British startup claims to have developed tech that can deliver 65% lossless file compression - but you'll have to pay big for it

• CompressionX promises better compression and greener storage, but locks core features behind a monthly fee
• Claims of smart algorithms and 65% compression remain unverified and need independent testing
• The software mimics top file managers but adds a price tag where others are free

A British startup says it has achieved a breakthrough in data compression with a new tool which it claims can deliver up to 65% lossless file reduction.

CompressionX is touted as an alternative to the best file compression tools on the market. It is also marketed as both environmentally conscious and business-friendly.

But while the promise is bold, the price of entry may deter casual users, and the effectiveness or distinctiveness of CompressionX will need to be demonstrated under closer scrutiny.
