Why Compress Images?
Large images slow down websites, increase storage costs, and use unnecessary mobile data. Compressing images to the smallest acceptable file size improves page load times, boosts SEO rankings, and provides a better experience for your visitors.
Google's Core Web Vitals score penalises pages with oversized images. A compressed JPG at 80% quality is visually identical to the original but can be 60% smaller — a huge win for performance with no visible trade-off.
Frequently Asked Questions
Does image compression reduce quality?
It depends on the compression level. At 80% quality, most images look identical to the original but are 40–70% smaller. At 60% quality, you may notice very slight softness. Our tool lets you choose the quality level so you stay in control.
Is my image uploaded to a server?
No. SwiftToolAI's image compressor runs entirely in your browser using the Canvas API. Your image never leaves your device.
What image formats can I compress?
You can compress JPG, PNG, and WebP images. The output is always saved as JPG for maximum compatibility and smallest file size.
What is the maximum image size?
There is no server-side limit because compression happens in your browser. Very large images (over 30MB) may take a few seconds to process depending on your device.
