About HEIF Converter

A free, browser-based tool for converting Apple's HEIC and HEIF photos into formats you can actually use — without ever uploading a single file.

Our promise: Your photos never leave your device. We do not host, store, upload, or transmit any image you convert. Every conversion happens entirely inside your browser, using WebAssembly. There is no server-side processing because there does not need to be one.

Why we built this

If you've ever tried to share an iPhone photo with a Windows user, upload one to an older website, or attach one to an email that didn't render, you've run into the HEIC problem. Apple has used HEIC as the default photo format on iPhones and iPads since iOS 11 (2017) because it produces smaller files at the same quality as JPEG. Apple's ecosystem reads HEIC natively. Almost nothing else does.

The result is that millions of people end up looking for a way to convert HEIC photos every day. Most of them land on websites that demand they upload their photos to a server — frequently their most personal photos, of family, kids, identity documents, medical records, or screenshots of bank apps. Those servers are run by companies the user has never heard of, often in jurisdictions they cannot identify, with privacy policies they have not read.

HEIF Converter exists to make that trade-off unnecessary. The same conversion can be done entirely inside your web browser, using technology that's been built into every modern browser for years. We just wired it together and put a clean interface on top.

How it actually works (the technical part)

When you drop a HEIC file into HEIF Converter, here is what happens:

No network request is ever made with your image. You can verify this yourself: open your browser's Developer Tools, switch to the Network tab, drop a file into the converter, and watch — nothing is uploaded.

Who runs HEIF Converter

HEIF Converter is built and maintained by a small independent team focused on building privacy-respecting web tools. We do not represent any larger company, do not sell your data, and do not have a venture-capital growth target to hit.

The site is hosted on Vercel from a static codebase. The conversion code is open-source upstream (libheif, heic2any, jsPDF, JSZip), and we publish the site's source structure transparently — what you see in the page is the entire application.

How we keep this free

HEIF Converter is supported by display advertising (Google AdSense). The ads are deliberately limited to a small number of clearly-marked slots — we do not auto-load aggressive ad networks, do not run pop-ups, and do not run sticky bottom-bar ads on mobile. Our policy is that the tool comes first; the ads are how we keep it free, not the other way around.

If you want to know exactly which cookies our ad and analytics partners use, our Cookie Policy spells them out in detail.

What we believe

Privacy by architecture

The most reliable way to protect user data is to never collect it. We process images in the browser because we don't need a server to do it — so we don't run one.

No artificial limits

No "free tier" trick where you hit a paywall after three files. Convert one file. Convert two thousand. The tool works the same.

No account, ever

You shouldn't need to sign up, log in, or hand over an email to do something as ordinary as converting a photo.

Standards over lock-in

JPG, PNG, WebP, and PDF are open formats that every device understands. The output is yours, immediately, with no DRM and no expiry.

If you have a specific need or run into a file that doesn't convert, tell us. The site's roadmap is driven by what users actually need.
