PDF is the world's most common document format, yet editing and converting them often requires expensive software. The good news: in 2025, you can do almost everything with free browser-based tools. Here's what you actually need.
When you need it: Your PDF is too large to email, or a portal has a file size limit. This is the single most useful PDF tool for most people.
What to look for: Real compression (40–80% for image-heavy files), not just metadata stripping. The best free tools use Ghostscript — a professional-grade PDF engine — to re-encode embedded images.
Use: TurboConvert Compress PDF — powered by Ghostscript WebAssembly, runs entirely in your browser. Three quality levels from 72 DPI (maximum compression) to 300 DPI (print quality).
When you need it: You have multiple PDF files — invoices, contracts, scanned pages — that need to go into one document.
What to look for: Drag-to-reorder so you can control page order, no file size limit, and ideally browser-based processing so confidential documents never leave your device.
Use: TurboConvert Merge PDF — unlimited files, drag to reorder, browser-based.
When you need it: You need just a few pages from a long PDF — an invoice buried on page 5, or one chapter from a 200-page report.
What to look for: The ability to specify exact page ranges, not just "split into equal parts".
Use: TurboConvert Split PDF — extract a range or split into individual pages.
When you need it: You need to edit a PDF document. The PDF format isn't designed for editing, so the best approach is to convert it to Word first.
What to expect: Works best with digital PDFs (text you can select and copy). Scanned PDFs require OCR and results are less predictable.
Use: TurboConvert PDF to Word.
Two more tools that come up constantly:
Most free PDF tools upload your file to their servers for processing. This works fine for most documents, but is worth thinking about for confidential files — contracts, financial documents, medical records.
TurboConvert processes everything in your browser using WebAssembly. Your PDF never leaves your device. This is the same level of privacy as desktop software, with the convenience of a web tool.
