About

ConvertArena is a growing set of free, browser-based file conversion tools. It started with HEIC to JPG, PNG, and PDF, and more formats are being added from there.

ConvertArena's HEIC tools convert HEIC and HEIF photos (the format iPhones save photos in by default) into JPG, PNG, or PDF. They exist because HEIC files are efficient for storage but frustrating for compatibility, and most existing converters require uploading your personal photos to an unknown server just to change a file extension.

Every conversion on this site runs locally, inside your browser, using WebAssembly and a background worker thread. No file is ever uploaded, stored, or seen by anyone but you. There's no server in the conversion path to send it to in the first place.

Every tool on this site runs on your device instead of uploading to a server. That's not a technical detail, it's the actual privacy guarantee: a server that receives your file could log it, cache it, or get breached, no matter how careful the people running it are. Skipping the upload step entirely means there's nothing to log, cache, or breach in the first place.

ConvertArena is meant to grow past HEIC over time. More tools, covering more file types, are being added on a regular basis, with the goal of being one place worth bookmarking instead of a different site for every file you need to convert.

ConvertArena is built and maintained by Sudhan Richardson. If you run into a bug or have a feature request, see the contact page.
