No Download, No Installation, No Waiting

Adobe Acrobat Pro is a desktop application that requires downloading roughly 1 GB of software, creating an Adobe ID, and going through an installation process. If you are on a work computer with restricted permissions, a Chromebook, or simply want to sign a PDF right now, that is a barrier. SigPDF works instantly in any modern browser — open the page, drop your PDF, place your signature, and download. The entire process takes seconds, not minutes.

Price: €2.08/month vs €23.99/month

Adobe Acrobat Pro costs €23.99/month on an annual plan, which makes sense if you use its full range of features — editing PDF text, creating forms, running OCR on scanned documents, and redacting sensitive content. But if your primary need is adding a signature to PDF documents, you are paying for a lot of functionality you do not use. SigPDF costs €2.08/month and is focused entirely on making PDF signing fast and simple.

When Adobe Acrobat Is the Better Choice

  • You need to edit PDF text, images, or pages
  • You need to create fillable PDF forms
  • You need certificate-based digital signatures (PKI) for government or regulated workflows
  • You need OCR on scanned documents
  • You need to redact sensitive information

When SigPDF Is the Better Choice

  • You just need to sign PDFs — quickly and privately
  • You want no installation, no Adobe ID, no overhead
  • You are on a Chromebook, tablet, or restricted work PC
  • You want to pay €2.08/month instead of €23.99/month
  • You need to sign on mobile without a separate app

Frequently Asked Questions

Can I use the free Adobe Reader to sign PDFs?
Adobe Reader (the free version) does have a basic Fill & Sign feature. However, it still requires downloading and installing the application and creating an Adobe ID. SigPDF requires neither — it works directly in your browser with no installation and no account.
Are SigPDF signatures legally valid?
Yes. Electronic signatures created with SigPDF are legally recognized under the US ESIGN Act and the EU eIDAS Regulation for standard documents like contracts, agreements, and consent forms. Adobe Acrobat additionally supports certificate-based digital signatures (PKI), which may be required for certain government or highly regulated workflows.
Does SigPDF work on Chromebooks?
Yes. Since SigPDF runs entirely in the browser, it works on Chromebooks, tablets, and any device with a modern web browser. Adobe Acrobat Pro does not run natively on ChromeOS.
Can I edit PDF text with SigPDF?
No. SigPDF is focused on signing — adding signatures, text annotations, dates, and images to PDFs. If you need to edit the original text or images inside a PDF, Adobe Acrobat Pro is the right tool for that job.
How much does SigPDF cost compared to Adobe Acrobat?
SigPDF costs from €2.08/month billed annually. Adobe Acrobat Pro costs €23.99/month on an annual plan — more than 10x more expensive. If your primary need is signing PDFs rather than full PDF editing, SigPDF is the more cost-effective choice.
Does SigPDF require an Adobe ID or any account?
No. You can open SigPDF in any browser, upload a PDF, and sign it without creating an account. A subscription is only required to download the signed document. There is no Adobe ID, no registration, and no email verification.
What signature methods does SigPDF offer?
SigPDF offers three ways to create your signature: draw with your mouse, trackpad, or finger; type your name and choose from handwriting-style fonts; or upload an image of your existing signature. Adobe Reader offers similar options in its Fill & Sign tool.
