Offers, contracts, references, scanned IDs: a small business lives in PDF files. And most PDF tools now want those files in their cloud before they will do anything. PdfCraft is the opposite — a free, open-source PDF editor that runs entirely on your own computer. No account, no telemetry, no upload: your client documents stay where they belong.

If you have ever dropped a client’s contract into a free online PDF tool just to merge two files, you have met the problem. “Free” web tools usually mean your document travels to a server you know nothing about — sometimes outside Switzerland, sometimes outside Europe. For a notary, a fiduciary or a doctor, that is not a small detail. It is a data-protection decision made in a hurry.

Why the cloud question matters more than it sounds

Under the revised Swiss Data Protection Act, you stay responsible for client data even when a tool processes it for you — and professional confidentiality does not pause because a website promises “files deleted after one hour”. The safest transfer is the one that never happens. A good rule of thumb: if you would not post a copy of a document to a stranger, do not upload it to one either.

That is what makes a local editor interesting. It is not about distrust; it is about defaults. When a tool simply has no way to send your files anywhere, you stop reading privacy policies for routine jobs like merging, splitting or reordering pages.

What PdfCraft does well

PdfCraft is a young open-source project with apps for Windows, macOS and Linux. The everyday jobs it already covers well:

  • Reordering pages: drag pages around like cards — put a signed contract back in the right order before it goes to the client.
  • Merging and splitting: combine a week of scans into one clean dossier file, or split a thick scan into separate documents per topic.
  • Deep undo: changes are saved alongside the original instead of over it, so the bytes of an important file stay intact — a quiet form of insurance.
  • Damaged files: pages are rendered one by one, so a broken scan gets repaired rather than refused.

The program costs nothing, and the source code is public — anyone can check what it does instead of trusting a marketing page.

What it cannot do yet

An honest look includes the limits. Text recognition for scans (OCR) is not built in — you download a separate model first, and only you can judge whether its quality is good enough. Editing existing text inside a PDF is still at an early stage by the project’s own account. And if your daily work depends on professional redaction or qualified electronic signatures, keep your current tool for those jobs.

Take the project’s own numbers with calm as well: statements like “zero crashes on our test corpus” are the developers’ tests, not an independent audit. For routine page work on copies, that is fine. For the only copy of an original document, keep backups — as with any tool.

How to try it safely

  1. Take it from the source. Use the project’s own GitHub releases, not a random download portal that may bundle extra software.
  2. Work on copies first. Give it duplicates of real documents for a week — never the only copy of anything.
  3. Start with one routine. Pick a recurring job, such as merging the week’s scans every Friday, and let the new tool own just that one.
  4. Keep originals untouched. PdfCraft’s append-style saving helps, but your folder discipline matters more than any feature.

The quiet financial upside

There is also a plain cost argument. A mainstream PDF subscription runs roughly 15 to 25 dollars per user per month. For a three-person office, that is several hundred francs a year for tasks a free local tool covers just as well. Nobody has to switch overnight — simply stop paying for the jobs that never needed the cloud in the first place.

Data protection is often mostly a question of which tools you reach for. A local PDF editor will not make headlines, but it removes a whole category of risk from your week — quietly, and for free.
