Are these guides official WhatsApp or government docs?
No. They explain Tokitool workflows and commonly published sizes. Menu names and rules change; confirm with WhatsApp, Passport Seva, GOV.UK, or your issuing authority when it matters.

Guides
Step-by-step articles written for Tokitool’s own tools, not scraped how-tos. Each guide explains a real workflow on this site (export PDF, compress for a form, cover a face without uploading, passport sizing, QR payloads, passwords, privacy checks) so you can finish the job without guessing.

Read articleHow these guides relate to the tools
Tokitool’s tools are intentionally small. The guides sit next to them so you get export steps, size tables, and privacy checks without stuffing every edge case into the tool UI. Start with the article when you are unsure which menu WhatsApp shows, which passport millimetres apply, or whether a “private” converter is actually uploading your file.
Size and type hubs are separate from the long-form guides: use them when you already know the job and need a country, kilobyte target, or QR payload type quickly.
