1MB is the typical email attachment limit and a common cap on CMS uploads (WordPress media library defaults, for instance). It's also a comfortable size for high-resolution archival photos that need to stay portable.
ImageMint's binary search finds the optimal quality to fit exactly 1024KB or less, preserving as much detail as possible. Choose WebP for the best quality-per-byte.
