Compress Image to a Specific KB Size

You can also use the tool as a compress JPG online, compress PNG online or compress WebP online solution depending on the selected output format.

How to Reduce Image Size in KB

If an image is too large for an upload form, you can reduce its file size by lowering the compression quality or selecting a target size. The best setting depends on the original dimensions, image format, details and colors in the image.

For example, if a website asks you to upload a photo under 100KB, select 100KB as the target. If the website allows a custom limit, enter that value using the Custom Size option.

Tip: Do not automatically choose the lowest possible quality. A slightly larger image can often provide noticeably better visual quality.

Compress Image Without Losing Quality

It is not always possible to reduce every image to a very small file size without any visible quality change. Compression works by reducing the amount of information stored in the image.

For better results, start with a moderate quality level and compare the compressed file with the original. For website images, WebP can also be a useful option when supported by the destination website.

Image Compressor for Online Forms

Government forms, job applications, admission forms, exam applications and other online services may have specific image-size requirements. A photo that looks perfectly fine on a phone can still be rejected if its file size is larger than the allowed limit.

Instead of using complicated desktop software, you can use an image size reducer online to prepare the file before uploading it to the required website.

Why Reduce Image File Size?

  • Faster image uploads
  • Lower storage requirements
  • Smaller email attachments
  • Better website performance
  • Easier sharing through messaging apps
  • Meeting online form upload limits
  • Reducing unnecessary image data

Image Compression for Websites

Images are an important part of modern websites, but large image files can increase the amount of data that visitors need to download. Compressing images before publishing them can help reduce unnecessary file size.

For websites, choose an appropriate image dimension as well as a suitable compression level. A very large image does not always need to be served when the displayed image is much smaller.

JPG vs PNG vs WebP

Format Common Use Compression
JPG Photos and general images Good for reducing photographic image size
PNG Graphics, screenshots and transparency Useful when image quality and transparency matter
WebP Modern websites and web images Often suitable for smaller web image files
