About FileKnack

FileKnack is a collection of free online tools for people who need a working file utility without signing up for anything. Everything runs in your browser (compression, parsing, generation) so your files never leave your device.

Why we built this

Most "free online file tools" ask you to upload your file to their server, then try to upsell you a subscription before you can download the result. That is slow, invasive, and unnecessary. Modern browsers can do all of this work locally.

Our methodology

Each tool is built around a specific, measurable job: compress a PDF to exactly 100 KB, merge CSVs with mismatched columns, generate a VAT invoice as a real PDF. We don't ship a tool until we can test it against the actual targets users would hit.

For calculators and finance tools we cite official source material (IRS, HMRC, CRA, ATO) and show a "last reviewed" date on every page so you can judge how current the numbers are.
