Why signature photos need transparency
An email signature is rendered against whatever background the recipient happens to be using: white in most webmail, near-black in dark mode, and something different again once your message is quoted inside a reply. A headshot with a white rectangle baked into it looks correct in the first case and like a floating white box in the others.
A transparent PNG fixes this because the background is absent rather than white, so the photo simply takes on whatever colour sits behind it. Clear Canvas removes the background from your headshot locally in your browser, which matters more than usual here — a signature photo is a picture of you, and it never leaves your device.
Sizing and format for email clients
Use PNG. Transparency support across email clients is far more consistent for PNG than for WebP, and several desktop clients still will not render WebP at all. Keep the image small — roughly 100 to 150 pixels on its long edge at display size, exported at twice that for high-density screens — because a signature image is downloaded with every message you send, and some corporate mail gateways strip images over a size limit.
What to watch for in signature headshots
- Flyaway hair against a busy office background is the usual failure point. A photo taken against a plain wall cuts far more cleanly.
- Glasses with strong reflections blur the boundary between face and background, and edges can wander as a result.
- If your signature will only ever appear on white, you may not need transparency at all — a plain white background is simpler and produces a smaller file.
- Dark clothing against a dark background gives the model little to separate on, and the cutout may clip your shoulders.
