Frequently Asked Questions
What is WPS Office?
WPS Office is a cross-platform office suite (Windows, macOS, Linux, iOS, Android) that includes a word processor, spreadsheet, presentation tool, and PDF editor. It is popular in Asia and worldwide. The free version includes ads and a watermark on exported PDFs; the premium plan starts around $35/year.
Does WPS Office upload my documents to its servers?
WPS Office offers cloud features via WPS Cloud, which syncs and stores your documents on their servers. Even the desktop version can upload files for cloud processing. SigPDF processes everything locally in your browser — no uploads at any point.
Does WPS Office add watermarks to signed PDFs?
Yes. The free version of WPS Office adds a WPS watermark to exported and saved PDFs, including signed ones. The premium plan removes watermarks. SigPDF never adds watermarks at any plan level.
Is SigPDF cheaper than WPS Office for signing PDFs?
WPS Office premium starts around $35/year (~$2.92/month). SigPDF starts at €2.08/month (annual billing, €24.99/year) — comparable pricing but focused exclusively on private, browser-based PDF signing with no uploads.
Can I use WPS Office without an account?
WPS Office can be used without an account for basic local features, but cloud features require an account. SigPDF allows full preview without any account — a subscription is only required to download the signed PDF.
Which is more private — SigPDF or WPS Office?
SigPDF is significantly more private. Your documents are processed entirely in your browser — no file is ever transmitted to SigPDF. WPS Office, especially with cloud sync enabled, uploads documents to its servers. Even without cloud sync, WPS is a native app that can access your files.
Does WPS Office work in the browser?
WPS Office has a web version (WPS Office Online), but its full PDF editing and signing features are primarily in the desktop and mobile apps. SigPDF works entirely in any browser, on any device, without installation.
