Frequently Asked Questions: 100KB Compression

Most email providers allow 20-25MB of attachments. That means you can include 200+ images at 100KB each in a single email without hitting limits.
Will 100KB images look good on retina displays?expand_more
For thumbnails and profile photos, yes. For hero images or full-screen displays, you may want a larger file size like 200KB or 500KB to maintain sharpness on high-DPI screens.
