Frequently Asked Questions
Do I need Adobe Acrobat to sign PDFs on Mac?
No. SigPDF works entirely in Safari, Chrome, or Firefox on your Mac. No Adobe Acrobat, no Adobe ID, no installation required. Open SigPDF in any browser and start signing immediately.
Is SigPDF better than Mac Preview for signing PDFs?
For many use cases, yes. SigPDF lets you type your name with handwriting fonts (useful when trackpad drawing feels imprecise), add text fields and dates alongside your signature, batch sign multiple PDFs, and upload an existing signature image. Preview is fine for a quick basic signature if you already have one saved.
Does SigPDF upload my PDF to a server?
No. SigPDF processes your PDF entirely in your browser using client-side JavaScript. Your files never leave your Mac. This makes it a more privacy-friendly option than cloud-based tools like Adobe Sign.
Which Mac browsers does SigPDF support?
SigPDF works in Safari, Google Chrome, Mozilla Firefox, Brave, Microsoft Edge, and Opera on macOS. Any modern browser that supports JavaScript will work.
Can I sign PDFs on a MacBook with a trackpad?
Yes. You can draw your signature using the MacBook trackpad. Many users find the typed name option (with handwriting fonts) produces a cleaner result than trackpad drawing. You can also upload a scanned signature image.
Does SigPDF work on older Macs?
SigPDF works on any Mac running macOS 10.14 (Mojave) or later with a modern browser installed. If your browser is up to date, SigPDF will work.
How much does SigPDF cost on Mac?
SigPDF costs from €2.08/month billed annually. Adobe Acrobat Pro costs €23.99/month. For users who only need to sign PDFs, SigPDF is significantly cheaper with no installation required.
