## What is Doxio?

Every document tool you actually use — in one clean, black-and-white app that never sends your files anywhere.

COMPRESS TO A TARGET SIZE
Pick "Under 2 MB / 1 MB / 500 KB" and Doxio hits it — keeping the highest quality that fits. A 12-megapixel photo shrinks in about a second, full resolution preserved whenever possible. Perfect for upload portals, email limits and chat apps.

SCAN TO CRISP PDF
Turn photos of paper into clean, standard A4 PDFs with a high-contrast document filter. Reorder, remove, rebuild — then share one tidy file.

PDF TOOLS
Merge several PDFs, rotate pages, trim what you don't need, export. Password-protected files are detected honestly instead of producing blank pages.

CONVERT
Images → one PDF, or PDF → sharp PNG images at 2× resolution.

SIGN & FILL
Draw your signature with a finger and stamp it into the last page — as crisp vector strokes, visible in every PDF viewer.

PRIVATE BY DESIGN
Everything runs on your phone's own chip. No account. No cloud. No tracking. The engine is structurally incapable of uploading your documents — there is simply no network code in it.

FAIR PRICING
Every tool is free, forever, with no watermark and no daily caps. One optional purchase — Doxio Pro Forever — removes the page-per-document limit. No subscription, ever.

Doxio. Documents, done on your phone.
