How to Compress an Image for Without Losing Quality

How to Compress Images Without Visible Quality Loss

Most image compression tools apply a fixed quality setting — often too aggressively — which results in visible JPEG artifacts: blocky edges, color distortion, and loss of fine texture. Our tool takes a different approach. It uses a binary-search quality algorithm that starts at high quality and progressively tests lower settings, stopping at the highest quality that produces a file under the target size. This means you always get the maximum quality possible for the given file size, rather than a one-size-fits-all compression level. The sweet spot for visually lossless compression is highly dependent on the image content. Photos with smooth backgrounds and large flat areas compress much better than detailed textures. Our algorithm accounts for this automatically by testing each image individually rather than applying a preset. The result is consistently sharper than manual Photoshop compression at equivalent file sizes. At 200KB — our default target — most photos look visually identical to the original at normal viewing distances on screen. The entire compression process runs in your browser, so your original image is never sent to any server.
