Why compress images?
Large images slow down websites, consume storage, and hurt SEO. Compressing images reduces file size while keeping visuals sharp. Our bulk compressor lets you process many images at once with adjustable quality, optional resizing of oversized images, and support for JPEG, PNG, and WebP.
How to use the Compressor
- Drag and drop images into the upload zone or click to browse.
- Choose output format (JPEG, PNG, or WebP).
- Adjust the quality slider—lower values mean smaller files and slightly lower quality.
- Optional: enable "Resize large images" to cap width (e.g., 1920px).
- Click "Compress" and wait for processing to complete.
- Compare before/after sizes and download all results as a ZIP.
All processing happens in your browser. Your images are never uploaded to a server.
