SVG vs PNG for Email Signatures
Why PNG remains the safer choice for email signature logos despite SVG's sharpness.
Email Client Support Gaps
Many email clients (notably some Outlook versions) don't render inline SVG reliably, while PNG with transparency is universally supported. For email signatures specifically, PNG remains the safer default despite SVG's crispness advantages elsewhere.
- Outlook and other clients have inconsistent SVG support
- PNG with transparency renders reliably everywhere
- SVG's sharpness advantage doesn't matter if it won't render
Best Practice Workflow
Design your signature logo as SVG for crispness during design, then export a high-resolution PNG (2x for retina displays) specifically for embedding in email signatures.
- Design the logo in SVG, export PNG for email use
- Export at 2x resolution for retina display clarity
- Keep file size small to avoid slowing email loads
Frequently Asked Questions
Why shouldn't I use SVG directly in an email signature?
Several email clients, including some Outlook versions, don't reliably render inline SVG, so a universally supported PNG is the safer choice for signatures.
What resolution should an email signature logo PNG be?
Export at 2x the display size so the logo looks sharp on retina/high-DPI screens, while keeping file size reasonably small.
