Compress Image
Reduce image size while maintaining visual quality. Supports JPG, PNG and WebP.
About this tool
Compress Image reduces the file size of JPG, PNG, and WebP photos without sacrificing perceptible quality. You control the compression level through a quality slider, letting you balance sharpness and final file size according to your needs.
To use it, select one or several images from your device — the tool accepts files individually or in batch mode. Adjust the quality level (default 70%, which gives a good size-to-sharpness ratio for most photos) and click Compress. The result appears side by side with the original, showing the savings in KB or MB. You can download each image separately or, in batch mode, grab all of them at once as a ZIP file.
Common use cases: reducing photos before sending via email or messaging apps, optimizing images for a website or portfolio without server-side reprocessing, preparing product thumbnails for e-commerce, and shrinking screenshots or presentation images before sharing.
All processing happens directly in your browser using the browser-image-compression library. No files are uploaded to any server. No account, login, or installation required.
