Make a HEIC file smaller without changing formats
Use the HEIC compressor when you want a smaller HEIC file, not a JPG, PNG, or PDF copy. Compression trades some image quality for a smaller file.
How to compress HEIC
Choose the HEIC image, select the compression quality you want, and start the compression. The result stays in HEIC format.
If file size matters, try a balanced setting first and compare the result before using a more aggressive setting.
File size and image quality
There is no single percentage that every HEIC file will shrink by. The result depends on the image itself and the quality setting you choose.
Judge the compressed file by both size and appearance. A smaller file is only useful if it still looks good enough for how you plan to use it.
Processing and metadata
The HEIC compressor uses Cloud processing, so the file is uploaded to Morphio. Uploaded images are deleted by default after one day.
Supported metadata is kept when the compression path can preserve it, but HEIC-specific information may not always survive every processing step.
Check the compressed file
Compare the result with the original at the size you care about. Check important detail, orientation, metadata you need, and whether the new file is small enough to solve the original problem.
To check the picture without changing it, open the HEIC viewer.
Compressing vs. converting
Compress HEIC when you want to keep the HEIC format but reduce file size. Convert to JPG, PNG, WebP, or PDF when the problem is format compatibility rather than size.
A simple rule
Reduce a HEIC file when the format already works for you and the main problem is size. If an app or website does not accept HEIC at all, convert the file instead.

Frequently asked questions
Common questions about making HEIC files smaller.
Yes. The compressor is for reducing HEIC file size while keeping HEIC output.
It depends on the image and the quality setting. Compare the finished size and image quality rather than expecting a fixed percentage.
Yes. The HEIC compressor uses Cloud processing, and uploaded images are deleted by default after one day.
Compress when HEIC is already compatible and you only need a smaller file. Convert when another format is required.
