Compress Image to 100KB
Make any photo 100 KB or smaller while keeping it as clear as possible. Ideal for university admissions, scholarship portals and documents that must stay under 100 KB.
How to compress an image to 100KB
- Choose your photo (JPG, PNG, WebP or a phone photo).
- The maximum size is already set to 100 KB. Change it if your form asks for something else.
- If the form needs exact dimensions, choose “Exact pixels” and enter the width and height.
- Download the result. The exact file size is shown before you download.
Frequently asked questions
How do I reduce a photo to 100 KB?
Choose the photo and the tool automatically finds the highest JPEG quality that keeps the file under 100 KB. If quality alone is not enough, it also reduces the dimensions slightly.
Can I compress a scanned document to 100 KB?
Yes. Scans of certificates and ID cards usually fit under 100 KB at a readable quality. Crop away the empty margins first for the clearest result.
What if the form also has a minimum size?
Tick “The form also needs a minimum size” and enter it. If a small image is below the minimum, the file is padded with harmless data so it meets the requirement without changing the picture.
Are my photos uploaded to a server?
No. The image is processed by your own browser. It never leaves your phone or computer, so it is safe for ID photos and personal pictures.
