web tool is perfectly reasonable.

Before downloading a converter, check what is already on your computer:

• Microsoft Word (2013 and later): open a PDF with File, Open and Word converts it into an editable document using a feature Microsoft calls PDF Reflow. Microsoft says results are best with mostly text documents such as legal and business papers, and that content can shift position because the feature favours editability over exact layout.
• LibreOffice: free and offline, it opens many PDFs for editing and exports any document to PDF; see our LibreOffice download guide.
• Print to PDF: Windows and macOS can both print almost any document to a PDF file, which covers the "document to PDF" direction without extra software.

If these cover your needs, you avoid installing another program altogether. Download a dedicated converter when you need batch conversion, OCR, or PDF to Excel with complex tables.

A scanned PDF is a picture of text, not text. A normal converter will hand you an image inside a Word file, and Word's PDF Reflow cannot read it either. You need a tool with optical character recognition (OCR), which recognises the letters and rebuilds them as editable text. Check the OCR language settings match your document, scan at a decent resolution, and proofread the result, because OCR mistakes such as 0 for O or 1 for l are common. For turning PDF pages into JPG or PNG images instead, our image converter guide lists suitable tools.

Conversion is reconstruction, so spend two minutes checking the output before you send it on:

• Compare page count and headings with the original.
• Check tables, numbers and dates, especially after PDF to Excel.
• Look for missing fonts, odd line breaks and images that moved.
• Search for a few words to confirm the text is real text, not an image.
• Keep the original PDF until the converted file is final.

For reading and annotating rather than converting, a PDF reader is often enough; see our PDF reader download guide and our roundup of the best PDF tools for 2026.

The hardest part of PDF conversion is preserving layout. Simple text documents convert almost perfectly, but complex pages with columns, tables, and embedded fonts can shift around. Tools with optical character recognition (OCR) can also pull text out of scanned image PDFs, which a basic converter cannot.

• For editable text, PDF to Word (.docx) usually gives the best results.
• For data, PDF to Excel works well if the source tables are cleanly structured.
• For scanned documents, choose a converter with OCR support.

Some of the best value comes from full office suites and PDF tools that include conversion as one feature among many. LibreOffice, for example, opens many PDFs and exports to PDF natively, and it's completely free. PDF24 and similar toolkits bundle conversion, merging, splitting, and compression in one package.

The PDF space is crowded with lookalike sites and aggressive ads. Type the official domain directly or use the verified links below. Watch out for fake 'Download' buttons inside ad banners. During installation, decline optional browser extensions, search-engine changes, and bundled apps. Run a quick malware scan on any installer if you're unsure.

If you convert files regularly, look for batch processing, which lets you drop a whole folder of PDFs and convert them in one pass. Power users on Windows, macOS, and Linux can also script conversions with command-line tools like Ghostscript or Pandoc, though those have a steeper learning curve.
