Questions and practical tips
Can every image become much smaller?
No. Files that are already optimized may offer little reduction. This tool avoids replacing a source with a larger compressed output.
Does compression change the image format?
This operation is designed to retain the original format. Use Convert Image when you want to change formats as well.
Processing and file safety
This tool processes files in your browser. Loading the page, libraries or AI models can still require network connections. Keep a copy of your original files and check the downloaded result before deleting them. Large files may require more memory and processing time than your device can provide.
