Frequently Asked Questions
Does compressing an image reduce its dimensions? ▾
Not by default. Compression primarily reduces the file size (Megabytes) by removing unnecessary metadata and optimizing pixel data. The physical dimensions (width and height) remain unchanged unless you specifically choose to resize the image using our Image Resizer tool.
What is the WebP image format? ▾
WebP is a modern image format created by Google that provides superior compression for images on the web. WebP images are typically 25-34% smaller than comparable JPEG images while retaining the same visual quality. Our tool allows you to convert JPG and PNG files directly to WebP.
Is there a limit to how many images I can compress? ▾
No! ImageCrush allows for unlimited uses. Since the processing relies on your own device rather than our servers, there are no quotas, no sign-ups, and no daily limits. Upload files up to 20MB completely free.
