500 KB is where smart compression shines — visually identical to the original for most photos, but half to a quarter of the file size. Great for email attachments, blog posts, and social media.
Frequently asked questions
Will viewers notice the difference?
Typically no. 500 KB is above the threshold where most compression artifacts are visible on a screen.
Good for blog posts?
Perfect. Most blog themes display images at 800–1200px wide — 500 KB is more than enough resolution for that.
What if I need smaller?
Try /to/100kb or /to/50kb for tighter targets.
