About

Pico PDF Viewer

Read full description

Pico PDF Viewer is a very lightweight, local document viewer built around fast switching: authorize one folder, and jump between the PDFs and Markdown files inside it without picking a new file every time. ■ PDF reading ・Continuous scroll or single-page mode, pinch to zoom and pan for detail ・Full-text search (on supported devices) — jump straight to a hit, highlighted ・Bottom thumbnail strip to jump around long documents quickly ・Immersive controls — tap anywhere to show or hide them ■ Markdown viewing and editing ・Fully styled preview: headings, lists, quotes, code blocks, tables ・Edit in place and save — "Save" overwrites the original file directly, no switching to another app ・Formatting toolbar (headings, bold, italic, lists, code, tables, links) and a line-number gutter ■ Quick switching A side drawer lists every PDF/MD in the current folder — tap one to switch, no need to go back to the list first. ■ Three themes, three languages Dark, light, and warm themes switch instantly, or follow your system's dark mode setting; the interface is available in 繁體中文, English, and 日本語 at any time. ■ Fully offline Every file is read, rendered, and edited entirely on your device. There is no server and no account, and nothing is ever uploaded. The only network activity is the bottom Google AdMob banner (no interstitial ads) — see the privacy policy for details. You can also open a single file directly from another app's "Open with" or share menu (email, a download notification, …) without authorizing a whole folder.
