Best Practice: High-Resolution PNG for Emails
Export PNG at 2× your display size for Retina-sharp quality without SVG.
- Logo at 200px wide in email → export PNG at 400px wide (2×)
- Use: <img src='logo.png' width='200' height='50' alt='Logo'>
- Always set width and height HTML attributes — prevents layout shift
- PNG logo is visually indistinguishable from SVG at 2× on Retina screens
- This is the standard approach used by every major email service provider
Frequently Asked Questions
Can I use SVG in email signatures?
Avoid it. Most business email clients (Outlook) don't render SVG. Export your SVG logo as PNG at 2× size for email signatures. Host the PNG image on a stable CDN for reliable display.
Does Gmail support SVG?
No. Gmail strips SVG images from emails. Always use PNG or JPG for Gmail-addressed emails.
Can I use CSS-animated SVG in email newsletters?
No. CSS animations in SVG don't work in email clients. Use animated GIF for email animation.
How do I get a vector-quality logo in an HTML email?
Export SVG as PNG at 2× the display size. Use srcset if your ESP supports it: <img src='[email protected]' width='200'>. The 2× PNG is indistinguishable from SVG at typical email viewing sizes.
Do email design tools like Mailchimp or Klaviyo support SVG?
Mailchimp and Klaviyo accept SVG uploads but automatically convert them to PNG for cross-client compatibility. You can upload SVG — these platforms handle the fallback.
