Fidelity When Converting CAB to SEA

Be cautious running SEA files from untrusted sources For the best results, start with the highest quality Cabinet Archive source file available. Self-Extracting Archive is known for no decompression software needed — just run the file. This means your converted output will benefit from Self-Extracting Archive's core strengths. Meanwhile, the original Cabinet Archive's advantage of native Windows installer format with built-in extraction may not fully carry over, depending on Self-Extracting Archive's capabilities. Artifacts — unwanted visual or auditory imperfections — are minimized through Xonvert's tuned encoding parameters. For Self-Extracting Archive, the default quality settings sit well above the threshold where artifacts become noticeable.

Re-packaging files from Cabinet Archive to Self-Extracting Archive archive format changes the compression algorithm and container structure while preserving all archived contents. File permissions, directory structures, and timestamps are maintained when supported by both formats. This conversion is useful when a recipient's system requires a specific archive format.

Compression trade-off: Your lossless CAB source retains all original data. Converting to lossy SEA will reduce file size substantially, but some data is permanently discarded. Use the quality slider to balance file size against fidelity.
