Review your batch
Ready to convert
Choose or drag HEIC/HEIF files above. They will appear here before conversion so you can review the batch, remove anything you do not want, and check the estimated output size.
Conversion uses your device's memory. For large libraries, convert in smaller batches (around 20–30 photos at a time) instead of all at once.
How is this private?
Most "online converters" upload your photos to their servers. This one doesn't. A HEIC decoder compiled to WebAssembly runs inside your browser tab, so your photos stay on your device from start to finish.
-
You pick photos
Files are read locally by your browser. No network request is made.
-
Your device converts them
WebAssembly decodes the HEIC and re-encodes it as JPG or PNG, right in this tab.
-
You download the results
Saved straight from memory to your downloads. Close the tab and everything is gone.
Don't take our word for it: open your browser's developer tools (Network tab) while converting and you'll see zero uploads. It even works in airplane mode.
Private by design
Your photos can't leak from a server that never receives them. Nothing to delete, nothing to trust.
Faster than uploading
No upload or download queues. Conversion starts instantly at your device's full speed.
Works offline
Once the page has loaded, you can disconnect entirely and keep converting.
FAQ
Why are my iPhone photos HEIC?
Apple uses HEIC because it keeps image quality high while reducing file size compared with older formats. It saves storage space on your phone and in backups.
How do I convert HEIC to JPG on Windows 11?
Open this page in your browser, drop your HEIC files, and download the converted JPG files. It works on Windows 11 without uploading your images anywhere.
Does converting HEIC to JPG lose quality?
JPG is a lossy format, so some detail can be lost. You can increase the quality slider for better visual results, but files will usually be larger.
Can I use this for work files or sensitive documents?
Yes. Many workplaces prohibit uploading company files to third-party websites, and for good reason: once a file reaches someone else's server, it's out of your control. This tool never uploads anything, so scanned IDs, contracts, medical records, or work photos stay on your machine the whole time. Using it is no different from converting the file with software installed on your own computer, so there's no data-handling policy to worry about breaking.
Is it safe to convert HEIC files online?
With a typical online converter, your photos are uploaded to someone else's server, and from that moment you're trusting them completely. You have to trust that they actually delete your files instead of quietly retaining them, that they won't use your images to train AI models, that their storage won't be breached, and that nothing intercepts the transfer along the way. Their privacy policy can also change at any time, long after your photos have already left your hands.
This tool removes that entire question. Your photos are never transmitted anywhere. Conversion happens inside your own browser, on your own device. There is no server copy to delete, no dataset to end up in, and nothing to intercept. Whether it's family photos, documents, or anything you'd simply rather keep to yourself, the safest upload is the one that never happens.
