How to compress image to 100kb in online

Compress or Resize image to 10kb


When it comes to sharing images online, it's important to keep the file size as small as possible without compromising on image quality. This is because large file sizes take longer to upload and download, and can also take up a lot of storage space. In this article, we'll discuss how to compress an image to 100kb without sacrificing image quality.

Step 1: Resize the Image

The first step in reducing the file size of an image is to resize it. This can be done using any image editing software, such as Photoshop or online compressor website. The idea is to reduce the dimensions of the image while maintaining the aspect ratio. For example, if the original image is 2000 x 1500 pixels, you can resize it to 1200 x 900 pixels, which is roughly 30% smaller. This will significantly reduce the file size of the image without any noticeable loss in quality.

Step 2: Reduce the Image Quality

The next step is to reduce the image quality. This means lowering the image's resolution, which is measured in dots per inch (DPI) or pixels per inch (PPI). For online images, a resolution of 72 DPI is sufficient. If the original image has a higher resolution, you can reduce it to 72 DPI without any noticeable loss in quality.

Step 3: Adjust the Compression Level

The final step is to adjust the compression level. This can be done using the Save for Web or Export options in your image editing software. The compression level determines how much data is discarded from the image to reduce its file size. The higher the compression level, the smaller the file size, but also the lower the image quality.

To compress an image to 100kb, you may need to experiment with the compression level to find the right balance between file size and image quality. Generally, a compression level of 100-70% is sufficient to achieve a file size of 100kb without compromising on image quality.


Compress an image to 100kb can be done by resizing the image, reducing the image quality, and adjusting the compression level. By following these steps, you can significantly reduce the file size of an image without sacrificing its quality. Remember to always save a copy of the original image before compressing it, so you can revert back to it if necessary.
