Kompresor

The archive manager that eats the archive as it goes.

Open anything, look inside first, extract on purpose. Kompresor handles the formats other tools give up on.

Shrink-extract

No room for both? You don't need it.

Normally extracting needs space for the archive and everything inside it at once. With shrink-extract, Kompresor removes the archive's data as each file comes out, so the archive shrinks while your folder grows. Works with ZIP, 7z, TAR and more.

Kompresor's Extract panel with destination, folder and existing file options and a Shrink-extract checkbox that removes the archive as files come out — Turn on shrink-extract right in the Extract panel.

An extraction in progress in Kompresor, asking what to do about a file that already exists, with Pause, Background and Cancel buttons — Pause, send to background or cancel any job while it runs.

Viewer first

Opening an archive never extracts it.

An archive opens like a folder. Browse, filter and preview first; extraction is always a step you choose. Disk images show their partitions as nested folders.

A ZIP file opened in Kompresor, showing a single logogen folder inside it — Open a ZIP and step straight into its folders.

The contents of a ZIP in Kompresor as a table of names, sizes, packed sizes, compression ratios, types and dates — Size, packed size, ratio and type for every file.

Kompresor's preview of an image inside a ZIP, with Image, Text, Hex and Metadata tabs and zoom controls — Inspect images, text, hex and metadata without extracting.

Kompresor's Find files window with file name, text and archive type fields and options such as search in archives — Find files by name or contents, even inside archives.

Kompresor browsing the root of a disk like a file manager, with a list of folders — Browse your drives with the same viewer.

Every format you've met, and the ones you haven't.

Yours to tune

Guided when you want it, configurable when you don't.

A setup wizard walks through the common jobs, and settings cover extraction, performance, compression and file types. Dark, light or follow the system.
