Online decompressor

Test sapblob directly in the browser. The page runs fully client-side via Go WebAssembly, so the uploaded file never leaves your machine. For a public GitHub project this is the right trade-off: low friction without a server-side privacy problem.

What this page does

It reads the SAP wrapper, removes the padding bits, decompresses the raw DEFLATE payload, and lets you download the recovered file. When the recovered payload type is recognized, the browser download uses a matching extension such as .pdf or .png. Unknown types fall back to .bin.

What it does not do

It does not guess business context or invent metadata with false confidence. It only assigns a file extension when the recovered payload can be recognized from well-known magic bytes. If detection is uncertain, the result stays neutral.

Install or download

Prefer the browser for quick tests. For local CLI use, open the Install page for release downloads, installer scripts, and build-from-source instructions.

What the download name means

When the recovered payload type is recognized from magic bytes, the browser uses a matching extension such as .pdf or .png. Otherwise the fallback extension is .bin.

Batch results

Each card is independent. Successful outputs can be downloaded one by one.
