SVG to PNG Converter

SVG is an XML format that stores graphics as mathematical geometry. PNG is a lossless raster format that stores a fixed pixel grid. Converting SVG to PNG rasterises the vector geometry at the pixel dimensions you choose, producing an image that can be opened by any application without SVG support.

This converter reads the SVG in the browser, parses its declared dimensions, and rasterises to a lossless PNG using the Canvas API. No file is uploaded at any point.

Why PNG Over WebP for SVG Rasterisation

PNG is the most universally accepted lossless image format. It is supported natively by every image editor, operating system viewer, design tool, CMS, and email client in active use. Platform upload validators that block SVG for security reasons almost always accept PNG without restriction.

Lossless encoding preserves every pixel at the quality set by the output dimensions you specify. There is no compression artefact to worry about on sharp edges, text characters, or flat colour regions. For logos, icons, and diagrams, lossless output ensures the rasterised PNG is a pixel-accurate representation of the SVG at the chosen size.

WebP provides smaller file sizes than PNG for the same visual content, but requires a browser capable of rendering WebP — a consideration in email templates, legacy CMS integrations, and some desktop software. PNG has no such dependency.

SVG vs PNG: Format Characteristics

Choosing Output Dimensions

The converter reads the SVG’s width, height, and viewBox attributes and prefills those values as the default output dimensions. SVG is resolution-independent, so the output resolution is your choice — the converter will rasterise the geometry at any pixel size you specify.

For email use, match the display size precisely — email clients do not scale images down gracefully and may show a blurred result if the PNG is larger than its container. For social media, match the platform’s specified pixel dimensions. For print-adjacent digital contexts, use at least 144 pixels per inch at the intended display size to support high-DPI screens.

Enabling the lock ratio checkbox preserves the SVG’s original proportions when you change either dimension. Unlocking it allows deliberate distortion of the output geometry.

Transparency in SVG to PNG Conversion

PNG preserves alpha channel transparency from the SVG source. The Canvas API renders the SVG with its original transparent regions intact, and PNG’s lossless encoding stores those alpha values exactly. Logos, cut-out shapes, and icons with transparent backgrounds convert correctly without requiring a white background fill.

How the Converter Works

The SVG file is read as text. The parser extracts the declared width, height, and viewBox to determine source dimensions. A Blob URL is created from the SVG text and used to render the graphic in a browser Image element. That element is drawn to an HTML Canvas at your specified output dimensions, and the canvas pixel data is exported as a lossless PNG.
