What Pikkit is
Pikkit is a hand-built collection of 495 small tools, each doing one job well: pick an emoji, convert a file, check a sum, sign a PDF, tidy a recording. Every one runs entirely inside your browser โ the page IS the program โ so there is nothing to install, no account to create, and nothing you enter is ever uploaded. Load a tool, go offline, and it keeps working.
Each tool page explains what the tool does, how it works and, just as deliberately, what it can't do: the PDF compressor says its method turns text into images, the audio speed changer says pitch moves with speed, the sharpener says it can't recover detail a photo never captured. Tools that compute something are checked against independently worked-out values before they go live. The guides go deeper into the ideas behind the tools โ why Easter moves, how QR codes survive damage, what a one-rep max measures โ and the about page covers who makes all this and how it's funded.
