Crinkler

Crinkler is a Windows linker and compressor for creators building tiny 32-bit demoscene productions. It is most compelling for 1k, 4k and 8k intros, where compact output matters more than broad compatibility. Its focused workflow is a poor match for larger executables or machines without SSE4.2.

Overview

Crinkler combines linking and compression, producing an executable that decompresses into memory when run. That puts size reduction directly into the build process rather than leaving it as a separate packaging step. The trade-off is specialization: this is a tool for small demoscene binaries, not a general-purpose solution for every Windows application.

The project’s latest release is Crinkler 3.0b. It is distributed under the zlib license, which allows commercial use subject to its conditions. A separate compressor library is available for tools that need to estimate compressed data size.

Key features

Compression built into linking

Crinkler uses context modelling and, by default, compresses code, optional text data and general data as separate parts. That approach fits productions where each byte counts, but the 64k uncompressed-size ceiling applies to each part. Projects that exceed it are outside the tool’s intended range.

Visual Studio workflow

Crinkler can replace the Visual Studio linker, supports its basic options and is configured through project settings. For developers already building in Visual Studio, that provides a direct way to incorporate it into the project; users of other toolchains may need to build their own integration. The project welcomes integrations and recommends using its master branch as a basis.

Build and size constraints

Building Crinkler requires Visual Studio 2022 or later. Custom assembly build rules also require nasm.exe on the executable path. Tiny-header mode can make decompression prohibitively slow for files significantly larger than 1 KB, so its size-saving approach is not a sensible default for larger inputs.

Pricing

Crinkler is free: the Crinkler plan costs nothing and covers the compressing linker for small 32-bit Windows executables. There is no paid tier or trial to weigh against it. The perpetual license model and zlib terms allow commercial use subject to the license conditions.

Platforms

Crinkler runs on Windows 10 or later, supports 32-bit executables in EXE format and requires SSE4.2. It can target older Windows versions, but both Crinkler 3.0 and the executables it produces still require SSE4.2. That hardware requirement is a material compatibility constraint for older CPUs.

Who it's for

Crinkler is for demoscene creators compressing small Windows productions, particularly 1k, 4k and 8k intros. It also suits developers who want to integrate its compressor library into another tool for size estimates. It is not the right choice for projects with parts above 64k uncompressed, or for teams that need a cross-platform linker.

The README points users to GitHub Releases for downloads and to the manual for usage guidance and version history. General questions and discussion go to the Pouët.net forum.

Pros and cons

• Purpose-built for tiny productions: linking and compression in one step suit strict demoscene size budgets.
• Visual Studio support: project-settings configuration makes it a natural fit for developers already using that environment.
• Commercial use permitted: the zlib license allows it subject to its conditions.
• Strict hardware and data limits: SSE4.2 is required, and each part is capped at 64k uncompressed.
• Narrow workflow: broader toolchain use depends on integration work, while tiny-header mode can slow decompression substantially beyond 1 KB.

Alternatives

For a wider comparison, browse Executable Packers.

Choose Obsidian if you want a freemium option spanning Windows, mobile, desktop and browser-extension platforms, with a free plan described as unlimited and requiring no sign-up. StarForce Reader is another free option for readers seeking a cross-platform alternative. Consider UPX for a free packer available on Linux, macOS and Windows, or MPRESS if its free offering and support for PE32, PE32+, .NET and Mac-Darwin executable formats better match the target.

Windows PE Packer is a free Windows alternative; papaw is free software for Linux and self-hosted use. AlushPacker is another free Windows option, while Enigma Virtual Box is free Windows application virtualization software.

Verdict

Choose Crinkler if you are making a tiny 32-bit Windows demoscene executable and want linking and compression in one focused workflow, especially within Visual Studio. Its free commercial-use license and separate compressor library add flexibility, but the SSE4.2 requirement and 64k-per-part cap are decisive constraints. For broader platform coverage, larger inputs or a different packaging approach, look elsewhere.
