Compress a photo to 20 KB in one step
Type or pick the limit, drop the image, and the tool returns a JPG that is at or under 20 KB. It is built for the forms that enforce exact sizes: signature uploads on exam and job portals, profile photos on application forms, thumbnails for very slow connections. Most Indian and Pakistani recruitment portals ask for a signature between 10 and 20 KB, and a passport photo between 20 and 50 KB.
A signature scan comes out crisp at 20 KB; a face photo stays recognisable at roughly 300–400 pixels wide. A detailed landscape will look soft – 20 KB simply does not hold much picture. The result size is shown before you download, so there is no guessing and no re-uploading to find out whether the portal accepts it.
How to reduce an image to 20 KB
- Add the image. Click the sheet or drag the photo onto it. JPG, PNG, WebP, HEIC (iPhone), GIF, BMP and AVIF all work, and you can add several at once.
- Keep 20 KB as the target. It is pre-filled. Change it if the form says a different number – the presets cover 20 KB to 1 MB.
- Choose the output format. JPG gives the smallest file for photos and scans. Use PNG only when the portal insists on it or the image is a logo with flat colours.
- Press Compress. The tool tries quality levels first, then resolution, until the file fits. The new size and dimensions appear on the thumbnail.
- Download. One image downloads directly; several come as a ZIP. Nothing is stored anywhere.
What happens to the picture
Every JPEG has a quality setting from 1 to 100. Phone cameras save at 90–97, which is far more than a form needs. Dropping to 75–85 removes about half the file with no change you can see at normal size. If that is not enough for 20 KB, the tool reduces the pixel dimensions in small steps and checks the size after each one, stopping as soon as it fits. It never goes below 32 pixels and tells you if the limit was impossible for that image.

Frequently asked questions
How do I compress an image to 20 KB without losing quality?
Pick the image, keep 20 KB as the target and press Compress. The tool lowers JPEG quality first, which is invisible at the top of the range, and only reduces resolution if quality alone is not enough. A signature scan comes out crisp at 20 KB; a face photo stays recognisable at roughly 300–400 pixels wide. A detailed landscape will look soft – 20 KB simply does not hold much picture.
Can I compress a PNG to 20 KB?
Yes. For the smallest file choose “JPG” as the output; PNG cannot be compressed by quality, so a PNG target of 20 KB is reached by shrinking the dimensions instead, which suits logos and screenshots but not photos.
Which portals need 20 KB images?
Most Indian and Pakistani recruitment portals ask for a signature between 10 and 20 KB, and a passport photo between 20 and 50 KB.
Is the photo uploaded to your server?
No. Compression runs in your browser with JavaScript. The image never leaves your device, which also makes it quick on slow connections.
Can I do several photos at once?
Yes. Add as many as you like; each one is compressed to 20 KB and you receive a ZIP. There is no limit and no watermark.
