Files tools
17 free files tools · PDF and data tools that stay local
Most online PDF tools work by uploading your document to somebody else’s server. These do not — the PDF is opened and rewritten inside the page, which matters when the file is a contract, a payslip or a scan of your passport. Merging, splitting and page organisation keep the text layer intact; the tools that cannot are explicit about it.

Guides
- Why compressing a PDF sometimes makes it bigger PDF compressors shrink scans dramatically but can inflate text documents. The difference is what the PDF stores inside — here is how to tell before you compress.
- Scanned PDF vs text PDF: why you sometimes cannot copy the text Some PDFs let you select and search text, others behave like photos. The difference is the text layer — what it is, how to check for it, and what OCR actually does.
- The two kinds of PDF password (and why one barely protects anything) A PDF can have an open password, a permissions password, or both — and they offer very different protection. What each one does, and what removing them involves.
- MB vs MiB: why a 1 TB drive shows up as 931 GB Drive makers count in powers of 1000, operating systems in powers of 1024. Nobody is lying — the maths behind the missing gigabytes, and what KiB and MiB mean.
