Chat Export Viewer opens WhatsApp exported chats on your phone β€” privately, offline, and without uploading anything to the cloud. SAVE SPACE, SKIP THE CLOUD BILL Cloud backups fill up fast, and extra storage gets expensive. Import a WhatsApp export, then keep it as a compact ZIP or TXT on your device. Bundle every chat into one space-saving ZIP β€” already-compressed chats stay nested without wasteful re-packing, so you avoid duplicate bulk. Same history, much smaller footprint β€” no monthly cloud plan required. IMPORT YOUR EXPORT β€’ Open .zip or .txt files from a WhatsApp export β€’ Import a multi-chat ZIP (or the app’s all-chats backup) in one go β€’ Re-import updates existing chats when there are new messages β€” skips duplicates READ LIKE A CHAT β€’ Familiar bubbles, timestamps, and date separators β€’ Search, filters, and jump to a date β€’ Photos, videos, audio, and PDF previews β€’ Reply quotes and photo captions in the same bubble ORGANIZE & SHARE β€’ Media and documents gallery β€’ Multi-select to copy or share messages and attachments β€’ Export one chat as compressed ZIP or lightweight TXT; PDF export with Premium β€’ Export all chats as a single re-importable ZIP backup PRIVATE BY DESIGN β€’ No account required β€’ Your chats stay on your device β€’ Interface in 23 languages Premium unlocks PDF export and an ad-free experience.
