About Image Compressor
Oversized images are one of the biggest drags on page speed. Shipping a 2 MB hero when 200 KB would look identical wastes bandwidth and hurts your Core Web Vitals. The Image Compressor reduces file size with a quality control you adjust, so you decide the trade-off between weight and visual fidelity.
Upload an image, set the quality level, and the tool re-encodes it to a smaller file you can download right away. It's free, browser-based, and needs no account, so your images aren't stored on a remote server long-term. The result is delivered instantly, making it easy to test a few quality settings and pick the smallest file that still looks great.

FAQ
Is the compression lossy or lossless?
Lowering the quality setting applies lossy compression, which is why file size drops significantly. Higher settings preserve more detail at a larger size.
How do I find the right quality level?
Start around a mid-high setting and lower it until you notice quality loss, then step back up. The smallest acceptable file is usually the best choice.
Does it change the image dimensions?
No. Compression reduces file size without resizing. Use a resizer tool if you also need smaller pixel dimensions.
Can I use Image Compressor on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
