How-to Guide

Combine PNG Images Online: Free Grid Tool, Lossless Export

PNG images with transparency (logos, icons, UI elements) need special handling when combined into a grid. MergeFrame preserves alpha channels, so your transparent assets stay transparent.

Try MergeFrame (Free)

PNG is the format for graphics needing transparency and sharp edges. But combining PNGs is tricky: many tools flatten transparency to white, introduce artifacts, or convert to JPG.

MergeFrame handles PNGs correctly: (1) Alpha channel preserved: transparent areas stay transparent. (2) Lossless export: mathematically identical to source pixels. (3) Resolution up to 4000px: the export ceiling, the same on every MergeFrame plan.

Use cases: combining app icons for press kits, merging UI components with transparent backgrounds, building logo walls (3×3 partner logos), assembling diagram exports into documentation images.

Pro tip: set a custom background color to preview how your transparent PNG grid will look on its target background.
