What you can edit
Add text, signatures, images, checkmarks, crosses, and highlights. Fill supported PDF form fields, search document text, and download your result.
Files you can open
Open one or more PDFs, images, or Word files. Image and Word imports are converted locally to PDF before editing. Complex Word layouts may not convert perfectly, so review the output.
No account or usage meter
The core signing and editing workflow has no account requirement, subscription, or paid tier. Your browser stores the working copy locally; it is not a cloud backup.
Frequently asked questions
Is Sigy free?
Yes. Core PDF signing, filling, annotation, printing, and download are free to use.
Can I edit existing text inside a PDF?
Sigy adds text and annotations and fills supported form fields. It does not rewrite arbitrary existing PDF text.
