What Image Optimizer does
Resize, compress, crop, and convert JPG, PNG, and WebP images right in your browser — nothing is uploaded to a server. Resize by exact dimensions or percentage, crop with freeform or social-media aspect presets, and compress down to a target file size in kilobytes. Process one image or a whole batch at once, then download everything together as a ZIP. No account required, and exports never carry a watermark.
Designed for quick, mobile-friendly use without the complexity of large business software.
