Social Media Tools

Balanced broad, mid and niche hashtag sets with banned-tag warnings.

Grab YouTube thumbnails in every available resolution, plus the embed code.

Twenty-six platform limits at once, counted the way each platform counts — weighted, emoji-aware and with the fold marked.

Titles built from the patterns that actually get clicked, each scored on length, keyword position and how much it over-promises.

Expand a topic into a tag set that fits the real 500-character budget YouTube allows, ordered by how much each tag earns its place.

Captions with a hook that survives the 125-character cut, a call to action, and a hashtag block kept inside the limit.

One picture into every size a platform asks for, cropped around the part that matters, downloaded as a zip.

Reframe a clip for Reels, Stories, Shorts or a square feed — cropped around the point you pick, or filled with a blurred copy of the footage.

Pull a full-resolution still out of a video for a cover or a thumbnail, with a contact sheet of candidates to choose from.

Everything for getting a picture into the shape, size and format something else will accept — compression, resizing, cropping, conversion between formats and background removal.

Everything for the PDF itself — joining files and taking pages out, making one smaller, stamping, redacting and locking it, and converting it to and from Word, Excel and images.

Tools for text and the formats it gets trapped inside — counting and analysing writing, converting between data formats, and pulling readable text back out of pictures.

The technical side of getting a page indexed and shared properly: the tags that decide how it appears in results, the structured data behind rich results, and the files crawlers read before anything else.

The small utilities that come up mid-debug — reading a token, testing a pattern, generating identifiers, tidying a query — without pasting anything sensitive into a stranger's server.

Tools that make something from nothing much: a QR code, a password, a favicon set, a colour scheme, a font pairing, or speech from a block of text.

Everyday arithmetic that is easy to get slightly wrong: percentage change and reverse percentages, an exact age, a loan repayment, a unit conversion, a meeting time across three countries.

Video and audio handled in the browser itself, with ffmpeg compiled to WebAssembly — so a large file is never uploaded, and there is no queue behind other people's jobs.
