Changelog

Recent improvements

August 13, 2026

  • Every tool page now lists the standard, specification, or dataset its results come from, with the date those links were last checked.
  • Added an automated test suite covering conversion factors, encoders, round trips, and the bugs fixed this week, so a tool cannot silently drift from the standard it cites.
  • The site now sends a Content Security Policy that limits outbound connections to the two services documented in the privacy policy, making the local-processing promise something your browser enforces rather than a claim.
  • Published a security contact at /.well-known/security.txt.
  • Fixed a broken half-character in the Unicode Text Generator style previews.
  • Added automatic sitemap freshness dates and a release-blocking SEO audit for titles, descriptions, canonicals, headings, social cards, structured data, and sitemap coverage.

August 12, 2026

  • Added a Coverage Calculator that turns a room measurement into the number of boxes, rolls, bags, or tins to order, with a waste allowance and support for area, volume, and length products.
  • Store owners can configure the calculator for one product and embed it on a product page with a small script. Shopper measurements stay inside the frame and are never sent to MiniUtil.
  • Fixed character counting in the Word Counter so an emoji counts as one character rather than two.

August 11, 2026

  • Added six technical field guides: Content-Disposition filename encoding, Subresource Integrity failures, sharing a HAR file safely, Unix timestamp units and the 2038 limit, ISO week numbering, and OAuth PKCE.
  • Added a custom toolkit builder: pick up to 12 tools, reorder them, and use them together on one page. The selection is saved in your own browser and never sent to MiniUtil.
  • Fixed a comparison table in the field guides that could omit a cell when two cells in a row shared the same text.

August 10, 2026

  • Added a visible privacy indicator to every tool page stating whether input is processed locally or sent to an external service.
  • Added the Photos & Graphics to PDF toolkit and a matching guide connecting HEIC, SVG, PNG, JPG, and PDF image tools into one workflow.

August 9, 2026

  • Redesigned the Website Design Simulator with a collapsible desktop control sidebar and a wide, independently scrolling live preview.
  • Added six search-focused guides for ICS files, CSV-to-JSON conversion, JWT decoding, web image formats, business days, and Content Security Policy.
  • Connected relevant tool pages back to their practical guides for easier multi-step workflows.
  • Removed the public repository link from the contact page and moved tool reports and suggestions to email.

August 8, 2026

  • Moved mobile navigation into the sticky header with site links, tool search, and the complete category catalog.
  • Added visible MiniUtil attribution links inside every embeddable widget and in copied iframe snippets.
  • Added a private Search Console opportunity analyzer for positions 4–20, CTR gaps, and country-level localization review.
  • Added four connected toolkits, four original field guides, share actions on every tool, and three embeddable widgets.
  • Launched a fully translated Spanish word-counter pilot with reciprocal language annotations.
  • Audited the nine withdrawn converter routes: five remain noindexed and four now provide honest, reviewed conversion guidance.
  • Added CORS, Content-Disposition, cookie, JWK thumbprint, ICS validation, CSV column extraction, TOML, and Data URI tools.
  • Added PKCE, RRULE, HAR sanitizing, security.txt, CSV deduplication, CSP, ULID, and Permissions Policy tools.
  • Rebuilt the Website Design Simulator with a full-width device canvas and expanded theme, layout, typography, section, content, and CSS export controls.
  • Added eight focused tools for JSONL, UUID v7, JSON Pointer and Patch, CSV repair, HTTP caching, ICS files, SRI hashes, and cron schedules.
  • Fixed the Energy Converter input crash and made its conversion factors internally consistent.
  • Improved CSV parsing, word analysis, content accuracy, related-tool links, and interaction measurement.
  • Added public information about MiniUtil's purpose, testing approach, corrections, and privacy.
  • Improved sitemap freshness signals and prepared IndexNow submission support.

August 7, 2026

  • Updated the homepage tool finder so category controls fit properly on desktop.
  • Refined homepage navigation and category discovery.

August 6, 2026

  • Added practical conversion guides for formats that cannot be reliably converted with a simple browser-only interface.
  • Expanded canonical metadata, structured data, category pages, and sitemap coverage.
