PDF Tools for Freelancers Managing Their Own Invoices and Contracts

Freelance work involves a steady trickle of small document tasks — an invoice here, a signed agreement there — that rarely justify paying for dedicated software, but still need to look professional and stay secure.

Sending invoices

GST Invoice Generator builds a proper invoice with tax calculated automatically, which is usually all a freelancer needs without subscribing to full invoicing software built for teams.

Turning proposals into shareable PDFs

A proposal or contract drafted in Word should usually go out as a PDF so it doesn't reflow or shift formatting on the client's end — Word to PDF handles that conversion directly. If a proposal needs a cover page combined with supporting documents, Merge PDF puts them together into one file.

Protecting signed agreements

Once a contract is signed, Encrypt PDF adds a real password before it's stored or forwarded — worth doing for anything with payment terms or personal details on it.

Keeping files small for client portals

Some client portals and project-management tools cap upload sizes tightly. Compress PDF gets a file under those limits in a few seconds without a subscription-only "pro" feature gate.

FAQ

Is there a cheaper "starter" tier that limits how many invoices I can make? No — there's only one tier, and it's free with no usage limit.

Do I need to install anything, or does this run in the browser? Everything runs in the browser — no installation, and it works the same on any device you're working from.

Can I use this for client work, or is it personal-use only? There's no license restriction of any kind — use it for any purpose, including client and commercial work.
