Social Media Tools

Tools for making, checking and measuring what you post — all of them running in your browser. Nothing you upload, paste or type here is sent anywhere, there is no account, and none of it connects to a platform.

What this is not

There is no scraping here. Nothing reads comments, follower lists or anyone's analytics — you supply the file or the figures. Nothing posts on your behalf or asks you to log in to a platform, and nothing generates a fake screenshot, a fake message or an invented metric.

Where a tool depends on something a platform decides — an image size, a caption limit — the figure carries the date it was last checked, because those change without notice and a number quoted with confidence is worse than one quoted with a date.

Write it

Counting a caption properly, and finding what will break when you paste it.

Caption Analyzer & Paste SafetyCounts the way a reader counts and the way the platform counts — those differ — shows where the feed cuts off, and finds the invisible characters that break links and tags.Start hereWord & Character CounterFor longer writing rather than captions: words, characters, reading time.Elsewhere on the site

Pictures for posting

Getting an image the right shape and size before a platform does it for you.

Grid & Carousel SplitterOne picture cut into profile tiles or seamless swipe slides. The pieces tile the original exactly — no lost or repeated pixel column, and it checks its own work.ExactSize a Photo for a PlatformPresets for the main feeds, with the honest part said out loud: you cannot stop recompression, but you can avoid the second lossy step. Never upscales.Elsewhere on the siteCompress to an Exact SizeFor an upload limit that refuses anything over a stated number of megabytes.Elsewhere on the siteHEIC → JPGThe format iPhones save in, converted to the one everything else accepts.Elsewhere on the siteRemove a BackgroundCut the subject out for a cover, a thumbnail or a flat-colour backdrop.Elsewhere on the site

Before you post it

The things in a file that you did not mean to publish.

Photo Metadata Viewer & RemoverSee the GPS coordinates, camera, serial number and timestamp buried in a photograph, and strip them out before it goes anywhere.Elsewhere on the siteImage RedactorCover a face, an address or an account number — then have it checked, pixel by pixel against the exported file, that the covered areas really lost their contents.VerifiedSanitize Before SharingThe same idea across a batch of files, including documents.Elsewhere on the site

Measure it

Numbers that mean something, with the denominator stated.

Engagement Rate CalculatorAll three rates at once — of followers, of reach, of impressions — because the same post is 8%, 3% or 1.2% depending on which you divide by, and all three get quoted as “the” engagement rate.Start hereMeeting Clock-Change CheckerA weekly slot fixes a local time, not a moment. Find every date a standing meeting quietly moves by an hour because two countries change their clocks on different days.UTM Builder & Naming CheckerCampaign links that survive an existing query string and keep the fragment last — plus the drift check that catches facebook, Facebook and face-book becoming three rows.

Where the interesting problems were

A caption is not as long as your counter says. Ask how long a family emoji is and there are three defensible answers: one character to a reader, seven code points underneath, and eleven in the units JavaScript counts by default. Almost every counter reports the last one, so an emoji-heavy caption is described as hundreds of characters longer than it is.

Dividing an image into three is easy until the width is odd. A 1081-pixel picture cut into three gives 360.33 pixels a tile; round it and you lose a column of the photograph, round up and you repeat one. On a profile grid that shows as a seam. Working out where each boundary falls, rather than how wide each tile is, means the pieces cover the original exactly — and every cut is checked against that before anything is exported.

A draw can be biased without being wrong-looking. Taking a random number modulo the number of entries favours whoever is at the start of the list, every time, for as long as you keep using it. Discarding the values that fall in the uneven tail costs nothing and makes the draw genuinely uniform.
