SVG TO PNG FOR EMAIL SIGNATURES

How do I make an SVG logo work in an email signature?

Export your logo as a PNG at the intended display proportions, add it to your signature, and send a test email to another inbox. Check the received message on a narrow screen and against light and dark backgrounds. Conversion makes a raster file; it does not guarantee that a particular mail app will display or resize it the same way.

Convert your SVG to PNG

DISPLAY SIZE

Keep the logo's proportions

Start with the signature layout, not an arbitrary export preset. If the displayed logo should be 160 by 40 CSS pixels, a 320 by 80 PNG has twice as many source pixels along each side while keeping the same 4:1 aspect ratio. That is an example calculation, not a rule imposed by email clients. Check how your signature editor handles image dimensions before relying on a particular display size.

Received result	Thing to inspect	What to change in your source or layout
Logo is tiny inside a large rectangle	Empty space in the SVG viewBox	Crop a copy of the SVG canvas around the visible logo, preserving deliberate breathing room.
Logo fills the whole message width	Image display dimensions in the signature editor	Set the intended display width there, or use an appropriately sized PNG when the editor provides no reliable control.
Fine text is illegible	Actual display size in the received message	Use a simpler logo variant; exporting more pixels cannot preserve details that shrink below readable size.
Mark disappears on a dark background	Dark artwork on a transparent PNG	Test a contrasting logo variant or use a deliberate solid background, then inspect both light and dark views.

CONTROLLED EXAMPLE

Try a wide mark before using your own

Paste this complete SVG into the converter and choose a custom width of 320 while keeping the ratio. The expected output is 320 by 80 pixels because its viewBox is 320 by 80. It contains no external font or image, so this test isolates sizing and background behavior from linked resources.

<svg xmlns="http://www.w3.org/2000/svg" width="320" height="80" viewBox="0 0 320 80">
  <rect x="8" y="8" width="64" height="64" rx="12" fill="#087f8c"/>
  <path d="M27 40l10 10 18-21" fill="none" stroke="#fff"
        stroke-width="7" stroke-linecap="round" stroke-linejoin="round"/>
  <rect x="90" y="23" width="176" height="12" rx="6" fill="#172033"/>
  <rect x="90" y="45" width="116" height="8" rx="4" fill="#ed5b2d"/>
</svg>

The sample uses shapes instead of letters so a missing local font cannot change its appearance. Its dark bar intentionally makes a transparent export vulnerable to dark-background contrast; compare the transparent output with a solid-background export. Do not treat this sample as an email-client compatibility test.

REAL MESSAGE TEST

Inspect the received signature, not just the download

Make a copy of your SVG and check its viewBox, visible padding, and any externally loaded fonts or images.
In the converter, paste the SVG or select the file. Set Custom width, leave Keep ratio on, and choose a transparent or solid background based on your design.
Download the PNG, open it, and confirm its pixel dimensions and contrast before adding it to your email signature.
Send a message to a separate inbox. View the received email on desktop and mobile, with light and dark appearance if available. Check that the logo is visible, proportionate, and not oversized.
If the received image differs, change the signature editor's image sizing or revise the SVG artwork, then send another test. This converter makes one PNG at a time; it does not install a signature or host the image.

Privacy check: The SVG-to-PNG conversion happens in your browser. Once you add the resulting PNG to an email signature, your email service and recipients handle that image under their own rules.

FAQ

Email signature export questions

Will transparent PNG look correct in dark mode?

Not always. A dark mark can blend into a dark message background. Test the received email and consider a logo variant with built-in contrast or a deliberate background.

Does a larger PNG force the recipient to see a larger logo?

No. File dimensions and displayed dimensions are different. Your signature editor and the recipient's mail app can affect the final display.

Can this tool add a clickable link to my signature?

No. It exports an image. Set any link in your email signature editor, then send a test message to verify it.

Export the logo, then test a real email.
