What Sign PDF does

Use Sign PDF to choose one PDF, draw, type, upload, resize, and place a visual signature. This creates a visible signature mark locally; it is not a certificate-backed digital signature or timestamped identity proof. Filozy starts the document engine only after you choose a file, performs the work inside this tab, and creates a new result for you to save. Your selected document, its filename, and its contents are not sent to Filozy.

Essential questions

Does Sign PDF upload my file?

No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.

Will this change my original file?

No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.
