How to use the Image Compressor
Adjust Compression Quality
Use the quality slider to balance file size reduction against image fidelity. All processing happens locally as you compress image without uploading, keeping your files completely private on your own device.

Private Browser-Based Image Compression
The image compressor runs locally in your browser, so JPEG, PNG, and WebP files do not need to be uploaded to a remote service. This is useful for product photos, screenshots, blog images, and private visual assets.
When to Compress Images Online
Use image compression before publishing web pages, sending email attachments, uploading forms, or sharing images where file size matters. Smaller files can improve page speed and reduce storage without changing the original file on your device.
Supported Formats and Limits
The tool is designed for common web image formats including JPEG, PNG, and WebP. Large files are limited to keep the browser responsive, and compression results depend on image dimensions, format, and quality settings.
