Dos View: Hex & Text Viewer

Any file in hex, binary, text

Free · Designed for iPad. Not verified for macOS.

Open any file of any size and see its bytes: hex dump, binary or text in 20 code pages, from CP437 and CP866 to UTF-16 — in a real DOS text-mode look. Dos View shows what is really inside a file. Open anything — a document, a photo, an app bundle, a log, a disk image — and read it byte by byte, in the look of a classic DOS text-mode viewer. THREE VIEWS • HEX — offsets, bytes and their characters side by side • BIN — every byte as eight bits • TXT — the file as text, with line wrap and record formatting dosview guesses the right view and code page from the file's first bytes, and you can switch with one tap. 20 CODE PAGES CP437, CP850, CP852, CP866, CP1250, CP1251, CP1252, ISO-8859-1, -2, -5 and -15, KOI8-R, KOI8-U, MacRoman, MacCyrillic, UTF-8, UTF-16LE and UTF-16BE. Old DOS texts with box-drawing frames and Cyrillic finally look right. SEARCH AND NAVIGATION • Find text, or bytes with an x: pattern — x:89 ?? 4E 47, where ?? matches any byte • Go to any offset, in hex or decimal • Format: split the data into records by a separator and see its bytes marked • Highlight of matches, the byte under the cursor always shown below FILES OF ANY SIZE The viewer core is written in Rust and reads only what is on screen, so a file of many gigabytes opens at once and scrolls to its end without waiting. MADE FOR TOUCH Drag to scroll, pinch to zoom, drag the offset column to narrow it, drag the text column to set the bytes per line, tap a byte to put the cursor on it, hold for the code page list. Everything you set is remembered. With a hardware keyboard you get the classic keys: F7 Find, F8 next match, F5 Go to and more. OPEN FROM ANYWHERE Open from Files, or pick a photo or video from the gallery. Or send a file to dosview from any app with "Open in…" and the share sheet — even plain text or a link, to see its UTF-8 bytes. ACCESSIBLE High-contrast palette, support for VoiceOver, Bold Text, Reduce Motion and larger text. Available in 46 languages. PRIVATE No accounts, no ads, no tracking, no network. Your files never leave the device.
