Compress Image to 20 KB

20 KB is the number that appears most often in Indian exam and recruitment notifications: signatures typically have to be 10 to 20 KB, and many photo slots start or end at 20 KB. This page is preset to that limit. Drop your passport-size photo or signature and you get a JPG just under 20 KB, at the highest quality that fits.

Where a 20 KB limit shows up

• Signatures for SSC, IBPS, RRB and state recruitment forms (often 10 to 20 KB)
• Passport-size photos for admission, scholarship and admit-card portals with a 20 KB cap
• Photos with fixed dimensions such as 200 × 230 px for bank exam applications
• Compact ID photos for employee and student databases

How to compress a photo to 20 KB

1. Drop your photos on the upload box, click to choose files, or paste an image with Ctrl+V. The target is already set to 20 KB.
2. Many forms fix both the file size and the pixel size, for example 200 × 230 px for the photo and 140 × 60 px for the signature. Open Resize, choose Exact and type the numbers; the size stays exact while the tool fits 20 KB.
3. Each image is compressed automatically; the file list shows the new size next to the original.
4. Drag the before/after slider to check the quality. The result line shows the new dimensions, the file size and the JPG quality that was used.
5. Click Download, or Download all (ZIP) when you compressed several images.

What fits in 20 KB

A 200 × 230 px photo fits in 20 KB at high JPG quality, usually 70 to 80%, so it looks clean. You can even go to around 300 × 400 px before the face starts to lose detail. A 140 × 60 px signature is only a few kilobytes, which brings up the opposite problem: some forms reject files below 10 KB. In that case enlarge the pixel size under Resize → Exact (for example 280 × 120 px) and run it again. Keep JPG as the output; exam portals almost always accept only JPG/JPEG.

Behind the scenes the tool does not guess. If your photo is over 20 KB, it runs a quick search for the highest JPG quality (up to 80%) that still lands under the limit, keeping about 1.5% headroom so the portal's own byte count never tips it over. Only when even 35% quality is too big does it scale the width and height down, step by step, and search again. If you set an exact pixel size under Resize, the dimensions are never changed: the quality may go lower instead, and a warning appears if 20 KB cannot be reached at that size.

Tips for the best result at 20 KB

• Use a recent photo with a plain white or light background; flat backgrounds leave more of the 20 KB for the face.
• Photograph the signature in daylight on white paper, then crop so the ink fills most of the frame.
• Name your files clearly (photo.jpg, sign.jpg) with the file name pattern under More options, so you upload the right one to the right slot.

Need a proper passport photo first? Create one with the passport photo maker, set any other dimension with the custom image resizer, or use compress to 50 KB when the photo slot allows 20 to 50 KB.
