Everything You Need to Build Gang Sheets

GangOwl packs professional layout tools into a free, browser-based workspace. No downloads, no accounts, no learning curve.

Layout

Auto-Place Algorithm

Automatically arrange designs onto your sheet with a bin-packing algorithm that minimizes wasted space. Supports configurable spacing between items and respects your chosen sheet dimensions.

Production

Die-Cut Contour Lines

Generate CutContour paths around your designs for use with cutting plotters and print-and-cut workflows. Contours follow the shape of your artwork with adjustable offset distance.

Workflow

Multi-Sheet Distribution

When your designs exceed a single sheet, GangOwl automatically distributes them across multiple sheets. Each sheet is independently exportable and maintains the same dimensions and settings.

Precision

Smart Guides & Snapping

Align designs precisely with smart guides that appear as you drag items across the canvas. Snap to edges, centers, and other elements for pixel-perfect placement every time.

Export

PNG, JPEG, WebP & PDF

Export your finished gang sheets in the format your workflow demands. Set custom DPI values from 72 to 600 for print-ready output. PDF export preserves vector-quality contour lines.

Editing

Cut Lines & Visual Guides

Add registration marks and visible cut lines to your exported sheets. Toggle them on or off depending on whether your cutter reads them from the printed output or from a separate file.

Import

Drag & Drop Upload

Add designs by dragging image files directly onto the canvas. Supports PNG, JPEG, WebP, and SVG formats. Each image can be individually resized, rotated, duplicated, or removed.

Control

Custom DPI & Sheet Sizes

Choose from common DTF film sizes (13x19, 22x24, A3, A4) or enter custom dimensions in inches or centimeters. Set your target DPI to match your printer's native resolution.


How It Works

Three steps from artwork files to a production-ready gang sheet.

1

Upload Your Designs

Drag and drop your artwork files onto the canvas or use the file picker. PNG files with transparency work best for DTF and vinyl workflows.

2

Set Your Sheet Size

Pick a standard film size or enter custom dimensions. Configure spacing, DPI, and whether you need die-cut contour lines for your cutter.

3

Auto-Place & Export

Hit the auto-place button to fill your sheet efficiently. Fine-tune positions if needed, then export as PNG or PDF at your chosen resolution.


Built for Print Professionals

GangOwl is designed for anyone who arranges multiple designs onto a single sheet before printing or cutting.

DTF Printers

Maximize film usage by fitting as many transfers as possible onto each sheet. Export at 300+ DPI for sharp, detailed prints on DTF film.

Sublimation Shops

Lay out sublimation transfers for mugs, tumblers, shirts, and more. Reduce paper waste by ganging multiple designs on a single press sheet.

Vinyl Cutters

Arrange heat transfer vinyl designs with proper spacing for weeding. Export with contour lines so your plotter cuts each design precisely.

Sticker Makers

Create sticker sheets with die-cut outlines around each design. Print on sticker paper and use a cutting machine for professional results.
