How much can I compress my images?

Compression depends on the image content. Typically, you can reduce file sizes by 50-90% while maintaining acceptable visual quality.

What image formats are supported?

We support PNG, JPG/JPEG, and WebP formats. Files up to 50MB can be compressed.

How does target size compression work?

The tool uses binary search across quality levels to find the highest quality that fits within your target size. It automatically adjusts compression parameters in multiple passes.

What is the difference between lossy and lossless compression?

Lossy compression (JPEG, WebP) reduces file size by removing some image data, which may slightly reduce quality. Lossless compression (PNG) reduces size without quality loss. Our tool uses smart quality search to find the best balance.

Does Image Compressor upload my files to a server?

No. All processing happens entirely in your browser. Your files never leave your device, ensuring complete privacy and security.

Can I compress multiple images at once?

Currently, the Image Compressor processes one image at a time for precise target file size control. For batch operations, try our Batch Photo Editor.
