Why a fifth of every profile picture is thrown away before anyone sees it, how much of a photograph survives each aspect ratio, why cropping from an on-screen preview is not really cropping, and the ten ratios the tool locks to.

Why a phone camera cannot throw a background out of focus, why the matte is the whole job and the blur is one line of code, and what the two subject models are each good at — with every control in the tool and what it is for.

Why an animated GIF is so enormous, when it is still the right answer anyway, why resolution beats the quality slider, and how to pick an audio format — with ffmpeg running in your own tab.

Disallow blocks crawling, not indexing — and combined with noindex it stops both from working. That, plus how often Google rewrites what you wrote, and the 7 SEO tools for the layer underneath your copy.

Catastrophic backtracking, tokens that were decoded but never verified, UUIDs that wreck an index, and certificates now on a 200-day clock. The 6 developer tools, and the failures behind them.

Stacked discounts, reverse GST, the interest you actually pay on a 20-year loan, and the three weeks a year when New York is four hours behind London — the 5 calculators, and the mistakes they exist to stop.

Readability budgets, the CSV values Excel quietly rewrites, and text trapped inside a scanned PDF. The 14 text tools, grouped by the four jobs they actually do.

A tested below-200-KB workflow, batch compression steps and format tradeoffs. Resize, choose JPEG or WebP, check the downloaded byte size and keep transparency when your image needs it.
