EnglishWhat Is Super Compression (supercompression.org)?
Updated
Super Compression is a niche information site about maximum file compression—programs, tools, and guidance for making archives as small as possible. It is aimed at people who want to shrink existing archives (7z, RAR, ZIP) and save storage space on a computer or in cloud storage. The site presents itself as a source of "useful programs/tools and information for maximum compression," and its featured content is a tool called Ultra7z Archive Optimizer.
What the site covers
The site's content sits in the archiver/compression space. Its featured post (published October 17, 2024, in the "Archivers" category) profiles Ultra7z Archive Optimizer 1.15, a Windows-style repacking tool. The post describes it as follows:
| Feature | What the site says |
|---|---|
| Core function | Optimizes and converts 7z (and RAR, ZIP) archives into smaller 7z archives |
| Compression method | Auto-switches between PPMD, LZMA, LZMA2, DEFLATE, DELTA, and BZIP2 during archive creation |
| Tuning | Improved (tuned) LZMA for JPG, BMP, WAV, EXE and similar file types |
| Compatibility | Fully compatible with the original 7z format |
| Ratio claim | Higher compression than non-tuned original 7-Zip |
| Workflow | Batch processing via drag-and-drop; "Fast" and "Ultra" repacking modes |
| Pitch | Shrink old and new archives "in one click" to save space and avoid overpaying for storage |
These are the site's own claims; the page does not publish benchmark data, so treat the "better than 7-Zip" ratio statement as a vendor claim until you test it on your own files.
Who it is for
- Storage-constrained users — anyone paying for cloud storage or running low on disk who wants existing archives reduced without re-collecting the source files.
- 7z users with mixed content — people archiving folders that contain images, audio, and executables, where per-file-type tuning can matter more than a single global setting.
- Batch repackers — users with many old archives who want drag-and-drop conversion rather than one-by-one recompression.
It is less relevant if you only occasionally zip a few documents, or if you need cross-platform tooling—the page describes a Windows-oriented utility and does not mention Linux or macOS builds.
How to evaluate it before relying on it
- Pick a representative archive you already have (ideally one with JPGs, WAVs, or EXEs, since those are the tuned types).
- Record its current size, then repack it with the tool in Fast mode and again in Ultra mode.
- Compare sizes and verify integrity—open the repacked archive and confirm files extract correctly, since format compatibility claims should be checked on your own data.
- Check the time cost—Ultra mode will be slower; decide whether the space saved justifies it for your archive volume.
Common sticking points to watch for: repacking is not the same as recompressing from originals, so gains depend on how the source archive was made; and very small archives may show little or no improvement.
Practical context
The site functions as a blog-style hub: a featured tool write-up plus an "Archivers" category for related posts. If you arrived looking for a download portal, a comparison database, or documentation, the page evidence does not show those—it shows editorial posts about compression tools. The practical value is in the tool descriptions and the repacking workflow they suggest, not in a catalog of software.
If your goal is simply smaller archives, the site's core suggestion—repack old 7z/RAR/ZIP files with tuned settings and batch-process them—is a reasonable starting method regardless of which specific optimizer you use.
