Reduce image size in KB
Use this image compressor when a form says the photo must be under 20KB, 50KB, 100KB or any other limit. Type the target size in KB and the tool compresses the JPG or PNG to match it as closely as possible.
It is useful for exam and job applications, scholarship forms, college admissions and any site that rejects large photos.
How to use this tool

- Enter the file size you need in KB, for example 50.
- Click Compress & Download to save the smaller image.
Frequently asked questions
How do I compress a photo to 50KB?
Upload the photo, type 50 as the target size and download. For other limits just change the number. If the form is strict, enter a value a few KB below the limit.
How can I reduce image size without losing quality?
Keep the target size as high as the form allows and crop away empty space first. Smaller pixel dimensions need less compression, so the photo stays sharper.
Which image formats are supported?
You can compress JPG, JPEG and PNG images. The result is saved as a JPG because it gives the smallest file size.
Are my photos uploaded anywhere?
No. The tool runs in your browser, so the image stays on your phone or computer.
