Convert HEIC to PNG
The efficient photo format iPhones shoot by default: smaller than JPG at similar quality. Lolly reads HEIC/HEIF photos even on browsers that can't open them, using a bundled decoder, so an iPhone photo just works as an image. It's import-only, and it carries no Content Credential.
The go-to lossless image format, with real transparency, so nothing is thrown away and edges over a background stay clean. Great for logos, screenshots and artwork. Lolly tags it with an sRGB profile, can boost it to genuine HDR brightness on capable screens, and embeds provenance and Content Credentials.
Most tools like this are upload sites: your file goes to their server, and ads pay the bill. Lolly runs on your device, so your file stays with you.

- Lossless quality
- HDR bright colour
- Content Credentials (C2PA)
What carries over: EXIF, XMP - The converter moves the description, author, copyright and capture date into the new file. Location stays behind unless you turn it on, and a Content Credential cannot be copied: it is bound to the original bytes.
Content Credentials survive this format
