How to Reduce Image Size to 100KB, 50KB or 20KB (Free)
Step-by-step ways to shrink a photo to an exact KB limit for online forms, applications and upload portals — without blurring it.
Job applications, scholarship portals and government forms often cap uploads at 100 KB, 50 KB or even 20 KB. A modern phone photo is 3–8 MB, so you need to shrink it by 95% or more. Here is the fastest reliable way.
The fastest method: set a target size
Open Compress Image to Exact Size, drop in your photo and type the limit — for example 100 KB. The tool tries different quality levels until the file fits under your target. Landing pages also exist for the most common limits: 100 KB, 50 KB and 20 KB.
Compress Image to Exact Size
Compress an image to an exact KB size — free, no upload.
Do it manually in three steps
- Resize to the displayed size. There is no reason to upload a 4000 px photo for a 400 px slot. Resize the image first.
- Compress. Lower the quality in 5–10% steps and check the size after each step.
- Try WebP or JPG. JPG is almost always smaller than PNG for photos. If the form accepts it, WebP can be smaller still.
What if the file is still too big?
- Crop away unnecessary background with the Image Cropper.
- Reduce pixel dimensions further — halving width and height cuts the file to roughly a quarter.
- Convert PNG screenshots to JPG with PNG to JPG.
Frequently asked questions
Will my photo look blurry at 100KB?
Not if you resize it first. A 600×800 px photo at 100 KB looks clean; a 4000 px photo squeezed to 100 KB will not.
How do I compress an image to 20KB?
Resize it to a small size (for example 300×300 px), then use the 20 KB compressor so the quality is lowered only as much as needed.
Is it free and private?
Yes. FileDagadu compresses images inside your browser — nothing is uploaded or stored.
