How to Use Deflate Raw Decompress

What is Deflate Raw Decompress?

Deflate Raw Decompress restores data compressed with raw Deflate (RFC 1951) — without a zlib header or Adler-32 checksum — back to its original readable form. This variant is distinct from standard Deflate decompression and is required when working with formats like PNG IDAT chunks, PDF FlateDecode streams, and custom binary protocols that use headerless Deflate. Attempting to decompress raw Deflate with a standard zlib decompressor will fail, making this dedicated tool necessary for debugging those specific formats.

Features

How do I use Deflate Raw Decompress?

Paste the Base64-encoded raw Deflate data — extracted from a PDF content stream, PNG chunk, or custom protocol frame — into the input field and click Decompress. The tool applies RFC 1951 decompression without expecting zlib framing bytes and displays the restored original content. If you receive a header or checksum error, your data likely uses standard zlib-wrapped Deflate; in that case switch to the Deflate Decompress tool instead.
