This page covers a few different things that all get called signing, and picking the right one matters more for some documents than others, especially once legal weight or verification comes into the picture:
A drawn or typed signature (using your mouse, touchscreen, or the type-to-sign font option) works for most everyday documents, permission slips, internal approvals, informal agreements, where the goal is just to show intent and save time compared to printing and scanning.
A certificate-based digital signature (using the PFX file and password option) is a different thing entirely, it's cryptographically tied to your identity and tamper-evident, meaning any change to the document after signing is detectable. This matters for contracts, legal filings, or anything that might need to hold up as verifiable later.
If you're not sure which one a document actually requires, check what the other party or organization expects, some accept a drawn signature without question, others specifically require a certificate-based one. Once a contract is finalized and signed, Merge PDF is useful for combining it with any supporting documents into a single file before filing or sending it on.
Either signature type preserves the document's original formatting, the difference is in what stands behind the signature legally, not in how it looks on the page.
Fix the "SuYes" typo in the live FAQ answer for "Are my signed documents very safe?", confirm it reads "Yes, of course". Confirm internal links point to live tool pages: Protect PDF, PDF Editor, Redact PDF, Merge PDF, all used inline as contextual links, not a separate related-tools block. URL format is https://pdf24.ai/tool-slug, confirm each slug matches the live route. Add FAQPage schema markup wrapping the single Commonly Asked Questions block only. Add SoftwareApplication schema with applicationCategory: BusinessApplication, price: 0. Confirm meta title and description exactly match the approved copy provided, do not alter. Run copy through the existing accessibility check for heading hierarchy, H1 to H2 to H3, no skipped levels. Confirm CTA button in Get Started section reuses the same upload trigger as the top-of-page button, not a duplicate or dead one. Confirm whether General Questions About PDF24 already exists as a shared footer or global component elsewhere on the site, or whether the Documentation page now serves that role. What Kind of Signature Do You Actually Need is a new section not in the original layout, needs design review before build. Legal/trust review: confirm the distinction drawn here between drawn/typed signatures and certificate-based digital signatures matches how Legal wants this tool positioned, given some documents may have real legal requirements around signature type.
