Changelog

Last updated: August 2026

What has shipped, month by month. Every entry here corresponds to real, deployed work — if a month is quiet, it says so by being absent rather than by being padded.

August 2026

  • Substantially expanded the written guidance on every tool page: practical tips, real use cases, honest comparisons with alternatives, and the mistakes each tool exists to prevent.
  • Added shareable links on the regex tester, cron builder, subnet calculator and diff checker — copy a link that reopens the tool with your exact input, stored in the link itself rather than on any server.
  • Added “Send to” chaining: hand a tool's output straight to another tool, such as Base64 output into the hash generator, without copying and pasting.
  • Rebuilt the guides into full articles with tables, worked examples and step-by-step procedures, and added a tenth guide on querying large CSV files with SQL.
  • Widened guide and information pages to match the rest of the site, with a table of contents that follows you as you read.
  • Removed the footer visit counter, which reset on every deployment and understated the truth. A counter that miscounts is worse than none.
  • Fixed the header navigation overflowing on tablet-width screens.

July 2026

  • Added the Document Privacy Inspector: see what a PDF or Office file carries beyond its visible content — author names, tracked changes, cropped-away image regions — and save a clean copy, with a re-scan proving what was removed and an honest report of what a clean copy cannot remove.
  • Added opt-in face detection to the Image Redactor. The model runs entirely in your browser; the weights are served from our own origin and nothing is sent anywhere.
  • Image Compressor gained batch mode: up to twenty images against one target size, with per-file results and a download-all.
  • The Hash Generator can now hash files as well as text, for checking downloads against published checksums.
  • Published three in-depth guides: why in-browser tools are more private than uploads, choosing an image format, and character encoding explained.

June 2026

  • Launched with the core tool set across seven categories: developer utilities, text tools, image tools, generators, measurement and conversion, network tools, and the WebAssembly-powered CSV & SQL playground.
  • Every tool runs entirely client-side from day one — no accounts, no uploads, no processing servers.
  • Published the first six guides and the site's legal and transparency pages.
