Image Resizer vs Image Compressor
Resizing changes the dimensions of an image. For example, 4000 × 3000 becomes 1200 × 900. Compression changes the file data so the image can be stored as a smaller file, often without a major visible difference.
Use the Image Resizer when a specific width and height is required. Use the Image Compressor when the goal is to reduce file size while keeping the current dimensions.
Common Questions
Can I resize to a specific dimension?
Yes. Enter width and height in pixels, or choose a percentage scale to resize the image quickly.
Does the tool preserve aspect ratio?
Yes. The lock-ratio option keeps proportions consistent when you change width or height.
Is the resize processing safe?
Yes. The image is processed in your browser, which means it is not uploaded to a remote server for resizing.
