How PNG turns into PS: pixel tracing into approximate paths

The PNG pixel edges are traced into approximate shapes for PS. This is vectorization, not recovery of the designer's original paths, layers, fonts, or control points. PNG decoding combines filtered scanlines with declared color type, bit depth, palette or full alpha, color-profile chunks, and optional ancillary metadata. PostScript output is executable page-description code for a print interpreter; page devices, fonts, bounding boxes, color, and trusted processing conditions are essential.

Source material - Pixels written losslessly with a full alpha channel available. Rendered deliverable - A PostScript page-description program specifying text and graphics for printing or rendering.

OUTPUT MODEL

PS

PS vector graphic

Designed for path-based artwork meant to scale without pixelating.

Family: Vectors
MIME: application/postscript

When to actually choose PNG to PS

Use traced PS for simple flat marks that need scalable outlines. Photographs, texture, and evidence-grade source pixels belong in PNG or another raster master.

What changes between the PNG model and the PS deliverable

Alpha transparency that PNG can carry has no equivalent in PS; inspect how clear pixels are flattened.
PS expects scalable path data that a raster PNG source never recorded; any vector shapes in the result are traced approximations, not recovered geometry.
Treat PNG-specific metadata fields as optional in the PS result until you have actually confirmed they survived.

Acceptance evidence for the converted PS

BEFORE

Record the PNG evidence before conversion

Zoom to 100% on transparent edges, gradients, and small text, and confirm the exact pixel dimensions.

AFTER

Test the PS file in its receiving workflow

Process only trusted input in a sandbox and inspect page count, bounding boxes, fonts, colors, overprint, and printed rendering.

What the PNG source carries and the PS output demands

PNG

What can fail when Portable Network Graphics is interpreted

PNG is a poor fit for photographic detail, and even without any JPEG-style loss, palette reduction can visibly simplify a smooth gradient.

What PS vector graphic cannot safely promise

Executing untrusted PostScript is unsafe, and missing fonts, device assumptions, page boxes, or color setup can change output.

How the PS writer handles this route

a PostScript page-description program specifying text and graphics for printing or rendering is what gets written, labeled as application/postscript. Whether that actually opens depends on the receiving application, not on the file extension.
