Fine detail and gradients
Zoom into text, edges, gradients and texture. Stronger compression can show up in these areas before it is obvious elsewhere.
Compress HEIF Files Online
Reduce HEIF image size for websites, sharing and storage. Photographic detail, export quality and existing compression all affect how much smaller the file can become. Pick the level that suits the file, then download the reduced version from the same page.

HOW IT WORKS
Compress HEIF files in a few steps
The entire job stays on one page from upload to download.
01
Upload HEIF files
Drag and drop your HEIF files or choose them from your device. Add one file or a batch.
02
Choose compression
Select the compression level that fits the file and how you plan to use it.
03
Download the result
Download the smaller HEIF file and compare it with the original before deleting your source.
HEIF Compression
What affects HEIF file size?
The format is only one part of the answer. The image content and encoding choices matter too.
HEIF files can vary widely even when two images look similar
High efficiency image file container used for compact modern photos and image sequences. Dimensions, color depth, transparency, metadata and previous optimization can all change the final size.
Compression may reorganize the file, remove unnecessary data or use a more compact encoding. If the file is already optimized, expect a smaller reduction.
Image Quality
What should you check after compressing HEIF?
Compare the result with the source before replacing the original.
Transparency and color
Check the color behaviour, transparency or bit depth that matters to the file. Some workflows depend on details that a quick thumbnail will not reveal.
Troubleshooting
Why did my HEIF file barely get smaller?
A small reduction can be completely normal.
01
The file is already optimized
Some applications already write compact files, leaving little unnecessary data for a second pass to remove.
02
The image contains a lot of detail
Texture, gradients and many unique colors can make the image harder to shrink.
03
The pixel dimensions are large
Compression reduces file weight, but it does not automatically make the image narrower or shorter.
04
The format may not be ideal for delivery
If keeping HEIF is not essential, a modern delivery format such as JPEG may be worth comparing.
USE CASES
When a smaller HEIF file is useful
Practical reasons to reduce HEIF file size without losing sight of what the format is used for.
Compress HEIF images before sharing
Reduce HEIF file size before sending images through email, chat or a shared folder.
Reduce HEIF storage in image libraries
Large collections can benefit from smaller files when the format needs to be kept for compatibility or archival reasons.
Make HEIF assets easier to move between systems
Compression can reduce transfer time when a project includes many images or remote collaborators.
Compress multiple HEIF files in one session
Process a batch of HEIF files with the same compression level before download or archive handoff.
Choose The Right Format
Compress HEIF or convert it to JPEG?
Keep the current format when compatibility or workflow requirements make it necessary.
Keep HEIF
Compress the file when you still need HEIF after optimization and want the smallest practical version of the same format.
Try JPEG
Compare a JPEG copy when smaller delivery size or broader modern support matters more than keeping HEIF.
