The Best Free Compression / ZIP program: a comparison. A Zip/compression program is an essential fixture on any computer. There are so many excellent free compression apps that I am always astounded when someone asks me if there is a good . But the real question is: which is the BEST free compression/archiving program available.
We set out to test what we thought to be the best free compression programs in a head- to- head QUANTITATIVE comparison, where we collected actual compression and extraction data on different system. We also took other, qualitative aspects into consideration, such as the features, the appeal of the interface, etc. Our preference for these is in that order, respectively. Table of contents: The list of programs that were selected.
The verdict: giving an opinion upfront. Assumptions and Priorities: why we made the decisions we did, and what we cared about most. Context and variables: more complicated than we thought. System Specs: the environments we used to test. The tests: extraction and compression.

The list of programs that were selected. We tested the following versions of these programs on 3. Win. RAR7- Zip. Haozip. Peazip. IZArc. Arcthemall. TUGZip. Iceows. Hamsterv.
Note that Win. RAR is NOT FREE; however we included it in our tests for benchmarking purposes, since it is considered by many to be the archiving program of choice. Why did we choose these and not others? See assumptions and priorities below.

The answer to the question . However, if I must give a recommendation I will say that my personal choice would be Hao. Zip, 7. Zip, (tied for first place), and then Peazip. Assumptions and Priorities: why we made the decisions we did, and what we cared about most. Assumptions: Here. We preferred programs that had had recent releases and/or were still in development, but anyway ended up including programs that were not updated in a long time.
We excluded Jzip, a program that we liked when it first came out, because it sneakily installed toolbars and crapware by default and buried the option not to do so in the . This is because ALL programs (save Win.
RAR) supported these two formats, so we could compare them. We included RAR for Win. RAR in the tests for benchmarking purposes.
We are aware that the selection of ZIP and 7. Z may have played a role in determining the eventual . Zip), but we estimate that these two formats (and RAR) are the most popular on the internet anyway.
Why we chose a multi part RAR for the extraction test: we extracted an extremely large multi part RAR archive. For example, I would consider a 1. I understand that this is a CHOICE, to say the former is better than the latter; others might have different prerogatives, and may evaluate the data differently. Priorities: here. Those who have different priorities can nonetheless read this article according to their different point of view; I hope that all the data and analysis are clear and easy to work with. Compression ZIP: Best overall compression performance for ZIP format.
The reason: all of them extract a huge range of formats; however, if you want to COMPRESS using a specific format that is not ZIP or 7. Z, then you will have to shop carefully to find an archive program that delivers what you want.
Whether it. Context and variables: more complicated than we thought. At first we wanted to test each software. However, we soon discovered that matters were much more complicated: each program had several compression . Moreover there were large differences in performance between 6. Below is the list or relevant variables.
Extraction vs. Compression. Format used: we only looked at ZIP, 7z, and RAR for Win. RARProfile used (typically called . Some programs performed admirably in a high specs configuration but miserably in less powerful machines.
The sizes and compression times were all over the map for different profiles and compression formats. Coming up with an answer to the question . But I do have an answer to the question, albeit with caveats. What the *bleep* is a profile? Every program has multiple compression profiles depending on the compression level and format. The essential tradeoff here is time: you determine just how much the program should try to compress, and it will implicitly take longer in processing. Typically, each program will offer 3 to 6 .
The screenshots below illustrate two examples of what we mean by profiles (for Hao. Zip, Hamster). 5.
System Specs: the environments we used to test. We tested on 3 configurations. For 3. 2 bit we ran virtual instances of Win 7 3. VMware, since we did not have access to a physical machine running Win 7 3. All ran on the same (7. Low spec. 32 bit- 2 High sepc.
