Hex Editor is the fastest large files optimized binary file editor for Windows platform developed by Utility System Software. Hex Editor is extremely useful for viewing, modifying and analyzing hexadecimal data in extra large files and disks. For example, if you try to search and replace text/hex/decimal/binary data pattern in 1GB - 1TB file (or disc), you'll simply find no competitors for our product. The most frequent scenario in any competitive hexeditor will be: I'm sitting and waiting but never get the result.

Hex Editor is the only binary files editor that processes lengthy operations in large files just in seconds. You'll never find such performance anywhere else. The easy to use interface offers features such as searching and replacing, exporting, checksums/digests, insertion of byte patterns, a file shredder, concatenation or splitting of files, statistics and much more.

Hex Editor software is a great software to Batch Search and Replace keywords in PDF, EXE, DLL, OCX, Library, DAT etc. binary files.
