Frequently Asked Questions — Chat to PDF Converter

No — and this is the most important thing to understand about CHATS2PDF. All conversion runs 100% inside your browser using JavaScript. Your chat files are never sent to any server. The tool pages enforce a strict Content-Security-Policy header that sets connect-src: 'none' — this technically blocks all outbound network connections, not just by policy but at the browser level. Your messages cannot leave your device.

No. We do not store, sell, broker, or share your chat content. Our architecture makes it technically impossible — files processed in the browser never reach our servers. There is nothing to sell or share even if we wanted to.

No. There is no account system on CHATS2PDF. You can start converting immediately without registering, verifying an email address, or agreeing to a data-sharing policy. There is nothing to sign up for.

No analytics scripts, no advertising cookies, no tracking pixels. CHATS2PDF does not use Google Analytics, Facebook Pixel, or any third-party tracking service. The only browser storage used is sessionStorage for optional notes autosave — this is cleared when you close the tab.

Yes — the browser-local architecture is specifically designed for sensitive use cases. However, you are responsible for your device's physical security, your browser's security, and ensuring the generated PDF is handled appropriately after download. We recommend using a private/incognito browser window for maximum privacy.

Yes. Completely free, with no limits, no subscription, and no paid tier. All 24 conversion tools are available at no cost. If you find the tool valuable, donations help keep the project alive and updated.

CHATS2PDF currently supports: Telegram, WhatsApp, Messenger, Instagram DM, iMessage, Discord, Signal, Gmail MBOX, Snapchat, WeChat, Douyin, Screenshot to PDF, and Archive ZIP to PDF. See all tools →

Yes. Generated PDFs can be printed, emailed, shared, archived, or submitted — there are no watermarks, no DRM, no restrictions. The PDF belongs entirely to you once it's downloaded.

There are no artificial limits. However, very large exports (100,000+ messages) may take a few seconds to process and may produce large multi-page PDFs. The Gmail MBOX converter lets you select up to 50 emails per batch for manageable output.

Yes. CHATS2PDF is a responsive web app that works in any modern mobile browser (Safari, Chrome, Firefox) on iOS and Android. The converter tools are fully functional on mobile, though the file upload flow may differ slightly depending on your device.

Open the WhatsApp conversation → tap the three-dot menu (⋮) → More → Export Chat → choose Without Media. This creates a .txt file you can upload to the WhatsApp to PDF converter. On WhatsApp Web, the process is similar via the chat settings menu.

In Telegram Desktop: Settings → Advanced → Export Telegram Data. Select the chat or channel you want, choose JSON format (recommended), and click Export. The result is a result.json file ready for the Telegram to PDF converter.

Go to Facebook Settings → Your Facebook Information → Download Your Information. Select Messages, choose JSON format, and request the download. Once ready, upload the messages JSON file to the Messenger to PDF converter.

Visit takeout.google.com. Deselect everything, then select Mail only, choose .mbox format, and export. Download the resulting ZIP and extract the .mbox file, then upload it to the Gmail MBOX converter.

For your personal data: Discord Settings → Privacy & Safety → Request all of my Data. Discord emails you a download link within 30 days. For server/channel exports, use the open-source DiscordChatExporter tool to generate a JSON file, then upload to the Discord to PDF converter.

No. Legal admissibility depends entirely on your jurisdiction, applicable court rules, chain-of-custody requirements, and authentication standards. A PDF generated by a browser tool is not inherently authenticated or certified. Always consult a qualified legal professional before relying on any converted document in formal legal or regulatory proceedings.

You are. You are solely responsible for: lawful access to the original chat data, consent from other parties in the conversation, the downstream use of generated PDFs, and compliance with all applicable laws in your jurisdiction. CHATS2PDF disclaims all liability for misuse. See the full disclaimer.

No. CHATS2PDF is an independent tool. It is not affiliated with, endorsed by, licensed by, or connected to Telegram, WhatsApp, Meta (Messenger/Instagram), Google (Gmail), Apple (iMessage), Discord, Signal, Snapchat, WeChat, Douyin, or any other platform mentioned on this site.

This depends on your jurisdiction and the purpose of the conversion. In many places, recording or preserving conversations without all-party consent may have legal implications. CHATS2PDF does not provide legal advice on this question — consult a qualified lawyer in your jurisdiction before converting conversations you do not solely own.

The most common causes are: (1) using a non-official export file (renamed or edited files may fail validation), (2) wrong format for the tool selected (e.g. uploading a WhatsApp ZIP to the Telegram tool), or (3) a corrupted or partial export file. Use the official export function for your platform and retry. If the problem persists, contact us.

CHATS2PDF uses a hand-rolled PDF 1.4 builder written entirely in JavaScript. There is no third-party PDF library dependency. The builder writes raw PDF object syntax, streams, and an XREF table directly — this keeps the tool lightweight, private, and free from supply-chain risk.

CHATS2PDF is built and maintained by a small independent team in Canada. Hosting is on a standard static web server. All computation happens in your browser — the server only delivers HTML, CSS, and JavaScript files.

Yes, mostly. Once the page has loaded (HTML, CSS, JS, and fonts), conversion itself requires no internet connection — it runs entirely in JavaScript. However, Google Fonts will not load if you are offline (the page will fall back to system fonts).
