What is HEIC format and why do I need to convert it?

Absolutely. We prioritize your privacy and security. All conversion happens directly in your browser - your photos never leave your device. We never upload, store, access, or share your personal images. Your files remain completely private.

Can I convert multiple HEIC files at once?

Yes! Our converter supports batch processing. You can select multiple HEIC files and convert them all to individual PDF files simultaneously, saving you time and effort.

Do I need to install any software?

No installation required! Our HEIC to PDF converter works entirely in your web browser. It's compatible with all modern browsers on Windows, Mac, iOS, and Android devices.
