Best Image Format for Transparent Logos
Logos need transparency to float cleanly over different backgrounds — website headers, email footers, dark mode, and printed materials all use different background colours. Choosing the wrong format means white boxes around your logo or quality loss at different sizes. This guide tells you exactly which format to use in each context.

Remove the background first
If your logo has a white or coloured background, remove it using the Background Remover tool. This gives you a clean logo with a transparent background — the base you need for any transparent format.
For web use — use PNG-24 or WebP
PNG-24 supports full alpha channel (semi-transparent edges for anti-aliasing). It's universally supported in all browsers and email clients. WebP is 26% smaller than PNG with identical quality — use WebP for websites. Use PNG as the fallback.
For scalable use — use SVG
If your logo is vector-based (Illustrator, Figma, Sketch), export as SVG. SVG logos scale to any size without quality loss, display sharply on any screen, and are typically under 20KB. SVG is the best format for logos used at multiple sizes (favicon, header, footer, print).
For email use — use PNG
Email clients have inconsistent support for WebP and SVG. PNG-24 is the safest choice for email signatures and email marketing. At 300px wide, a PNG logo with transparency is typically under 30KB.
For print — use PDF or EPS (vector) or PNG at 300 DPI
Print requires vector (PDF, EPS, AI) for clean scaling. If only raster formats are accepted, use PNG at 300 DPI at the required physical dimensions. A 3-inch wide print logo at 300 DPI = 900px wide PNG.

Pro tip
Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.
