Compress Image Online Free
Shrink JPG, PNG, and WebP file sizes for faster websites, smaller uploads, and easier sharing.
Large images are the number-one cause of slow web pages and rejected uploads. Compressing an image lowers its file size — often by more than half — while keeping it looking great. Media Manipulator compresses your JPG, PNG, or WebP at the quality you choose, defaulting to a balanced 80. Free, online, no signup.

- For photographic content, switching the output to WebP usually beats JPG file size at the same quality.
- PNG is lossless: to shrink a PNG photo substantially, convert it to JPG or WebP rather than just lowering quality.

Frequently asked questions
How do I compress an image for free?
Upload your image, lower the quality value (75–85 is a good start), and click convert. The compressed image downloads instantly. It is free with no signup.
Does compressing an image reduce quality?
Slightly — compression is a trade-off. At quality 75–85 the change is usually invisible. Lower the quality further only when you need the smallest possible file.
How do I compress a PNG?
PNG is lossless, so the biggest savings come from converting a photographic PNG to JPG or WebP. For graphics, WebP lossless can also help.
What is the best format for small image files?
WebP usually gives the smallest files at a given visual quality. JPG is a close second for photos and is more universally compatible.
Are my uploads stored?
No. Files are processed on our own servers and deleted within 24 hours. No account is required.
