TeraPDF — Huge PDF Reader

TeraPDF opens PDF files of any size — instantly. Whether it's a 10-page invoice
or a 1 GB, 10,000-page technical manual, TeraPDF streams pages on demand, so the
document is on screen in a second and your phone's memory stays low. No waiting,
no "file too large", no crashes.

It's also a PDF → Word converter: export the text and tables from a PDF straight
to an editable .docx file, entirely on your device.

WHY TERAPDF

• Truly huge files. Built around on-demand page rendering, TeraPDF handles
multi-hundred-megabyte and multi-thousand-page PDFs that make other readers
freeze or run out of memory.
• Instant open. Files are read in place — there's no slow copy or import step.
• Light on memory. Only the pages you're looking at are rendered, so even a
giant document scrolls smoothly on modest phones.

READING

• Smooth vertical scrolling through thousands of pages.
• Pinch to zoom and pan, with a crisp re-render at the zoomed level.
• Page thumbnails grid — jump anywhere at a glance.
• Go to page — jump straight to any page number.
• Night mode — invert the page to dark for comfortable reading at night.
• Remembers your place — reopen a file and you're back on the last page you read.
• Recent files — pick up where you left off in one tap.
• Open PDFs directly from other apps with "Open with → TeraPDF".

SEARCH

• Full-text search across the whole document (for PDFs that contain a text
layer), with a result list that jumps you to the matching page.

EXPORT TO WORD (DOCX)

• Convert a PDF's text — and simple tables — to an editable .docx file.
• Runs entirely on your device; the result is saved wherever you choose.
• Great for reusing content from reports, statements and documents.
(Note: scanned/image-only PDFs have no text to extract, and very complex
layouts are reconstructed approximately.)

PRIVACY FIRST

• Your PDFs never leave your device. Files are read, displayed and converted
locally — nothing is uploaded.
• No analytics SDKs, no tracking, no account.
• A single optional banner ad (Google AdMob) keeps the app free — and you can
turn ads off completely in Settings.
• Files are only ever accessed when you pick them with the system file picker.

OTHER

• 16 interface languages, switchable inside the app.
• Light / dark / system theme.
• Small, focused app — no bloat.
