About Image Compressor
The Image Compressor is an online tool for lossless and lossy image compression. High-definition original images usually have large file sizes, which cause slow web loading, upload timeout, excessive storage occupation and slow transmission. This browser-based tool requires no client software and supports mainstream formats such as JPG, PNG and GIF. It provides adjustable compression levels: high compression rate for maximum size reduction and low compression rate to keep original image quality. It processes single or multiple images in batch. All compression operations run locally in the browser without uploading original images to external servers to protect privacy. It displays size comparison and visual preview before and after compression, and users can download processed images singly or in bulk.
How Image Compressor works
High-resolution images have rich details but large file sizes, which bring troubles to upload, transmission and storage. Most platforms have file size limits for uploaded images, and large images often fail to pass. A large number of big images will slow down web and APP loading and damage user experience.
Traditional compression methods have many disadvantages. Professional image editing software has complex operations and requires professional knowledge, which is hard for ordinary users. Built-in system tools have limited compression effect, no adjustable ratio and no batch processing function. Dedicated desktop compression software needs installation, occupies device space and is not portable. Some tools will upload images secretly and bring privacy risks.
