Reverse File

Reverse files byte-by-byte, line-by-line, or word-by-word with chunked streaming for large files.

Random Binary File Generator

Generate cryptographically random binary files with entropy visualization and byte distribution histogram.

GZIP Compress & Decompress

Compress and decompress GZIP files using the native Compression Streams API with original filename extraction.

LZMA Compress & Decompress

Compress and decompress LZMA files with adjustable levels 1-9 using the Lempel-Ziv-Markov chain algorithm.

Split & Merge Files

Split large files into smaller parts by byte size or line count, then merge parts back with HJSplit-compatible naming.

ZIP Split & Reassemble

Split large ZIP archives into smaller byte-level parts for email, FAT32, or cloud upload limits, then reassemble them back.

TAR Archive & Extract

Create and extract TAR archives with file explorer view, individual downloads, and .tar.gz/.tgz support via native decompression.

File Type Detector

Identify any file's true format via magic byte analysis with confidence scoring, MIME type lookup, and hex signature display.

ZIP Compress & Extract

Create ZIP archives from multiple files or extract contents with Deflate compression levels 0-9 and individual file downloads.

Bzip2 Compress & Decompress

Compress and decompress files using the Bzip2 block-sorting algorithm. Higher compression ratios than GZIP for text-heavy data.
