Open the PNG at 100 percent and inspect one-pixel strokes, diagonal edges, small type, filters, and transparent padding. Thin lines aligned between pixel boundaries can look softer than expected even at an adequate size. Adjusting the SVG geometry or exporting at a larger integer multiple can improve the displayed result.
Canvas-based output creates a new raster file and does not preserve SVG source markup, element names, accessibility text, animation, or editing structure. Metadata and ICC profile handling depend on the browser and output. Archive the SVG, document the chosen raster dimensions in the filename, and treat the PNG as a destination-specific snapshot.
Allow for the destination's safe area as well as its nominal dimensions. Profile images and app icons are often clipped into circles or rounded shapes, while marketplace thumbnails may add their own padding. Preview those masks before export so important strokes and lettering do not sit against the edge. If the SVG carries meaningful text or a diagram description, move that information into nearby HTML, document captions, or alternative text because rasterization removes the vector's accessible structure. For repeated exports, record the width, height, background choice, and intended slot. That simple specification makes the PNG reproducible and prevents later contributors from scaling an old bitmap when they should rasterize the SVG again.
