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. Compressing images before publishing them can help reduce page weight and make images faster to transfer, especially for visitors using slower connections or mobile networks.
- Faster page load times, especially on mobile networks
- Lower bandwidth and hosting costs for high-traffic sites
- Make image-heavy pages lighter.
- Prepare smaller images before uploading them to a CMS.
- More storage-efficient photo libraries and backups

Who Uses Image Compression?
Compress JPG, PNG, and WebP Images
Compress JPG Images
JPG compression is useful for photographs, product images, and other images with many colors. Adjusting the quality can significantly reduce file size while keeping the image visually sharp.
Compress PNG Images
PNG files are commonly used for graphics, screenshots, logos, and images that need transparency. Compression can make large PNG files easier to store, upload, and share.
Compress WebP Images
WebP is widely used for web images. Compressing WebP files can further reduce the amount of data a browser needs to download.
What Image Compression Quality Should You Use?
The right quality level depends on how the image will be used. Higher quality generally preserves more visual detail, while lower quality produces a smaller file.
- 80–100%: Useful when preserving fine details is the priority.
- 60–80%: A practical range for many website and general-purpose images.
- 10–60%: Useful when reducing file size is more important than maximum image detail.
The best setting depends on the original image, its dimensions, and where it will be used. Preview the result before downloading to find the right balance.
