Frequently Asked Questions

Common questions about our Image Compressor.

Image compression reduces file size by removing redundant data and applying encoding algorithms. For JPEG images, the compressor uses lossy compression that discards visual information the human eye is less sensitive to, such as subtle color variations. For PNG, it applies lossless optimization to reduce file size without any quality loss. WebP uses advanced compression techniques that achieve smaller files than both JPEG and PNG at equivalent quality. All processing happens entirely in your browser using the HTML5 Canvas API — your images are never uploaded to any server.
It depends on the format and quality setting you choose. JPEG and WebP use lossy compression, which means some visual detail is discarded to achieve smaller files. At quality levels of 70-90, the difference is virtually imperceptible to the human eye while achieving significant file size reductions of 50-80%. PNG compression is lossless, meaning no quality is lost at all. The built-in before/after comparison lets you visually inspect the result so you can find the perfect balance between file size and quality for your needs.
This tool supports the three most popular web image formats: JPEG (JPG), PNG, and WebP. You can upload images in any of these formats and choose to output in the same format or convert between them. JPEG is ideal for photographs with many colors, PNG is best for graphics with transparency or sharp edges, and WebP offers superior compression for both types of content. The Auto output option keeps the same format as your original file.
Since all processing happens locally in your browser, there is no server-imposed file size limit. You can compress images of any size, though very large images (above 50MB or extremely high resolution) may take longer to process depending on your device capabilities. You can upload up to 10 images at a time for batch processing. For optimal performance, we recommend working with images under 25MB each.
No, your images never leave your device. This tool processes everything entirely in your browser using the HTML5 Canvas API and JavaScript. No image data is transmitted over the internet, stored on any server, or accessible to anyone else. This makes it completely safe for compressing sensitive, private, or confidential images. You can even use it offline once the page has loaded.
Yes, this image compressor is 100% free with no limits on usage. There are no watermarks added to your images, no sign-up required, and no premium tier. You can compress as many images as you need, as many times as you want. The tool works on all modern browsers across desktop and mobile devices without any software installation.
