HexDrop — Hex Viewer & Binary File Inspector

Description

Drop any file. View it as hex, ASCII, and decoded text. Free for everyone, with optional Pro tier for themes and bookmarks. HexDrop is a fast, in-browser hex viewer built for game modders, reverse engineers, security researchers, and anyone who needs to peek inside a binary file without spinning up a full hex editor. Drop any file on the tab. See hex and ASCII side by side. Click any byte to see its hex value, decimal value, and character. Search by hex, decimal, ASCII, or limit search to a selection. Jump to any offset. Switch encodings (UTF-8, UTF-16 LE/BE, Windows-1252, ASCII). Export as hex dump, hex only, decoded text, or PDF. Handles files up to 100MB. No data leaves your device. Zero network in the free version. Fully offline. ═══ HEXDROP PRO — $4.99 lifetime, built for power users ═══ Optional one-time upgrade unlocks the toolkit modders and reverse engineers actually use: • PATTERN WILDCARDS — search "4D 5A ?? ?? 50 45" style. AOB-scan binaries, find PE headers, locate game memory patterns. The "??" matches any byte. • HASH CALCULATOR — SHA-256, SHA-1, and CRC32 of the full file or any selection. One click to copy. Verify patches, check file integrity. • VALUE DECODER — select bytes, see them decoded as int8/16/32/64 (signed and unsigned), float32/64, in both little-endian and big-endian. Identifies HP, gold, position values, etc. instantly. • STRUCTURE TEMPLATES — define a struct (u32 width, char[8] magic, etc.) and apply at any offset to see every field decoded. Built-in presets for PNG, BMP, ZIP, WAV, PE/EXE headers. Map any binary format yourself. • DIFF MODE — load two files side-by-side, every differing byte highlighted in red. Jump to next/previous individual difference. Switch to "Changes Only" view for cheat-engine-style change list with int/float interpretations. Export the diff as a binary patch file. • ANNOTATED REGIONS — highlight any byte range with a color and label. Annotations save per-file (keyed by file hash, never file content) so they come back next time you open it. Map out file formats as you reverse-engineer them. • BOOKMARKS — save offsets in any file with notes. Returns when you reopen the same file. • 5 THEMES + CUSTOM THEME BUILDER — Matrix Green, Cyberpunk Pink, Ocean Blue, Sunset Orange, plus a custom theme builder where you pick your own background, accent, and text colors and HexDrop derives the full palette. One-time payment, lifetime access. No subscription, no auto-renewal, no telemetry. Powered by ExtensionPay (Stripe-backed). ═══ PRIVACY ═══ The free version makes zero network connections. The Pro version's only network call is to extensionpay.com to verify your Pro license — no file data is ever transmitted. All hash computation, diff comparison, pattern search, value decoding, structure parsing, and annotation storage runs locally in your browser tab.
