Frequently Asked Questions

Can I convert iPhone HEIC photos to JPG or PNG on Windows/Android/Mac?

Yes! ToolZappy includes native client-side HEIC decoding that converts iPhone photos (.heic / .heif) to standard JPG or PNG files without uploading them to any cloud service.

Why should I convert my website images to WebP?

Google recommends WebP because it provides 25%–35% smaller file sizes than standard JPG and PNG at identical visual quality, boosting site speed and Core Web Vitals scores.

Can I convert a transparent PNG into a JPG?

Yes. When converting a transparent PNG to JPG, ToolZappy automatically renders a clean, crisp solid white background behind your transparent areas.

Are my uploaded photos or graphics sent to a remote server?

No. All format decoding and encoding execute 100% inside your browser using HTML5 Canvas. Your files are never uploaded or stored anywhere.
