Image Size, File Size and Compression: What Is the Difference?
Image size can mean two different things: the file size, measured in KB or MB, and the image dimensions, measured in pixels. Reducing file size makes the image lighter for upload, email, websites or social media. Resizing changes the width and height of the image. Compression reduces the file weight by optimizing the image data, usually while keeping the same dimensions. Use this tool when you want a smaller image file.
Does Reducing Image Size Change Dimensions?
Not always. Reducing image size can mean compressing the file, resizing the image dimensions or using both methods. If you want to keep the same width and height, use compression. If you need a specific pixel size, use a resize image tool.
Reduce Image Size for Uploads
Many websites, forms and online services limit the maximum image file size. This tool helps you make images smaller before uploading them, without installing software or sending your files to an external server.
How to Keep Good Quality When Reducing Image Size
To keep good quality, avoid using the strongest compression level unless you need the smallest possible file. A balanced setting is usually enough for websites, emails and social media. If your image contains text, logos or small details, use lighter compression or reduce the dimensions carefully.
Supported Image Formats
This image size reducer supports common formats such as JPG, PNG and WebP. JPG is often best for photos, PNG is useful for graphics and transparent images, and WebP is a modern format designed to create smaller images for the web.
Is Image Size Reduction Safe?
Yes. Your images are processed locally in your browser and stay on your device. They are not uploaded to external servers, which helps protect your privacy.
