Large image files slow down web pages, take longer to send, and consume unnecessary storage. Compressing images reduces their file size without visibly degrading quality — making them faster to load and easier to share.
i2img uses smart lossy and lossless compression algorithms that strip metadata and redundant data while preserving the pixels that matter most to human vision. The result: smaller files that look identical to the original.
