Crinkler

Crinkler is a free linker and compressor for tiny 32-bit Windows executables, especially demoscene intros. Its combination of build integration and small-output focus makes it a specialist tool; Windows 10 or later and SSE4.2 are required to use version 3.0.

Overview

Crinkler joins linking and compression in one step, producing an executable that decompresses into memory when run. That workflow suits creators working to the tight size budgets of 1k, 4k and 8k productions better than developers seeking a general-purpose executable packer.

The current release is Crinkler 3.0b. It is open source under the zlib license, which permits commercial use subject to its conditions. Its compressor is also available as a separate library, which can help other tools estimate compressed data size.

Key features

Compression designed for small outputs

Crinkler uses context modelling and by default compresses code, optional text data and general data as separate parts. This gives makers a focused way to shrink a small production as part of its build. The trade-off is a 64k uncompressed limit for each part, which rules out inputs that exceed that boundary.

Visual Studio linker replacement

Crinkler can replace the Visual Studio linker, supports its basic options and is configured through project settings. That makes it a practical fit for Windows developers already using Visual Studio, though its integration does not change the tool’s narrow focus on 32-bit outputs.

Toolchain integration

The project welcomes integrations with other tools and toolchains and recommends using the master branch as their basis. That is useful for toolmakers who want to incorporate Crinkler’s compression workflow, while teams building Crinkler itself need Visual Studio 2022 or later; custom assembly build rules also require nasm.exe on the executable path.

Small-file caveat

Tiny-header mode can make decompression prohibitively slow for files significantly larger than 1 KB. It is therefore not a setting to assume is suitable across a project’s full size range.

Pricing

Crinkler is free: its Crinkler plan costs nothing and includes the compressing linker for small 32-bit Windows executables under the Zlib license. The perpetual license model and permission for commercial use make it available without a paid tier, though use remains subject to the license conditions. There is no free trial because the software is free.

Platforms

Crinkler runs on Windows, and version 3.0 requires Windows 10 or later. It produces EXE files for 32-bit architecture; both Crinkler 3.0 and the executables it creates require SSE4.2. Older Windows versions can be targeted, but the operating system and CPU requirements still constrain who can build and run it.

Who it's for

Crinkler is best suited to demoscene creators making small 32-bit Windows productions, particularly 1k, 4k and 8k intros. Visual Studio users get a route to combine linking and compression within project settings, while toolmakers may find the separate compressor library useful for estimating data size.

It is a poor fit for projects with any part exceeding 64k uncompressed, users without SSE4.2, or developers who need a packer for architectures beyond 32-bit. General questions and discussion go to the Pouët.net forum; usage guidance and version history are covered in the manual.

Pros and cons

Pros

• Combines linking and compression, avoiding a separate compression step for its intended small-executable workflow.
• Visual Studio linker replacement and project-settings configuration suit developers already building in that environment.
• Free, open-source distribution under a license that permits commercial use subject to its conditions.
• A separate compressor library can help toolmakers estimate compressed data size.

Cons

• Windows 10 or later and SSE4.2 limit compatibility for version 3.0 and its output executables.
• The 64k uncompressed ceiling per part excludes larger inputs.
• Tiny-header mode can make decompression prohibitively slow on files significantly larger than 1 KB.
• Its 32-bit Windows focus makes it unsuitable for other target architectures.

Alternatives

For a broader set of executable-packing options, browse Executable Packers.

• Obsidian is worth considering if cross-platform availability matters: it supports Android, iOS, Linux, macOS, Windows and extensions, and has a free plan without limits or sign-up.
• StarForce Reader is a free alternative available across Android, iOS, Linux, macOS and Windows.
• UPX is a free option for users seeking an executable packer on Linux, macOS or Windows.
• MPRESS is another free option, available for macOS and Windows, with PE32, PE32+, .NET and MAC-DARWIN formats.
• papaw may suit users looking for free software on Linux or a self-hosted setup.
• Windows PE Packer is a free Windows alternative that processes 32-bit .exe files.
• AlushPacker is a free Windows alternative.
• Enigma Virtual Box is a free Windows application-virtualization option.

Verdict

Choose Crinkler if you are building tiny 32-bit Windows demoscene executables and want linking and compression combined in your workflow. Its focused compression and Visual Studio support are strong fits for that job, but the Windows 10 and SSE4.2 requirements, 32-bit target and 64k-per-part limit make another tool the better choice for broader compatibility or larger inputs.
