Sketch Clean

Turn notebook sketches into crisp line art on a transparent background — ready for colour, lettering, or finishing in your favourite art app. No more grey paper texture or smudged pencil fill: Sketch Clean isolates your lines so you can work digitally without redrawing from scratch. Private by design: processing stays on your device — no upload, no account, no analytics. HOW IT WORKS - Photograph your sketch or pick one from your photo library - Sketch Clean detects the page, corrects perspective, and removes paper tint and shadows - Your clean line art is ready on a transparent background in seconds FEATURES - Transparent PNG export — lines on alpha, ready to layer in Procreate, Clip Studio, Photoshop, or any digital art tool - "On White" export — share a white-background version that looks great anywhere - Automatic page detection and perspective correction — no manual cropping needed…
