Clean Transparency Flattening onto Solid Page Background

Standard PDF document viewers do not support raw transparent alpha channels uniformly across print and digital readers, often rendering transparent areas as solid black blocks.

NexoPixel automatically composites your transparent PNG graphics over a crisp solid white background (or custom page background) during compilation, eliminating black artifact blocks and dark halo edges.

Combine Multiple PNGs with Drag & Touch Reordering

Merge receipts, graphic designs, charts, and diagrams into a unified multi-page PDF document. Arrange pages seamlessly using touch-friendly Move Up and Move Down buttons designed with full mobile touch-target accessibility.

Select from standard document formats including A4, US Letter, US Legal, or Auto (Fit Image), and adjust uniform margins to match your layout or printing preferences.

100% In-Browser Privacy & Security

Your PNG images never leave your computer or phone. All canvas compositing, page geometry calculations, and PDF 1.4 binary assembly execute strictly inside your local web browser.
