How to resize an image to 20KB
- Tap Choose an image and pick a photo from your gallery or files. You can also paste a screenshot.
- The target is already 20 KB. Change it if your form asks for something different.
- Pick the format you need: JPG, JPEG, PNG or WEBP.
- Wait a moment for the green "Ready" message, then tap Download.
How the 20 KB compression works
First the tool lowers JPG quality in small steps until the file fits under 20 KB, because that removes detail your eyes barely notice. If even that isn't enough, it also reduces the width and height. That's why a large phone photo may come out a few hundred pixels smaller than the original: it's the best way to stay sharp at 20 KB. The result panel shows the final size and dimensions before you download.
If you need both an exact pixel size and a KB range, such as 200 × 230 px and 20–50 KB, use the exam photo tool instead. It crops to the right shape and keeps the file above any minimum size too.
Tips for a clear 20 KB photo
- Crop away empty space first; fewer pixels to store means more quality per pixel.
- Choose JPG for photographs. PNG files are much larger and need a bigger pixel reduction to reach 20 KB.
- Start with a sharp, well-lit photo. Compression can't fix blur or darkness.
- If your form allows a range, aim near the top of it, for example 19 KB instead of 20 KB, for extra clarity.
Where 20 KB images are needed
Many application forms set 20 KB as the minimum or maximum for photos and signatures, including bank exams (IBPS and SBI photos are 20–50 KB) and signature uploads for SSC and bank exams (10–20 KB). Check your form's exact rules and see our pages for IBPS, SSC and NEET.

Frequently asked questions
How do I reduce a photo to 20KB?
Add your photo to the tool on this page, keep the target at 20 KB, and download. The tool compresses it automatically until it is under 20 KB.
Will my photo lose quality at 20KB?
Some detail is always lost when a multi-MB photo is reduced to 20 KB, but the tool lowers JPG quality first and only then reduces pixel size, which keeps it as clear as possible.
Can I resize a PNG to 20KB?
Yes. You can download as PNG, but PNG is lossless, so the tool has to reduce the pixel size more to reach 20 KB. Choose JPG for photos if the form allows it.
Is my photo uploaded anywhere?
No. The compression happens entirely in your browser on your own device.
Can I get exactly 20 KB?
The tool keeps the file just under 20 KB. If your form needs a minimum size as well, use the exam photo tool, which keeps the file inside both limits.
