Frequently Asked Questions
Do my files get uploaded to your servers?
No. FileCompressor.online is built with a 100% client-side architecture. When you compress an image, the calculation, encoding, and file generation all occur directly in your browser's local memory. Your files are never sent over the internet to any external server.
Is FileCompressor.online completely free to use?
Yes, FileCompressor.online is completely free. There are no subscriptions, hidden fees, watermarks, or artificial limits on how many times you can compress your photos.
How does it achieve the exact target size without reducing resolution?
Our compression algorithm preserves 100% of the image's original pixel dimensions (width × height) and uses adaptive bisection search to determine the ideal encoding quality parameters to fit exactly within your requested KB target.
Is it safe to compress sensitive personal documents (IDs, passports, tax forms)?
Yes. Because files never leave your computer or phone, it is far safer than conventional cloud-based converters. However, always ensure your own device is secure and free of malware.
