PSD to SVG (PNG raster inside): an XML viewport around a flattened bitmap—great for embedding, not automatic vectorization
Here the SVG is a lightweight wrapper: the Photoshop “visible merge” composite (often PNG) is embedded in `<image>` with `viewBox` and width/height so wikis, review pages, and component docs can reference one MIME type. Pixel detail is still bounded by the embedded bitmap—zooming past real pixels will look blocky, which is unrelated to “infinite vector scaling.” Collaboration needs an explicit line: this is preview or placeholder art, not an editable vector source; copy and shape edits belong in PSD, Figma, or Illustrator. Also watch CSP, hotlinking, and inline weight: stuffing a huge PNG as base64 into HTML can wreck TTFB—usually prefer a fingerprinted static URL with cache headers.
How to use PSD to SVG online: freeze visible layers, upload, download an SVG that wraps the PNG, compare aspect ratio and sharpness against the merged PSD view in a browser, then archive version and hash with the ticket
- In Photoshop confirm outward-visible layers, artboard pixel size, and that the export long edge covers target CSS width times device DPR; hide review markup. If the site forbids remote images, decide upfront between inline data URIs and same-origin static paths so Content-Security-Policy does not block production.
- Open the downloaded SVG directly in a browser and again inside the target page via `<img>` or iframe; check that `viewBox` plus CSS scaling does not stretch unexpectedly. Zoom to 200%—if small type or hairlines soften, raise merge resolution or interpolation in PS; the SVG shell will not invent detail.
- Store the SVG next to the source PSD, parameter notes, and a file hash in the same release record; use fingerprinted URLs in component libraries so long-lived CDN caches do not keep showing an old thumbnail after design updates.
PSD to SVG FAQ (raster-in-SVG, not path reconstruction)
Stakeholders see “SVG” and assume icon-style CSS `fill` or path surgery—how do we draw a hard boundary versus real vector deliverables?
State plainly: this SVG is a preview wrapper whose hero lives in the embedded PNG referenced by `<image>`; it does not ship independent vector outlines or live text objects. Vector sourcing must follow your design-system or desktop export process. Without that sentence, front-end teams wire it like a glyph component, then blame the converter when colors and strokes cannot be edited.
The asset looks crisp on a Retina laptop but soft on a standard display or after CSS scale—does that mean SVG failed, or is it just embedded resolution versus layout math?
Inspect `naturalWidth` versus CSS width and devicePixelRatio, and check for non-integer transforms. Problems almost always trace to insufficient embedded pixels or layout stretch, not broken SVG syntax. A/B against a PNG exported at the same merged size from Photoshop to separate source resolution from container mistakes.
Should the embedded PNG be base64-inlined or referenced by URL—what are the usual trade-offs for performance, caching, and SEO hygiene?
Inlining balloons HTML, hurts cache reuse, and can damage TTFB; external fingerprinted static files with long cache headers fit most site embeds. Reserve base64 for tiny badges, strict single-file archives, or email-like bundles where a second request is impossible—never silently drop a multi-megabyte preview into the document head.
Security or compliance worries about scripts and remote loads—how do we describe the threat model for these raster-wrapped SVGs and harden delivery?
Well-formed outputs should be static `<svg>` plus `<image>` without `<script>` or external entities; still run policy scans, block untrusted uploads from hot paths, and hash frozen builds. If users can upload arbitrary SVG, you need sanitization and tag allow-lists—your generator being static does not immunize the whole product surface.
Can this SVG go straight to press or large-format print as the final mechanical?
Usually no: the wrapper targets screen collaboration, and embedded resolution may not meet print line screens, bleed, spot colors, or font embedding rules. Keep press on TIFF/PDF/Illustrator workflows and label tickets “not a print master.” Sending this file to a vendor without that disclaimer invites expensive replating and liability fights.
