Export text messages and chats as searchable PDF, CSV, HTML, TXT, PNG, or RSMF files while keeping names, visible dates, message order, attachments, and source context together. TextTrace helps you save, print, search, organize, and share important conversations. Prepare records for a lawyer, court review, HR, business documentation, personal archives, or preserving meaningful messages. BRING IN THE SOURCE YOU HAVE • Import a WhatsApp Export Chat TXT or ZIP file, including referenced media when available • Add screenshots or a scrolling screen recording from iMessage, SMS, WhatsApp, Messenger, Telegram, Signal, Instagram DMs, and other visible chat interfaces • On Mac, select supported WhatsApp conversations from an unencrypted Finder or iTunes iPhone backup REVIEW BEFORE YOU EXPORT • Search messages, people, dates, sources, and attachments • Check extracted text against the retained source • Organize conversations into folders • Keep source files separate from derived text CHOOSE THE FORMAT YOU NEED • Searchable PDF for reading, printing, and sharing • CSV for filtering and analysis • HTML for a portable browser archive • TXT for a simple transcript • Long PNG for a continuous visual copy • RSMF 2.0 for compatible eDiscovery workflows SOURCE-LINKED RECORDS TextTrace retains the source you selected and creates SHA-256 integrity metadata. A matching checksum can help show that an exported file has not changed since it was created; it does not prove authenticity or legal admissibility. PRIVACY AND CONTROL WhatsApp TXT and ZIP files are parsed directly. Visual imports show an on-device preview first. Cloud verification starts only after your consent. On Mac, supported local backups are opened read-only; TextTrace does not bypass backup encryption. IMPORTANT TextTrace does not recover deleted messages or certify evidence. Visual text recognition can contain errors, so compare important content with the retained source. Some features require a TextTrace Pro subscription.
