File Tools

Manage and inspect files online with NevioTools. Create and extract ZIP archives, split and join large files, calculate checksums, compare file contents, detect file types, rename files in batches, merge text files, and find duplicates using one organized collection of tools.

ZIP & Unzip Files

Create ZIP, TAR, TAR.GZ, TGZ or GZ archives, or safely extract ZIP, RAR, 7Z, TAR and GZ formats locally.

Split & Join Files

Divide large files into smaller parts and reassemble those parts into the original complete file.

File Hash & Checksum Calculator

Calculate MD5, SHA-1, SHA-256, SHA-384 and SHA-512 checksums to verify file integrity.

Compare Files

Compare any two files byte by byte, calculate SHA-256 hashes and inspect line-by-line text differences when available.

File Type Detector

Identify a file's actual format from signatures, container structure and safe text inspection, then check its extension.

Batch File Renamer

Rename multiple files using prefixes, suffixes, numbering patterns or find-and-replace rules.

Merge Text Files

Combine validated UTF-8 text files in your chosen order with controlled separators and optional filename headers.

Find Duplicate Files

Find exact duplicate files with size grouping, SHA-256 checksums and byte-for-byte verification.
