FAQ

Frequently Asked Questions

Are my photos uploaded to any servers?

Never. Every single mathematical compression, format conversion, and PDF encryption algorithm runs solely on your smartphone's processor using an isolated background isolate. You can safely compress photos with Wi-Fi and mobile data completely disabled.

Why won't Apple iPhone HEIC photos open on Windows?

Apple uses the proprietary HEIC format to save space, but most Windows PCs, older smartphones, and web portals lack native support. Vanza Convert & Compress effortlessly converts bulk batches of HEIC files into universal JPEG or PNG formats in seconds.

Will my images look blurry after compression?

No. Our smart compression algorithms strip out invisible redundant metadata and optimize pixel encoding while preserving razor-sharp edges and color fidelity. You also get a real-time file size forecast before initiating compression.
