Tukuk-OS🎨 Design Studio
ℹ️ What this tool does & how it works
A design tool should be a canvas, a layer stack and an export button — and this page has all three, plus the things that make them usable: six starter templates built from real layer maths, drag handles to resize and a knob to rotate, snap-to-grid with centre and rule-of-thirds guides, undo and redo (40 steps, or Ctrl+Z), a layer list you can pick, hide and reorder, autosave to your browser so a refresh does not eat the work, and export as PNG (transparent), JPG or WebP at up to 4×. Keyboard: arrows nudge, Shift+arrows ×10, Ctrl+D duplicates, Ctrl+Z/Y undo/redo, Alt+click cycles layers. Everything is composited by your own browser — there is no account, no watermark, no upload; close the tab and the document is gone for good.
Why a plain-canvas studio beats a template portal
Every hosted design platform runs the same quiet business: your work markets the platform, the watermark is the upsell, and the file leaves your machine before you have really made it. This studio inverts all three — the pixels are composited by your browser’s own canvas engine, the export is assembled locally, and closing the tab destroys the document like a whiteboard. What it deliberately lacks: the million-template warehouse, stock search, licensed font libraries and collaborative cursors — every one of them a feature of the account that owns your file. What it does ship instead is honest: six starter templates composed from real layer maths, drag handles and a rotate knob, snapping to a grid with centre and rule-of-thirds guides, a 40-step undo history, autosave to your own browser, and a design file you can save as JSON and reopen later. The size presets are real too: Instagram and YouTube take exactly these dimensions because their own specs demand them.
