11月1日 的 Hex Editor — Binary Viewer 應用程式分析

A fast, focused hex editor for Android. Open any binary file — PNG, ZIP, ELF, firmware, save games, network captures, archives — and read it the way developers do: byte by byte, hex and ASCII side by side. Hex Editor is built for engineers, reverse-engineers, security researchers, students, and anyone who needs to peek inside a file. It's read-only by default — your data is never modified unless you explicitly switch to edit mode. Everything happens on-device. There is no account, no telemetry, no cloud, no ads when you upgrade. WHAT YOU CAN DO • Open any file via SAF — no permission prompts beyond what Android already shows. • View hex + ASCII side by side. Smooth paged scrolling handles files up to gigabytes. • Search for hex patterns ("89 50 4E 47") or ASCII strings, jump between matches. • Goto offset — decimal, hex, or a math expression (0x1000 + 16). • Bookmark interesting offsets and jump back any time. • Data inspector: int8/16/32/64, uint, float32/64, LE/BE, bit grid, header bytes. • Hash any range — MD5, SHA-1, SHA-256, CRC32 — for quick verification. • Extract strings — ASCII, UTF-16 LE, UTF-16 BE — minimum length tunable. • Compare two files byte-by-byte with diff offsets, navigation, and shift detection. • Auto-detect file structure for PNG, ZIP, PE, and ELF — chunk and section regions. • Histogram and entropy for any selection — spot compressed or encrypted blobs at a glance. • Edit bytes, insert, delete, replace, apply binary patches. Full undo / redo history. • Export to xxd or Intel-HEX. Re-import patches and replay them on another file. PRIVACY-FIRST Hex Editor is fully offline. Your files never leave your device. No account, no cloud, no analytics. The Pro upgrade unlocks editing and removes the single small ad — your data stays yours either way. Read the privacy notice before you install: it's short and honest. DESIGNED FOR FOCUS • Material 3 dark theme tuned for long reading sessions. • Monospace grid with byte-level selection and range anchors. • Tab-switchable density and address base (hex / dec / oct). • Onboarding tour, contextual hints, and tooltips on every tool. UPGRADE WHEN YOU NEED IT The free tier is fully functional for reading, inspecting, and analyzing binaries. The optional Pro one-time purchase unlocks editing, patch tools, and removes the single ad. Buy it once, keep it forever — no subscription. Built by a small team in Bangkok, for developers everywhere.
