Image Compressor
Choose an image, adjust quality and size, download the result. The file never leaves your browser — there's no upload step, so this works even on huge images without a wait.
Tips for smaller images
80% quality on JPEG or WebP is usually visually indistinguishable from 100% but meaningfully smaller. WebP typically beats JPEG at the same visual quality, but check that your CMS/browser support requirements allow it. Resizing to the actual display width (rarely does a blog need a 4000px-wide photo) usually saves far more than quality tweaks alone.
How to use the Image Compressor
- Choose an image from your device.
- Pick WebP or JPEG, set quality around 75–80%, and optionally a maximum width.
- Compare the result and download it if it is smaller.
Frequently asked questions
What quality setting should I use?
75–80% is usually indistinguishable from the original on screen and much smaller. Resizing to the display width often saves even more.
Why is the compressed file sometimes bigger?
Simple graphics and already-optimised images can grow when re-encoded. The tool warns you so you can keep the original.
Are my images uploaded?
No. Compression runs on your device using the browser’s canvas, so private images never leave your computer.
