Sign a PDF online for free without installing Adobe

Most of the time I just need a signature image on a form, not full DocuSign workflow.

What I look for:

1. Upload in the browser
2. Place signature / initials
3. Download without creating an account

I use FileLumo eSign PDF for that kind of quick sign. For dates or cover boxes on the same file, PDF Editor works without a login wall.

Honest limit: this is fine for everyday forms. For legally binding multi-party contracts, use a proper e-signature platform with audit trails.

If the portal also rejects file size, compress after signing: Compress PDF.
