What is Reduce Image Size?
Reducing image size means lowering the file's kilobyte weight so it's easier to upload, email, or load on a page. You can do that by shrinking dimensions, compressing quality, or converting to a leaner format like WebP.

| PNG | Logos, graphics, text | Yes | 2–5× JPG |

Frequently Asked Questions
How do I make an image smaller?
Two ways: reduce dimensions (pixels) or compress quality. Our tool lets you do both for maximum reduction.
Best way to reduce size for a website?
Resize to the exact display width (usually 1200–1920px), compress at 70–80% quality, and convert to WebP for the smallest result.
Will reducing size affect quality?
Downsizing preserves quality; heavy compression may add slight artifacts. Keep quality at 70% or above for most uses.
