Archives
Create ZIP archives, inspect entries and extract files, or compress and decompress GZIP logs and data. Process supported archives without uploading them.

Create a ZIP
A few files. One easy-to-share package.
Extract ZIP
Extract every supported ZIP entry or select files by path.
ZIP File List
Search a ZIP’s contents and export its file list as CSV or text.
Extract GZIP
Restore one .gz or .gzip file and download the original bytes.
GZIP compressor
Compress one log, text or data file into .gz for transfer and archiving.
Extract EML attachments
Recover original MIME attachment bytes from up to 500 local EML files with a complete filename map.
Compare ZIP contents
Compare actual expanded files inside two ZIP archives while ignoring packaging timestamps, order and compression.
Binary byte differences
Locate exact differing offsets and both hexadecimal byte values in two local binary files.
Split disconnected STL components
Split binary or ASCII STL by exact shared-edge connectivity while retaining original coordinates, normals and triangle data.
Recover original Office media
Recover original DOCX, PPTX and XLSX media with document stories, slide shapes and worksheet drawing anchors.
Batch STL geometry measurements
Measure up to3,000 local STL models with complete bounds, dimensions, area and explicitly qualified closed-surface integrals.
Rename file copies with a complete plan
Add a basename prefix, suffix or counter to local copies, preserving the final extension and every original byte in a ZIP.
Choose the right tool
Use ZIP to package multiple files and GZIP for one data stream. Check entry names, expanded sizes and the restored result. Compression does not encrypt data, and an archive that downloads successfully is not verified until its expected contents can be recovered.
