LOL, the eternal mask of darkness? Really? I never noticed that comment. Software authors like to compress/protect their executables. The fact that malware authors also use the same tools as legit software developers does not makes those tools 'evil'.

The eternal mask of darkness.

jcollake reviewed v3.02.2 on May 20, 2010

If you will download Google Desktop, you will see its installer is compressed with PECompact. I think that sums up the following defense against the 'only used by malware' comment.

My customers are NOT malware authors, they are software development companies.. from big name corporations to sole proprietorships. I try my best to deter malware abuse by working with anti-virus/anti-malware companies to help scan inside PECompact compressed executables. So, 'by something to hide', you should include intellectual property or copy protection mechanisms... NOT just malicious code.

Also, CPU cycles are more abdundent than disk and network I/O in many cases. If you have a 20MB executable, its nice if only 5MB needs to be loaded from the disk or network.

Well, there are always negative people.. I just want to say that with PECompact I do my best to ensure it is not abused by malware authors. Such abuse causes everyone headaches. I screen my customers, removed the free build, etc..

Are your criticisms valid? Well, sure.. The world isn't so black and white though. What may make no sense, or have no use to YOU, does make sense, or have use to someone else (other than malware authors).

Back when people used floppy disks this might have been useful. Nowadays, it's completely pointless. You can usually ZIP or RAR an executable smaller when packaging it up if it ISN'T precompressed. Exe compression does nothing to help the end user - it uses more RAM initially to decompress, takes longer to scan for a virus (obviously exponentially increased if you compact a lot of executables), isn't practical if you're already using NTFS compression, aids the spread of viruses as previously mentioned (if your viruskiller doesn't support a particular UPX or PECompact version, or doesn't support decompression at all, you're SOL). The cons of performing this action on exes FAR outweigh the pros.

Pembo reviewed v2.76 Beta A on Feb 6, 2006

A very tasty .exe & .dll compressor. Been using it for years now, aswell as UPX (Ultimate Packer for Executables).
Oh, by the way sn0wflake, viruses can not hide within compressed modules because most major anti-virus softwares support scanning inside the PECompact's modules!
...Anyway, hot product.

sn0wflake reviewed v2.76 Beta A on Feb 6, 2006

Great way too spred virus. Just compress the EXE file and email it to somebody :) Tried this many years ago and it worked. Note that it was on a closed LAN for testing purposes only.
Just a FYI to antivirus companies.

negate101, NSPAck is also a great competitor. Good compatibility, and higher compression ratios.

negate101 reviewed v2.64 on Jul 21, 2005

I don't trust UPack to be compatible, nor does the author claim that it is. If it saves a few more bytes sometimes (see Upack page, PECompact beats it on some files), it is because it has less features and compatibility. Do you really trust Upack on your commercial programs? PECompact has been the best packer to use for some time. It keeps getting better too, which is a great plus. UPX doesn't pack many modern executables. It used to be good, but the authors are not updating it. PECompact's plug-in support is awesome too. And I read on Bitum page that this version supports .NET executables, though I haven't tried it yet.

exactly - for software developers it's a great app, if they want to stop their own from modification/cracking/etc. but for end users? compress nero from 15mb to 5mb? it's not like 10mb is of gold value these days, esp since you lose on mem usage/startup delay/compatibility afterwards..

Galway reviewed v2.61 RC1 on Jul 5, 2005

The point of it is not rocket science, If you have a very large program file you can compress it so that it does not take allot of storage space. You obviously cannot zip and and still run it because of all the dependant files, since zip was not designed for this. This program uses the same technology but packs the file indepandantly and not them all together.

I have used packers before mearly just to protect them from modification or reverse engineering, and until a generic unpacker comes out it will serve this purpose in a basic manner.

If you dont know what its used for or cant think of a reason to use it then obviously its little use to you, but for software developers its a good tool.

guti reviewed v2.61 RC1 on Jul 5, 2005

Probably the best compression ratio for packing executables, because of the 7-Zip engine.

QQ reviewed v2.61 RC1 on Jul 5, 2005

what's the point in compressing apps like nero or bat anyway??

jcollake reviewed v2.61 RC1 on Jul 4, 2005

I DO NOT recommend using PECompact on your home computer for compression of your installed programs. Unless you are a software publisher, DO NOT DOWNLOAD this program. PECompact is oriented towards software developers who wish to compress/protect their executable for distribution. Home users should use a product like Aspack since it is more simple to use because it is not geared towards a high level of configurability and compression. Home users don't need PECompact's extra options and better compression ratio. Whatever issue with overlays you are having isn't going to be addressed. I haven't heard of any other reports, nor reproduced it, but even if such as issue exists, I am not concerned at all with overlays. And btw, they aren't actually part of the EXE structure, they are merely data appended to it. Typically, they are referenced by static offset so are not referencible after compression anyway. Regardless, developers can test their executable before distribution. I will no longer be monitoring this thread.

Dirk van Hoofen reviewed v2.60 on Jul 1, 2005

I detect, that PEComapct has generally problems with files, that contains Overlays.
I test it now with 4 (overlay)files.
After the compression you can not start this files.
Then I make the same test under ASPack and DIVI-Compress. This two tools interprets the internal EXE structure correctly and pack files in the "Succesfully" way.
This procedure is reproducible!

negate101 reviewed v2.59 on Jun 24, 2005

I also use TheBat! It compressed fine on my computer with PECompact. PECompact is the best exe packer out there, hands down.

Dirk van Hoofen reviewed v2.57 on Jun 23, 2005

This version create problems again. One example:
I compress TheBAT! prof with it (Overlay was present). After the compression the file was ca. 3 mb. If you start it now, nothing happens.
I test it on a other pc - same effect. Then I use it with NERO (protection fauld, if the compressed prog. starts).
Similarly to it I packed the files with ASPACK.
Contrary to PECompact I had no problems to start this files.

DLX reviewed v2.54 Beta A on Apr 16, 2005

Tried it with extreme prejudice (I am a long-time UPX user). However, I was quite nicely suprised. Solid program, although it seems that unpacking of the executable to memory is somewhat slower and more memory consuming then UPX. Also, in homepage they are comparing with UPX v1.24 while 1.25 stable and 1.9x beta versions have been out for quite a while. Understandable, though, they couldn't claim to be "The tightest executable packer in existence!" if they'd use that for comparing.
I'll think about buying PECompact - but not before UPX v2 comes out (should be within a month or two) and I can compare them both.

negate101 reviewed v2.50 on Mar 23, 2005

PECompact is a wonderful tool. It is by leaps and bounds the best executable compressor out there. One look by anyone who knows what they are doing and they will come to the same conclusion. I agree with the author, everyone can download ASPack and compare it for themselves. Some users here are never satisfied. Ppl who want more error reporting should use the console mode application. Though the GUI could use a bit better error reporting, I must admit. That said, as a previous reviewer here said, "PECompact is in one word, brilliant!".

jcollake reviewed v2.50 on Mar 23, 2005

[author] TheBat, and likely the others dirkes mentions are signed. Therefore, PECompact does not compress them since a SECURITY directory that usually indicates a signed executable. Compression will remove the signature, or make it invalid. Removing the check causes pec2 to compress it just fine. I will release a new version with this option. I encourage everyone to download aspack and compare it with pecompact. For some users, aspack may be the better choice. Again, PECompact is written to please software developers who want to compress their creations, not end users wanting to compress files on their PC. For example, a software developer would compress, then sign their executable -- making this security data directory problem a non-issue for them.

Dirk van Hoofen reviewed v2.50 on Mar 23, 2005

I test PECompact in the direct comparison with ASPack again. Without discussion ASPack works also with "overlays" correctly. PECompact has definitely problems with a lot of EXE files. For example it not compress the software Tweak XP-The BAT!-CD Extractor (only a small selection of soft).
PECompact do not compress this files (It show a error symbol) - ASPack reduced around at least 30 %.

jcollake reviewed v2.45 beta f on Mar 17, 2005

[author] Hi. The XP feature you mention is called a compressed file system and is indeed how end users should compress their files. However, generally speaking, end users are NOT the target audience of PECompact. Although it will compress executable files more than would any compressed file system, PECompact's primary use is for software developers and network administrators who wish to reduce the size and/or protect the content of executables distributed from their companies or servers. For this reason, PECompact is designed for advanced users and not intended for casual use by consumers. There are exceptions, such as the Password and MessageBox CODECs that allow end users to add special functions to programs on their computer. I hope this helps ;). I thank you all for your feedback. As you can see, I have acted on much of it.

Actually, this new version of PECompact, when used properly, outcompresses petite badly and is a close match for UPX on most files. Also, PECompact is much more stable across platforms than UPX (see UPX WindowsNT DLL relocation issues) currently is. Furthermore, PECompact is improving at a rate far quicker than either of those utilities, not to say they aren't good compressors also. PECompact is hardly a child's toy. In fact, it will probably post a definite second in compression ratio on Jeff's ACT comparison in December when the 'copy-overlay' option is properly turned off (the netscape.exe he uses to test has a huge [100k+]overlay that PECompact copies by default, to be safe). Furthermore, I've went to some length to make PECompact as stable and configurable as possible, giving it abilities and options that other compressors don't currently have. Well, there's my opinion, but I am a bit biased :)

gh0st reviewed v1.10 Beta 7 on Dec 23, 1999

Oh yeah one more point, both UPX and Petite are nag-free. UPX is a complete freeware that is offering the best compression ratio, compability, and speed (even in max compression), while Petite is a close second in compression ratio (but can be very slow with max compression) and offers a bit more control.
