Your signature
How it works
- Choose your PDF.
- Draw, type, or upload your signature and click Use this signature.
- Click where it goes, add the date, and download.
Free signing without the catch
Most free e-sign tools limit you to a few documents a month, add their branding, or keep a copy of your file. This one runs entirely in your browser: there is nothing to sign up for, nothing is stored on a server, and the downloaded PDF carries only your signature.

FAQ
Does my data get uploaded or stored?
No. Processing runs entirely in your browser. Structura does not upload your files for processing and does not keep file contents on a server. Closing the tab clears the in-memory copy.
Is processing private / local-only?
Yes for the tool’s job. Your files stay on the device. Optional Cloudflare Web Analytics may record page views and anonymous events such as tool runs and downloads, never file contents or file names.
Is it really free?
Yes, with no limit on documents and no watermark.
Do I need to create an account?
No.
Do I need an account?
No. All Structura tools are free to use without signup.
