100KB upload limit
Make a smaller image when a form, profile, exam portal, or application rejects files over 100KB.
Compress Image to KB
Compress an image toward a target KB size locally for upload limits, forms, profiles, and portals.
Choose a JPG, PNG, or WebP image, pick a target such as 50KB, 100KB, 200KB, or 500KB, and download a smaller JPG or WebP copy.
Target-KB searches are strong ad-supported utility intent because users usually arrive after a portal, exam site, job application, or profile upload rejects their file.
How to use this free image tool
- Open the image to KB compressor and select one JPG, PNG, or WebP image.
- Choose a target such as 50KB, 100KB, 200KB, 500KB, or a custom KB value.
- Review the preview, estimated file size, and whether the target was met.
- Download the smaller image and open it before submitting it to the destination portal.
Good use cases
Job application
Reduce a headshot, ID-style photo, or document image before uploading to a job portal.
School or exam portal
Create a smaller copy for strict online forms without sending the original image to another site.
Privacy and limits
Selected image files are loaded into your browser and are not uploaded by the target-size compressor.
The free version processes one image at a time. Extremely small KB targets may require lower quality or smaller dimensions and may not be visually acceptable.
Frequently asked questions
Can it always hit 100KB?
Not always. The tool tries several quality and size combinations and shows the closest result if the target would make the image too small or blurry.
Are images uploaded?
No. Target-size compression runs locally in your browser.
Which format should I use?
JPG is a safe default for photos. WebP can be smaller when the destination site accepts it.
