Frequently Asked Questions

How does auto compression determine the best quality settings?

The tool analyzes basic image characteristics like format and size, then applies standard compression settings that balance visual quality with file size reduction. Different image types receive appropriate compression levels based on their format and intended use.

Is my data secure during compression?

Absolutely. All compression processing happens entirely in your browser using JavaScript. Your images never leave your device or get uploaded to any server. This ensures complete privacy and security, making it safe to process confidential or personal images.

What file formats are supported for auto compression?

We support JPEG, PNG, and WebP formats for both input and output. The tool can automatically detect the best output format based on your input image characteristics, or you can specify your preferred format. WebP typically provides the best compression ratios for modern browsers.

Are there any file size limits?

The only limit is your device's available memory. Since processing happens locally, very large images (100MB+) may take longer to process or could cause memory issues on older devices. For optimal performance, we recommend images under 50MB each.

Can I use this tool for commercial purposes?

Yes, this tool is completely free for both personal and commercial use. There are no usage restrictions, watermarks, or licensing fees. You can use it for client work, business projects, or any commercial application without limitations.

How much file size reduction can I expect?

File size reduction varies significantly based on the original image format, content, and current optimization level. Results can range from modest improvements for already-optimized images to substantial reductions for uncompressed originals.

Does auto compression preserve image metadata?

By default, the tool removes most metadata including EXIF data to reduce file size and protect privacy. If you need to preserve specific metadata for professional workflows, consider using our manual compression tools with metadata preservation options.
