Compression instructions below
You can reduce heif file size by setting a specific desired output file size or reduce by percentage.
-
Enter the desired HEIF file size in kilobytes and then click "Next".
-
To reduce HEIF by percentage, click the "By Percentage" tab and enter your desired percentage reduction. E.g. 30 for 30% file size reduction and click "Next".
You will be redirect to the correct file compression page. The page contains further instructions for reducing HEIF file size.
At ezyZip, we offer an advanced compression feature that allows you to reduce the size of your HEIF files either by setting a specific target file size or by selecting a percentage reduction. This functionality is perfect for tailoring HEIF files to meet various requirements or limitations. Whether you need to comply with size constraints for uploads and emails, or simply want to save disk space, you can easily customize the compression to fit your needs.

Why client-side HEIF image compression keeps your photos private
Every pixel of your HEIF images is processed within your browser's WebAssembly sandbox when using ezyZip. Here is why local image compression is technically superior:
- Desktop-Class EngineThe Emscripten-compiled image processing engine runs the same class of algorithms used by professional desktop tools — including advanced quantization, chroma subsampling, and progressive encoding — entirely within isolated browser memory.
- Multiple Compression ModesChoose between quality-based, percentage-based, or target-size compression. Each mode uses a different optimization strategy to balance visual quality against file size for your specific needs.
- Efficient Batch DownloadsCompressed outputs are staged through the Origin Private File System for efficient batch downloading. Process and download hundreds of images in a single operation without repeated file-picker interactions.
- Automatic CleanupSession cleanup ensures processed image data does not persist beyond your active browser session. Temporary files in the Origin Private File System are automatically purged when stale, keeping your browser storage clean.
