Privacy-First Architecture: No Uploads, No Tracking, No Account
CHATS2PDF was designed from day one to be the most private chat-to-PDF tool available. Here's how we achieve that technically:
Browser-local processingAll parsing, formatting, and PDF generation runs in JavaScript inside your browser tab. No server ever receives your file.
CSP: connect-src noneA strict Content Security Policy blocks all outbound network connections from tool pages — verified at the browser level, not just by policy.
Web Worker file parsingLarge files like Gmail MBOX are handed to a dedicated Web Worker thread, keeping the main page responsive and the parsing isolated.
No cookies, no analyticsCHATS2PDF does not use cookies for tracking, does not embed analytics scripts, and does not sell or share your usage data.
Session-only autosaveOptional notes typed in the converter are saved to sessionStorage — cleared the moment you close the browser tab.
No sign-up, everThere is no account system. You cannot sign up even if you wanted to. No email, no password, no data profile.
PDF Output Quality and Structure
Every PDF generated by CHATS2PDF follows a clean, readable format designed for archiving, printing, and professional review.
Hand-built PDF enginePDFs are generated entirely in JavaScript using the raw PDF 1.4 specification — no third-party library, no external service, no dependency.
Multi-page supportLarge exports automatically paginate across as many pages as needed. A page header shows the title and page number on each page.
Timestamped coverEach PDF includes a generation timestamp and platform label on the first page for traceability.
Clean typographyHelvetica body text, 10.5pt size, 15pt line height, with 48px margins — optimized for both screen and print at A4 and US Letter sizes.
Word wrap & line breakingLong messages and URLs are automatically word-wrapped at 92 characters per line so nothing overflows the page.
No watermarks or brandingThe generated PDF contains no CHATS2PDF watermarks, logos, or advertisements. It's a clean document that belongs entirely to you.
