About This Image Compressor
Image compression reduces the file size of images while maintaining acceptable visual quality. Smaller images load faster, use less bandwidth, take up less storage space, and improve the user experience on websites and apps.
There are two main types of image compression: lossless and lossy. Lossless compression reduces file size without losing any quality —the original image can be perfectly reconstructed. Lossy compression achieves smaller file sizes by selectively discarding some image data that the human eye is less likely to notice.
Image file formats use different compression methods. PNG is lossless and good for images with text or sharp edges. JPEG is lossy and best for photographs. WebP is a newer format that supports both lossy and lossless compression and generally achieves better compression than both PNG and JPEG.
Using an image compressor before uploading images to your website or sharing them online can dramatically reduce file sizes with little to no visible quality difference. This improves page load times, reduces bounce rates, and saves bandwidth costs.
Frequently Asked Questions
How does image compression work?
Our tool uses your browser's Canvas API to re-encode images at a lower quality setting. For JPEG and WebP formats, this reduces file size significantly with minimal visible quality loss. PNG images are converted to JPEG/WebP for better compression. You can adjust the quality slider to find the right balance between file size and visual quality.
Are my images uploaded anywhere?
No! All image processing happens entirely in your browser using JavaScript and the Canvas API. Your images never leave your device. This makes it completely private and secure, even for sensitive images.
What quality should I use?
For most web use, 70-85% quality is a good balance. 80% is our default and produces great results with significant file size reduction. For photos where quality is critical, use 90%+. For thumbnails or background images where small file size matters most, try 50-70%.
