SVG is a text-based vector format for logos, icons, diagrams, charts, and responsive graphics. It scales cleanly because it describes shapes rather than fixed pixels, but it must be sanitized when accepting untrusted uploads.
SVG was developed by the W3C as an XML-based vector graphics language for the web.
Rasterize SVG to PNG when fixed-pixel compatibility is needed. Choose output dimensions, scale, background color, and font handling carefully.
SVG stays sharp at any size until rasterized. PNG/JPG outputs are fixed-pixel snapshots of the vector instructions.
SVG can contain metadata, embedded references, scripts, links, and text. Sanitize untrusted SVG and block external resource loads during conversion.
Strong browser and vector-editor support; rendering varies by fonts and features.

SVG transparency support is: alpha. Choose a target format with alpha support when transparent backgrounds matter.
Convert SVG when another format better matches compatibility, file size, transparency, metadata, or editing needs.
Missing fonts, external assets, CSS, or unsupported SVG features can change the rasterized result.
SVG is markup and may contain scripts or external references. Untrusted SVG should be sanitized before rendering.
Use the final display size or export at 2x/3x for high-density screens.
Use SVG where supported for scalable logos; use PNG as a fallback for fixed raster workflows.
