All 154 tools

Sixteen tools spanning the mechanical and the compositional — counting, cleaning and reformatting text, alongside four citation styles built from the current editions and an extractive summariser that scores real sentences rather than inventing them.

Sixteen image and photo tools built on the browser’s own canvas and codec stack. The privacy case is strongest here: a photo off a phone frequently carries GPS coordinates accurate to a few metres, so uploading one to a web tool to strip that metadata would hand the metadata to the tool.

Sixteen PDF tools covering both whole-document work and page-level editing. Pages are objects in the file, so removing, reordering or reboxing them copies rather than re-renders — which is why these are lossless and printing a page range to a new PDF is not. Everything runs in this tab, which matters when the document is a contract, a statement or a medical record.

Eighteen tools for building and securing things: formatters, encoders and a regex tester alongside cryptographic utilities built on the Web Crypto API. Keys, tokens and payloads are generated and parsed on your own device, because a secret pasted into someone else’s server is no longer a secret.

Sixteen tools for making a web page and making it findable. Colour conversion with exact maths, CSS generators that output what you would have written by hand, and the meta, schema and robots work that decides how the page is read once it ships.

Sixteen calculators built on arithmetic rather than tax tables, so they do not go stale in April. Each states its assumptions on the page — a retirement figure produced from an unstated return is a guess wearing a suit.

Sixteen everyday utilities and format converters, bidirectional where the formats allow it. Where a conversion is genuinely lossy the tool names what is being dropped — JSON has no comments, CSV has no types, and YAML can express structures JSON cannot round-trip.

Eight tools for job applications and getting things done. Documents are assembled and exported in your browser, and the planners keep their data in local storage on your device — a to-do list that syncs to somebody else’s server is a different product with different risks.

Sixteen calculators for what you are paid and what you owe on it. Every rate, band and threshold is an input rather than a constant, and presets state the tax year they came from — a calculator with rates baked in becomes silently wrong every April.

Sixteen estimators for your body and your building. Both halves follow the same rule: show the error bar or the waste factor next to the number, because a figure quoted bare gets read as a verdict — or gets you the wrong amount of paint.
