Compression Playground
Compress and decompress text or files locally with browser-based compression tools.
Paste text or choose a local file, select a compression format, and create a downloadable result without uploading your data. The report shows input size, output size, compression ratio, and practical notes for round-tripping compressed payloads.
Choose a file when you want byte-for-byte file compression. Leave this blank to use the text box below. Keep files under 25 MB for responsive browser-local processing.
How it works
Compression rewrites repeated patterns into a smaller byte stream when the input has enough redundancy. This page lets you compare source size against compressed size, then export either the encoded text form or the raw compressed bytes from a local file workflow.
Use Base64 when you need to paste compressed bytes into a text-only place, or hex when you need an easy-to-inspect byte representation. Decompression expects the same format and compression choice that produced the data.
Small inputs, already-compressed assets, encrypted data, and random-looking bytes may become larger after compression. Browser support for these formats varies, so verify important payloads with the tool or system that will consume them.
