SignDrop vs Adobe Acrobat
Sign PDFs without an Acrobat subscription
The honest answer: Adobe Acrobat is a full PDF suite — editing, converting, OCR, and its Fill & Sign tool. If you work with PDFs all day, the subscription earns its keep. If you open Acrobat twice a year to sign something, SignDrop does that one job free, in your browser, without the download or the account.

Acrobat is the right tool if you:
- Edit PDFs properly — rearrange pages, convert formats, OCR scanned documents
- Already pay for Creative Cloud (you may have Acrobat included)
- Need Acrobat Sign’s managed send-for-signature workflows for business
SignDrop is the right tool if you:
- Just need your signature, a date, or a line of text on a PDF
- Don’t want a subscription, a desktop install, or an Adobe account for that
- Want the document to stay on your device instead of Adobe’s cloud
- Want to sign with your finger — QR code to your phone, no app
How SignDrop works
- Open a PDF in Chrome (or upload one in the SignDrop popup)
- Draw, type, or upload your signature — or scan a QR code and sign with your finger on your phone
- Download the signed PDF — it never leaves your device
Common questions
Can SignDrop edit PDFs like Acrobat?
No. SignDrop adds signatures, names, dates, text, and drawings on top of a PDF. It doesn’t rearrange pages, convert formats, or OCR. If you need real PDF editing, Acrobat genuinely is the better tool.
Is there really no cost?
None. No trial, no watermark, no per-document limit. SignDrop is a free Chrome extension.
Does it work with scanned PDFs?
Yes — any PDF that opens in Chrome can be signed, including scans. You place your signature visually, exactly where it belongs.
