ToolSink

What we changed

A short public log of curation on ToolSink — new guides, pages we merged, and parts of the site we stopped promoting. This is maintenance, not a marketing feed.

    Calculators now show the formula and a worked example

    EMI, SIP, fixed deposit, and BMI pages spell out the formula and one numeric walkthrough. Merge PDF explains how page order becomes the new file. Near-duplicate widgets (a second SQL beautifier, placeholder text, reverse text, and the code playground) are off the directory, category grids, and search. They stay reachable by the old URL. A new guide lists which jobs stay in the browser and which four PDF actions upload for a single request.

    Overlapping Base64 guide removed from the library

    The shorter Base64 overview repeated the practical guide. It is no longer listed or indexed. Old links now point at Base64 Encoding and Decoding: How It Works.

    Public site narrowed to the toolkit

    Games are still playable by direct link, but they are off the homepage, menu, search, and About page. The public count is the working tools, not pastime pages. Editorial standards were published the same week.

    How-to library

    Original guides on PDFs, image formats, JSON, SQL, URL encoding, OCR, passwords, and barcodes. Each one explains the mechanism and the failure cases, then links to the matching free tool.

How guides are written is on the editorial standards page. Longer articles are on the blog.
