Big image files slow down websites, fill up storage, and get rejected by upload limits. Here are three free ways to compress an image online — fastest first — without making it look bad.
1. Resize the dimensions
The biggest, easiest win. An image at 4000px wide is wildly larger than the same image at 1200px. Use the Resize tool to scale it down to the size you actually need.
2. Convert to a modern format
WebP and AVIF compress far better than JPG or PNG. Converting can cut the file by 50–90% at the same visible quality — try WebP or AVIF. See the best format for websites for which to pick.
3. Crop out what you don’t need
Trim dead space with the Crop tool so you’re only storing the part that matters.
FAQ
Will compressing lower the quality?
Resizing and converting to WebP/AVIF keep quality high. Most visible loss comes from over-enlarging later, not from shrinking.
Is it free?
Yes — free, no watermark, no sign-up.
