Is Image Compressor safe?

Absolutely safe. All data processing happens locally in your browser. Nothing is uploaded to any server, ensuring your privacy is fully protected.

Do I need to install software to use Image Compressor?

No installation needed. All tools run in your browser - just open the page and start using them immediately.

How does image compression work?

Image compression reduces file size by removing unnecessary data. Lossless compression preserves all image data, while lossy compression removes some data that's less noticeable to the human eye. This tool primarily uses lossy compression with adjustable quality.

Will compression reduce image quality?

Lossy compression does reduce quality, but at moderate settings (70-85% quality), the difference is barely noticeable to the human eye while achieving significant file size reduction. Lossless compression preserves quality but achieves smaller reductions.

What image formats are supported?

This tool supports PNG, JPEG (JPG), and WebP formats — the most common image formats used on the web. Output format matches the input format by default.

Is there a file size limit?

Since all processing happens in your browser, there's no server-side limit. However, very large images (50MB+) may cause your browser to slow down. For best results, keep individual images under 20MB.

Are my images uploaded to a server?

No. All image processing happens entirely in your browser using Canvas API and Web Workers. Your images are never uploaded to any server, stored, or logged.
