Free BizDocs tools — PDF tools and business calculators
Free BizDocs tool categories
PDF Tools
Merge, split, compress, convert, rotate, watermark, and sign PDFs. Every file is processed on your device — nothing is ever uploaded.
Calculators
Prorated rent, loan payments, overtime, equity splits — business & legal math answered instantly, with the formula and a worked example shown.
Built different from other free tools
No upload queues, no “3 free uses left,” no watermarks stamped on your files.
Your files stay yours
The PDF tools do all their work inside your browser. Files are never uploaded to a server, so there’s nothing to intercept, store, or leak.
Instant, with no signup
No account, no email, no free-trial counter. Open a tool, get your result, download it — the whole thing takes seconds.
Math you can check
Every calculator shows the formula it used and a worked example with real numbers, so you can verify the answer instead of trusting a black box.
Why are these tools free?
BizDocs is a document generator — it writes complete, customized legal and business documents like leases, operating agreements, contracts, and invoices. The jobs people need done around those documents are usually small: merge two PDFs before sending, compress a lease under an upload limit, figure out prorated rent before writing it into the agreement. Charging for those felt wrong, so we didn’t.
The PDF tools handle the file work and the calculators handle the number work. If what you actually need is the document itself, that’s the part BizDocs is built for — browse the document library or start one now.
Common questions
Yes. No usage caps, no watermarks added to your files, no account required. BizDocs makes its money on complete documents — the tools are free because they solve the small jobs around that paperwork.
No. The PDF tools run entirely in your browser. Your files are opened and edited on your own device and never transmitted to BizDocs or anyone else — you can even use them offline once the page has loaded.
No signup, no email, no trial. Open a tool, use it, download the result. An account is only needed if you generate a full legal or business document with BizDocs.
Each calculator shows its formula and a worked example so you can verify the math yourself. They’re estimation tools for planning and drafting — not legal or financial advice.
Tools fix the small stuff.
Documents make it official.
When the quick fix isn’t enough, BizDocs writes the actual lease, contract, or agreement — customized to your situation in minutes.
