HEIC to JPG
Convert HEIC images to JPG. HEIC is built for iPhone camera rolls, and very little outside Apple's ecosystem; JPEG for photographs, and it is the one raster format every piece of software opens. JPG has no alpha channel, so transparency is flattened onto a solid background. Both formats are lossy, so this is a re-encode and a little detail goes each time. Start from the best source you have rather than chaining conversions. Runs on your own Vistalyth Tools instance. Files never reach a third party.
Features
- Pick the background colour that transparency is flattened onto
- Batch conversion across a folder of HEIC files
- Metadata and colour profile carried over wherever JPG can hold them
- Your HEIC files are processed on your own server and never uploaded anywhere
What you can do
- Open iPhone photos in software that has never heard of HEIC
- Batch a folder of HEIC files into JPG in one pass
- Satisfy an upload form or pipeline that takes JPG and rejects HEIC
Self-hosted. Your files never leave your network.
Vistalyth Tools runs entirely on your own infrastructure. Files processed with HEIC to JPG are never uploaded to third-party servers. Deploy a single Docker container and process files with full privacy, no watermarks, and no usage limits. Open source under AGPL-3.0.
Frequently asked questions
- Will converting HEIC to JPG lose quality?
- The visible pixels survive intact; it is the transparency that does not. Composite against the background you will actually display on, or the edges will fringe.
- What happens to transparent areas?
- They are composited onto a background colour you choose, white by default. There is no way around it: JPG has nowhere to store an alpha channel.
- Can I go back to HEIC afterwards?
- You can convert back, but you will not recover the original. HEIC discarded detail when it was first written, and JPG cannot invent it. Keep the source file if you might need it.
