Frequently asked questions
Does the PDF stay open while I edit?+
Yes. Once your PDF is loaded, you can keep editing in the browser editor, moving text, images, signatures, and initials before downloading.
Can I sign a PDF without uploading it?+
Yes. Signature generation and placement happen fully in your browser, so the PDF never leaves your device.
Can I add initials too?+
Yes. You can add separate initials marks and move them independently from your full signature.
Are my original files modified?+
No. CalmPDF always creates a new edited PDF for download and leaves your original file untouched.
