Image Compression
Reduce the file size of your JPG, PNG, and WebP images without compromising visual quality. Whether you're optimizing for web performance, saving storage space, or preparing assets for mobile, PixyTools makes it fast, free, and effortless — entirely inside your browser.
Why Compress Your Images?
Large, uncompressed images are one of the most common reasons websites load slowly. Every extra megabyte adds delay, hurts your Core Web Vitals score, frustrates visitors on mobile data, and can even affect your search engine ranking. Compressing images strikes the right balance — cutting file size dramatically while keeping the visual quality your users expect.
- Faster page load times, especially on mobile networks
- Lower bandwidth and hosting costs for high-traffic sites
- Better SEO performance, since page speed is a ranking factor
- Smaller email attachments and faster uploads to CMS platforms
- More storage-efficient photo libraries and backups

What image formats are supported? JPG, PNG, and WebP are currently supported, covering the vast majority of images used on the web today.
Will compression reduce image quality? You control the quality level with a simple slider. Lower settings save more space; higher settings preserve more detail. Most users find 70–85% quality gives an excellent balance between file size and visual fidelity.
Is there a file size or file count limit? You can compress up to 6 images at once in this browser session, completely free with no sign-up required.
