What does converting SVG to PNG actually do?
SVG describes shapes, paths and text mathematically rather than as a pixel grid, so a single file renders crisply from a favicon to a billboard. Because it is XML it can be styled with CSS, animated and searched — but it cannot represent photographic detail. PNG stores pixels losslessly, so an image survives any number of edit-and-save cycles without degrading, and it carries an 8-bit alpha channel for genuine transparency. That fidelity is why it is the standard for logos, icons, UI screenshots and any graphic with sharp edges or flat colour. Converting SVG to PNG therefore re-encodes the same content under a different set of rules — the pixels are decoded from the source image and written out through the destination encoder. Nothing is uploaded: the decode-and-re-encode cycle happens on your own machine.
