Image Compressor — Reduce Image File Size Online

How It Works

The tool compresses uploaded photos in the browser, scales the resolution downward if it exceeds specifications, and targets the requested file size parameters recursively until optimized.

Example

A typical 4MB JPEG from a phone can easily be compressed to 350KB using the default options while maintaining sharp resolution.

When to use this tool

• Use it when preparing images for website uploads to improve load speed.
• Use it when saving storage space on your device or cloud drive.
• Use it when email or message attachment sizes are restricted.

How to compress images

• Select or drag your image file into the upload zone.
• Adjust the maximum size (MB) and maximum dimensions (px) if needed.
• Click the Compress Image button, then download the resulting file.

Best practices for compression

• For standard blogs or websites, 1MB is a safe maximum target, with 1920px width/height.
• For mobile or social media sharing, you can set target sizes lower to save bandwidth.
• Check the preview sizes before downloading to ensure the compromise works.

Privacy and security benefits

• No server upload means absolute privacy for personal photos or documents.
• Immediate processing without network lag or queues.
• Works completely offline once the page is loaded.
