Why Use an Image Compressor?
Large images slow down websites, increase bandwidth usage, and hurt Core Web Vitals. A good image compressor reduces file size while keeping enough visual quality for blogs, landing pages, portfolios, ecommerce pages, and social posts.
How to Get Smaller Images
- Use WebP for most website images because it usually creates smaller files than JPG or PNG.
- Resize large photos before uploading them to a blog or CMS. Most article images do not need to be wider than 1600 pixels.
- Lower quality gradually until the file is small but still looks clean on your target screen size.
- Keep PNG only when needed for transparency, icons, screenshots, or sharp interface graphics.
Frequently Asked Questions
Is this image compressor free?
Yes. It is free, runs in your browser, and does not require an account.
Are my images uploaded?
No. The file is processed locally with browser APIs, so the image stays on your device.
Can I resize and compress at the same time?
Yes. Set maximum width and height, choose an output format, adjust quality, and the tool will resize and compress in one step.
What quality setting should I use?
For web images, 70 to 82 percent is a good starting range. Use a higher setting for detailed product photos and a lower setting for large background images.
