HEIC Photo Locker lets you password protect multiple HEIC photos at once. Choose up to 60 HEIC or HEIF files, set one password, and download a single encrypted ZIP. Everything happens inside your browser using AES-256 encryption, so your photos are never uploaded and we never see your password. No signup, no software, no cost.
Important: there is no password recovery. Save your password safely and keep your original photos until you have unlocked the ZIP once with the HEIC Photo Unlocker.

What Is HEIC Photo Locker?
HEIC Photo Locker is a free online tool that encrypts HEIC and HEIF photos with a password you choose. It uses AES-256-GCM encryption, runs entirely in your web browser, and returns a ZIP file containing your locked photos. Because the work happens on your device, your pictures never travel to a server. Only someone with your password can bring the original photos back.
Lock Multiple HEIC Photos at Once
You can lock up to 60 HEIC photos (400 MB in total) in one batch. All photos in the batch use the same password and are saved together in a single ZIP, so you enter your password only once. If you have more photos, lock them in several batches.
How to Lock HEIC Photos
- Choose your HEIC photos. Tap the upload area or drag and drop your files. The tool checks each file’s real format and accepts genuine HEIC and HEIF photos only.
- Set a password. Use at least 6 characters (12 or more is recommended) and confirm it.
- Click Lock photos & download ZIP. Each photo is encrypted, then decrypted again as a safety check before anything is saved.
- Save your ZIP and your password. Store them in different places.
- Test before deleting originals. Unlock the ZIP once with the HEIC Photo Unlocker to confirm it works.
Where to Find Your HEIC Files
- iPhone or iPad: in Photos, select your pictures, tap Share, then Save to Files.
- Mac: in Photos, choose File, Export, Export Unmodified Original.
- Windows or Android: select the .heic or .heif files saved by your camera or gallery app.
Why You Can Trust the Result
- Built-in safety check: every photo is decrypted again and compared with the original before the ZIP is created.
- Original quality: photos are not resized, recompressed or converted.
- Password cleared: the password fields are emptied once locking finishes.

Why Lock HEIC Photos?
Phone photos can carry more than the picture. Metadata inside the file can include the date, the camera model and sometimes the GPS location. Locking encrypts the whole file, so the image and its metadata stay unreadable without your password. This is useful before you upload photos to cloud storage, send them by email, copy them to a USB drive, or share them with a client.
Frequently Asked Questions
Can you password protect a HEIC file?
Yes. HEIC files have no built-in password option, so you protect them by encrypting them. HEIC Photo Locker encrypts your HEIC photos with AES-256-GCM using your password and packs them into a ZIP. Without the password, the photos cannot be opened.
Can I lock multiple HEIC photos at once?
Yes. You can lock up to 60 HEIC photos (400 MB in total) in one batch. All photos share one password and are saved together in one ZIP. For more photos, lock them in several batches.
Is HEIC Photo Locker free?
Yes. It is completely free, with no signup, no watermark and no email required. You can lock as many batches as you like, each up to 60 photos and 400 MB.
Are my photos uploaded to a server?
No. Locking happens in your browser using the Web Crypto feature built into modern browsers. Your photos and password stay on your device and are not sent to our server, so we cannot see, recover or share your files.
Does it only work for iPhone photos?
No. HEIC is used by iPhone and iPad, but also by some Android phones, cameras, and Windows and Mac computers. If you have a .heic or .heif file from any device, you can lock it here.
Will locking reduce quality or change the format?
No. The tool does not resize, recompress or convert anything. It encrypts the original HEIC file as it is and decrypts it again as a check before saving. After unlocking, you get back the identical file.
What if I forget my password?
Your photos cannot be recovered. The password is never stored or sent anywhere, and AES-256 has no backdoor or reset option. Save it in a password manager and keep your originals until you have confirmed you can unlock the ZIP.
Can I open the ZIP with a password in 7-Zip or WinRAR?
No. It is not a standard password-protected ZIP. It is a normal ZIP container that holds encrypted files and a manifest. You can open the container, but the photos inside stay unreadable until you unlock them with the HEIC Photo Unlocker.
Does locking remove location data?
No. Locking encrypts the whole file, including location and camera metadata, but does not delete it. After unlocking, the photo returns exactly as it was. To remove metadata, use an EXIF remover before locking.
How do I unlock my photos later?
Open the HEIC Photo Unlocker, choose the locked ZIP, enter your password and save your original photos. It works only with ZIP files created by this Locker, and it unlocks all photos in the ZIP at once.
How do I unlock my photos later?
Open the HEIC Photo Unlocker, choose the locked ZIP, enter your password and save your original photos. It works only with ZIP files created by this Locker, and it unlocks all photos in the ZIP at once.
Can I lock JPG, PNG or other files?
No. This tool is built only for HEIC and HEIF photos. It checks each file’s actual signature, not just its extension, and rejects other formats.
Does it work on phones and tablets?
Yes. It works in modern mobile browsers over HTTPS. Encryption uses your device’s processing power, so on older phones lock fewer photos at a time if you see an error or slow progress.
Disclaimer
HEIC Photo Locker is provided free and “as is”, without warranties of any kind. Encryption happens in your browser and your photos are not uploaded, so we cannot access, recover or reset your password or your files. If you lose your password, your locked photos cannot be restored. Keep your original photos until you have unlocked the ZIP and checked the results. The strength of the protection depends on the password you choose, and no tool can protect files on a device that has malware or untrusted browser extensions.
The ZIP file name and the file names, file sizes, fingerprints and number of photos listed in its manifest are not encrypted. Results can be affected by unsupported browsers or low device memory, so lock fewer photos at a time if you see an error.
