3. DownloadGet your filled, signed PDF instantly. No watermark, no paywall, no email required.
Why is FillSign free when others charge $96/year?
Most online PDF fillers upload your document to their servers, let you fill in the whole form, and only then reveal that downloading costs money. Running servers is expensive, so they need subscriptions. FillSign does all the work inside your browser instead — there are no servers processing your files, so there's almost nothing for us to pay for, and nothing for you to pay for. Core filling and signing will stay free.
Is it safe for sensitive documents?
Safer than any upload-based tool, by design. Tax forms, leases, medical forms, contracts — your file is opened and edited locally on your device, exactly like a desktop app. If you turn off your internet connection after the page loads, FillSign keeps working. That's the proof.
