Is my PDF uploaded to a server?

No. FitPDF processes your documents entirely locally in your web browser. Your files never leave your device.

Will my PDF text remain selectable?

Yes. Unlike tools that rasterize the whole page, FitPDF preserves your text, vector graphics, and links intact.

How to sign a PDF

Choose the PDF you need to complete.
Add text, upload a signature image, or place an ordinary image.
Drag and resize each item, then apply the changes and download.

Clean a photographed signature

FitPDF measures the paper background locally, removes it and keeps the ink so a grey rectangle does not cover the page. You can retain the original ink colour or make it black.

A visible signature is not a cryptographic digital signature. FitPDF will not alter a PDF that already carries a digital signature.
