Image compression guide
Compress images without complicated software
Large image files can take longer to upload, download, share, and display on websites. Image compression reduces file size by changing image encoding and, when enabled, reducing image dimensions.
Compress multiple images
Add multiple images to the queue, process them together, and download the results individually or as a ZIP file.
Process images in your browser
Compression happens in the browser on your device, without requiring the selected images to be sent to a compression server.

When should you compress images?
Compressing images can be useful before uploading photos to websites, sending files by email, sharing images through messaging apps, or adding media to documents.
For websites, reducing unnecessary image file size can also help reduce the amount of data a browser needs to download. Choosing an appropriate image format and dimensions is often as important as the compression quality.
If an image is much larger than the dimensions where it will actually be displayed, resizing it before download can reduce its file size further.
Frequently asked questions
Is this image compressor free?

Does the tool upload my images?
The compression process runs in your browser using the selected local files. The tool does not need to upload those files to a server to perform the compression.
