PLAYABLE PIXELS · LIVE SPACE HEAT · NO UPLOAD

Make a sticker sheet. Check the cutlines.

Drag, resize and rotate real pixels on the sheet. Watch space and overlap feedback live; run preflight only when you want exact PDF/SVG evidence.

Pointer tilt and the inspection lens are visual digital-sheet aids. Arrow keys move the selected sticker. F toggles focus view and Escape exits it. Physical cutter fit is not assessed.

METHOD

What is actually computed

  1. Exact container boundaries reject animation, trailing payload, SVG/HTML polyglots and oversized decode surfaces.
  2. Marching squares traces raster alpha; deterministic simplification and bounded offsets expose islands, holes and narrow features.
  3. MaxRects and row packers use fixed tie breaks. The PDF page box uses exact mm-to-point conversion; decoded pixels are re-encoded without source metadata.

BOUNDARY

A digital preflight, not a cutter promise

The PDF and SVG include no registration or sensor marks. They are not Cricut-ready, Silhouette-ready, vendor-certified or proof that a printer/cutter/material will work. Official vendor software can rescale externally saved PDFs and uses machine-dependent, non-rectangular cuttable areas; rebuild those constraints there and test physically.

Prepare your artwork before arranging it

Use a PNG with a transparent background when the outline should follow the artwork rather than a rectangular image boundary. Converting a JPG to PNG does not remove its background.

Need different pixel dimensions? Use the image resizer and crop tool before importing. The PNG, JPG and WebP converter can change supported formats, but cannot recover detail or invent transparency.
