What Is This Tool?
This tool lets you convert and archive HEIF image files into 7Z archive format. It combines the efficient image container capabilities of HEIF with the high compression and encryption features of 7Z, enabling secure and compact distribution or backup of your photos and image sequences.
How to Use This Tool?
-
Upload your HEIF files or folders containing HEIF images to the tool
-
Choose 7Z as your output archive format
-
Optionally enable encryption with a password for added security
-
Select multi-volume archive option if you need to create split archives
-
Click convert to generate a compressed 7Z archive of your HEIF files
Key Features
-
Supports archiving one or multiple HEIF images, including sequences and metadata
-
Uses 7Z format with powerful LZMA/LZMA2 compression for reduced storage size
-
Offers AES-256 encryption for secure file protection in archives
-
Supports creating multi-volume (split) archives for size-limited transfers
-
Preserves directory structures and embedded metadata during compression
Examples
-
A photographer compressing a month of HEIF photos into a single AES-encrypted 7Z archive for offsite storage
-
A developer bundling HEIF image sequences into multi-volume 7Z archives to meet file size restrictions for transfer
-
Archiving a collection of burst-mode HEIF images with preserved metadata in one compact 7Z file
Common Use Cases
-
Creating encrypted backups of HEIF photo libraries to save disk space and maintain metadata
-
Bundling multiple HEIF images or sequences into a single archive for simplified sharing or storage
-
Distributing HEIF assets such as Live Photos with high compression and optional password protection
-
Producing split archives for transferring large HEIF collections across media with size constraints
Tips & Best Practices
-
Ensure recipients have compatible tools to extract 7Z archives and support HEIF decoding
-
Use AES-256 encryption to protect sensitive image collections during storage or transfer
-
Consider multi-volume archives to handle size limits on transfer media or services
-
Be aware that extracting individual files from solid-compressed 7Z archives may require more processing time
-
Maintain updated software to support full HEIF features and avoid data loss when re-editing after extraction
Limitations
-
Viewing or editing extracted HEIF files requires tools with HEIF and specific codec support
-
HEIF files typically use HEVC codecs subject to patent and licensing restrictions affecting distribution
-
7Z archives are not natively supported by all operating systems; third-party software may be needed for extraction
-
Solid compression increases effort to extract or modify individual files within the archive
-
Compression and decompression can be resource intensive on systems with limited CPU or memory
-
Some downstream applications may not fully support HEIF auxiliary images and metadata, risking data loss
Frequently Asked Questions
-
Can I view HEIF images directly inside the 7Z archive?
-
No, HEIF images must be extracted from the 7Z archive and viewed with compatible software that supports the HEIF format and its codecs.
-
Is AES-256 encryption available when archiving HEIF files to 7Z?
-
Yes, you can apply strong AES-256 encryption to the 7Z archive to secure your HEIF files during storage or transfer.
-
Why might I want to create multi-volume 7Z archives for HEIF files?
-
Multi-volume archives help split large HEIF collections into smaller parts, useful for transfer over media or networks with size limits.
Key Terminology
-
HEIF
-
A modern image container format that stores images and sequences with high compression efficiency and supports auxiliary data like depth and alpha channels.
-
7Z
-
An open archive format using high compression algorithms like LZMA/LZMA2, supporting encryption, multi-volume archives, and large file storage.
-
AES-256 Encryption
-
A strong encryption standard used to securely protect the contents of archives against unauthorized access.
