How to compress an image to 100KB
Upload a JPG, PNG, WebP, or BMP image, keep the target at 100KB, and download the optimized file. The compressor reduces quality and, when needed, gently resizes the image until it fits under your selected file size.
This tool is useful for visa forms, exam portals, job applications, school forms, ecommerce listings, and websites that reject large image uploads. Because processing happens in your browser, the image is not sent to a server.
Frequently asked questions
Can I compress an image to an exact KB size?
The compressor works toward your selected file size and downloads a file under the limit when the browser can produce one. Very small targets may require WebP output or smaller dimensions.
Is this image compressor private?
Yes. Compression runs locally in your browser, so the image is not uploaded to a server.
What is the maximum input image size?
The current input limit is 25MB to keep compression stable on phones, tablets, and laptops.
