How WMF turns into PNG: rasterization at a fixed canvas

Rasterizing WMF fixes every path and shape onto one pixel grid before that canvas is encoded as PNG. Once that happens, scaling the derivative back up cannot recover the original curves. WMF input replays legacy GDI records with device-dependent mapping, font selection, clipping, pen and brush state, and integer coordinates onto the destination canvas. PNG delivery preserves exact raster samples with optional full alpha and color metadata, but file size, palette reduction, animation absence, and profile handling still vary.

Source material - A legacy Windows Metafile storing GDI drawing records with limited modern graphics capabilities. Rendered deliverable - Losslessly encoded pixels with full alpha transparency.

When to actually choose WMF to PNG

Use PNG when the destination needs pixels; keep WMF for logos, diagrams, or print work that must remain resolution independent.

What changes between the WMF model and the PNG deliverable

PNG supports alpha transparency that WMF never had, so any transparent areas in the result are newly created, not carried over from the source.
Scalable WMF paths become a fixed-resolution PNG pixel grid; choose dimensions before delivery.
WMF and PNG use different metadata conventions, so application-specific fields should be treated as optional until verified.

Checking the PNG result before you trust it

BEFORE

Record the WMF evidence before conversion

Render at multiple sizes and inspect bounding box, line widths, text metrics, clipping, fills, colors, and orientation.

AFTER

Test the PNG file in its receiving workflow

Inspect transparent edges, gradients, exact dimensions, color, and small text at 100%.

What the WMF source carries and the PNG output demands

WMF

What can fail when WMF vector graphic is interpreted

Coordinate precision, fonts, clipping, color, and device-dependent records can render differently outside Windows.

PNG

What Portable Network Graphics cannot safely promise

PNG is inefficient for many photographs, and indexed optimization can reduce a smooth palette even without JPEG-style loss.

How the PNG writer handles this route

The writer builds losslessly encoded pixels with full alpha transparency and labels the result as image/png. The receiving application - Not the extension alone - Is the final compatibility test.
