Why reduce image size?
Reducing image size is useful when images are too heavy for websites, forms, emails or storage. Smaller images are easier to upload, faster to send and better suited for online publishing.
For websites, reducing image size can help improve loading speed and create a smoother user experience. For email and documents, smaller images help keep files manageable. For online forms and platforms, reducing image size can help meet upload limits.
File size vs image dimensions
Image file size
Image file size refers to how much storage space the image uses, usually measured in KB or MB. Compressing an image can reduce file size while keeping the same width and height.
Image dimensions
Image dimensions refer to the width and height of the image, usually measured in pixels. Resizing an image can reduce dimensions and may also reduce the final file size.
If your goal is to upload a file under a size limit, compression may be enough. If your image is extremely large in pixels, resizing the image can also help reduce the file size.
Common image formats
JPG
JPG is commonly used for photos and general web images. It usually compresses well and can create smaller files.
PNG
PNG is often used for screenshots, logos, icons and transparent graphics. PNG files can be larger, especially when they contain detailed images or many colors.
WebP
WebP is a modern image format designed for the web. It can often create smaller files while keeping good visual quality.
Choosing the right format can help reduce image size without making the image look unnecessarily degraded.
Common use cases
