4. 4

   Download and use as your WhatsApp avatar, email signature image, or favicon source.

WhatsApp profile photos are displayed at tiny dimensions and benefit from files around 30KB — small enough to load instantly on 3G connections, large enough to stay recognizable. Email signature images embedded in Outlook, Apple Mail, and Thunderbird templates should also stay under 30KB so they do not bloat every outgoing message. Favicon source files destined for conversion to .ico format work best at this weight too. Many lightweight CMS avatar systems and comment-platform profile pictures (Gravatar, Disqus) render at 30KB-class sizes internally.

• For email signatures, keep dimensions around 100x100 or 200x50 pixels before compressing to maximize sharpness at 30KB.

• Square-crop profile photos before compressing — most platforms will crop to a circle, so center the subject carefully.

• If your image has transparency (logos), consider PNG at this size; for photos, JPEG is more efficient.

Will my image lose quality when compressed to 30KB?

SizeSnap uses smart compression that minimizes visible quality loss. For 30KB, some quality loss is expected, but SizeSnap optimizes to keep the image looking good at this size.
