Looking for alternatives to online PDF converters? Many users reach for tools like ILovePDF or Smallpdf to convert, compress, or extract text from PDFs. But uploading sensitive documents to third-party services isn't ideal — and paying per file defeats the purpose of "free."
Here are the best alternatives for PDF conversion, most of them processing files locally on your device.
ConvertForge — Extract Text From PDFs Without Upload
Best for: Converting scanned PDFs to searchable text, privacy-conscious users
ConvertForge is a Chrome extension that runs PDF-to-text conversion entirely in your browser using local OCR. No file is uploaded to any server. Paste a PDF, extract text instantly, and get a .txt or .docx file back. Works offline once installed.

LibreOffice — Best for PDF Editing and Export
Best for: Creating PDFs, converting DOCX/XLSX to PDF
LibreOffice can open PDFs, edit them, and export documents back to PDF without any online service. Free, open-source, and runs on Windows, Mac, and Linux. Trusted by enterprises.
Limitation: Not ideal for batch conversion of dozens of files.
FFmpeg — Extract Audio From PDF Videos
Best for: Converting video or audio embedded in PDFs
FFmpeg handles multimedia conversions from the command line. If your PDF contains embedded video or audio, FFmpeg can extract it. Free and open-source, but requires a terminal.
PDFtk — Command-Line PDF Manipulation
Best for: Splitting, merging, rotating pages
PDFtk handles structural PDF operations entirely offline. Free and lightweight, but command-line only.
