No. Everything runs in your browser - your file never leaves your device. How this is verifiable
HEIC is the default photo format on modern iPhones. It saves space but is not opened directly by Windows, many websites and older software. JPG solves that compatibility problem and is ideal for photos because the file stays small.
This tool decodes HEIC entirely locally in your browser (libheif) and exports JPG. Your photos are not uploaded - the conversion works even in airplane mode.
HEIC stores its images with the HEVC codec (H.265) inside the HEIF container - the same technology used in modern video. That explains the small files, but also the compatibility gap: licensing and software reasons keep many programs away from HEVC. JPG has been the common denominator for photos since the 1990s and runs on every device, printer and web service - which is exactly why converting helps when you want to share, upload or print an image.

Limitations: Very large HEIC batches can use a lot of memory on older mobiles. Live Photos are converted as a still image. JPG stores no transparency.
No. HEIC is decoded entirely locally in the browser.
Because they are in HEIC format. After converting to JPG it works everywhere.
Only if you need transparency or lossless edges - then use HEIC to PNG.
Yes, with ZIP download.
Usually yes. HEIC uses HEVC compression and often stores a photo at comparable quality only about half the size of JPG. In return, JPG is readable on every device, printer and web service, where HEIC often fails outside the Apple ecosystem. Use the quality slider to set the JPG size; 80 to 90 percent is a good balance of sharpness and file size.
HEIC and JPG are both lossy, so converting is a re-encode with minimal loss that is invisible to the eye at a high setting. If you need the maximum for an archive, keep the HEIC original too; for sharing, uploading and printing, JPG is the more practical choice.
