Sign & fill a PDF — right in your browser
Nothing uploads. Your document stays on this device.
Nothing uploads. Your document stays on this device.
The documents that most often need a signature — a lease, an offer letter, an NDA, a medical form — are also the ones you would least like to hand to an unfamiliar server. The usual workflow makes you do it anyway: upload, wait, download, then hope the copy on the other end is deleted.
SignFit removes that step. It renders the PDF locally and writes your changes back with a PDF library running in the same browser tab. Nothing is transmitted, so there is no copy to delete and nothing to take on trust.
Alongside the signature you can add text anywhere on the page, tick checkboxes, draw freehand and highlight passages. When you download, the additions are flattened into the file so they appear identically in every viewer.
No. There is no server component — the PDF is opened, edited and saved entirely on your own device.
Signing and filling PDFs is free, with no account required.
Not the original text. SignFit adds a new layer on top of the page, which is what keeps the document's fonts and layout exactly as they were.
Yes — the same editor, one click from your toolbar, still running entirely on your device.
