A single self-contained HTML file that bundles the small utilities an IT admin, freelancer or content creator reaches for every week — audio/video conversion, image and PDF work, a subnet calculator, DNS/SSL checks, JSON & diff, hashing, encoders, barcode and QR generation, social captions and more. Open it by double-click, pick a tool from the sidebar, get to work. No install, no internet — and nothing you load ever leaves your computer. CA$7.50/mo (cancel any time) or CA$150 once, no account needed.
This is the actual page — not a screenshot. The frame below loads the Utilities Toolkit straight from the server. The full 65-tool file opens after purchase; the free PDF→PNG tool below is one of its tabs.
Desktop — 1280 px
Mobile — 390 px
Network, Media, Developer and Social — switch workspace tabs in the sidebar and the tool list filters to match. Actual screenshots from the running toolkit.
One HTML file, about 45 MB, with 65 tools registered as sidebar tabs. Every library it needs is embedded — PDF rendering, image decoding, an FFmpeg build for audio/video conversion, an offline AI model for background removal, hashing, diffing, QR and barcode generation. It runs entirely in the browser: your files are processed on your own machine and never uploaded. A handful of Network Diagnostics tools (DNS lookup, SSL certificate check, MX lookup, blacklist/RBL checker, SPF/DKIM/DMARC checker, IP/geolocation) call a public resolver at the moment you use them and are clearly labelled; every other tool works with the network off.
Drop a PDFRuns in-browserNothing uploaded
The free PDF→PNG converter is tab 1 of the Utilities Toolkit, kept free for everyone. Drop in a PDF and it renders each page to a PNG entirely in this browser — nothing is sent anywhere. The full kit adds 64 more tools in the same file.
No installer, no account, no browser extension. It is one file you own.
Double-click Utilities-Toolkit.html. It opens in your browser like any page — no setup screen, no login.
The sidebar lists all 65 across four workspaces — Network, Media, Developer, Social — each grouped further into categories like Audio & Video, Images & Photos, Network Diagnostics and Captions & Hashtags.
Drop a file or paste text. Everything is processed on your machine — with the Wi-Fi off if you like.
Put the file on a USB stick and it runs on a locked-down work laptop or an air-gapped box. One-time purchase, every computer you own.

The everyday jobs get done on a dozen different websites — each one uploads your file, caps the size, and hides half the features behind a subscription. Here is where one local file lands next to them.
