## What is OneMarkup?

Open and inspect the files people actually send you—from Files, Mail, WeChat, and any app that shares documents. Ordinary file preview, search, and editing stay on your device, with no account, ads, analytics, tracking, or in-app purchases.

PREVIEW MORE FILES
• PDF, common and modern image formats including WebP and AVIF, Office/iWork, audio/video, and USDZ with iOS system controls
• Complete ZIP website exports with index.html plus local CSS, images, fonts, and media
• CBZ comics, ZIP-compatible package contents, GLB structure, fonts, certificates, property lists, email, source files, and unknown binaries

READ AND EDIT
Read Obsidian-style Markdown with a table of contents, heading jumps, tasks, callouts, footnotes, frontmatter, tags, and wide tables. Edit text-based formats through a Files-visible working copy while the original stays untouched.

TRUSTED HTML MINI APPS
HTML and ZIP websites open as isolated trusted-network mini apps by default: JavaScript and package assets can run, while network access is limited to HTTPS/WSS. Switch to Offline Mini App or Safe Preview at any time. HTTP/FTP, embedded frames, unexpected in-view navigation, and arbitrary access to other local files remain blocked. Webpage code can still contact third-party servers or send information you enter when its own logic requests it.

QUICK ACCESS
Recent files automatically appear in widget choices. Add multiple OneMarkup widgets, then choose a different file, name, and icon for each—including HTML mini apps. Small files are kept as local copies by default so source permissions cannot strand a shortcut.


## Version history (last 4 releases)

### 1.6 — 2026-08-11

• HTML and ZIP websites now fill the screen, hide the status bar by default, and use plain Back and More icons with no button rings.
• Every recent file is available to widgets; each widget can choose its own file, name, and icon.
• Cold widget launches go straight to the file without flashing the app home screen.
• Files up to 100 MB are copied into Imports by default so Recents keep working; this can be disabled in Settings.
• Redesigned the World Clock, Focus Timer, and Memory Match mobile HTML mini apps.

### 1.5 — 2026-08-07

NEW
• Run trusted HTML and ZIP packages as interactive mini apps.
• Local JavaScript starts with network access blocked; HTTPS and secure WebSockets require a separate confirmation.
• Cookies, cache, localStorage, and IndexedDB are isolated per file and can be cleared at any time.
• Try three new self-contained mini apps: Aurora Clock, Focus Timer, and Memory Match.

SAFE BY DEFAULT
• Imported HTML and ZIP packages still open in Safe Preview with active code and remote resources blocked.
• Remote page navigation opens outside OneMarkup.

The example library now includes 29 items covering every preview category and the new HTML runtime.

### 1.3 — 2026-07-28

Edit the files you open and let OneMarkup save your changes automatically to a clear working copy in Files. The original stays untouched, so you can explore and revise with confidence.

New
• Edit Markdown, HTML, SVG, JSON, YAML, XML, subtitles, and other text-based files.
• Preview JSON and XML as structured views, YAML with line numbers, and SRT subtitles as timed cue cards.
• Add “Quick Preview Here” to the share sheet to inspect a file without leaving the current app.

Improved
• Share, open, and Recents flows now keep originals and edited copies clearly separated.
• More reliable handling for files from WeChat and other providers.

Fixed
• Quick Preview now handles back-to-back requests and more provider representations reliably.

### 1.0 — 2026-07-28
