Common Questions About Image Compression

Is There a Size Limit for Image Compression?

Since compression is done locally and affected by browser memory, it is recommended that a single image does not exceed 50MB.

Why Doesn’t the Image Size Change After Compression?

This may be because lossless compression (such as PNG, GIF, WebP lossless mode) is used or the compression setting is too low, which fails to effectively reduce the file size. You can try using lossy compression (such as JPEG format) and adjust the compression quality settings to better reduce the file size.

What to Do If Image Compression Fails?

This tool supports operation in mainstream browsers and is compatible with mobile phones and tablets. It is recommended to use Chrome or other Chromium-based browsers.
