1 KB = 1024 bytes. The result stays at or just under 20 KB.

What is the Increase to 20 KB tool?

Some application forms reject photos that are too small, for example "photo must be between 20 KB and 50 KB". This tool raises the file size without changing how the photo looks.

How to use it

Upload your photo.
Type the size you need (set to 20 KB).
Click Increase size and download.

How it works

The photo is first saved at the highest JPG quality. If it is still smaller than you need, harmless empty data is added inside the file so it reaches the size — the picture itself does not change.

Example

A 12 KB photo increased to 20 KB

Before: 12 KB

After: about 20 KB

Looks exactly the same

Frequently asked questions

Is the increased file accepted by exam portals?

Yes — it is a normal JPG file. Portals check the size and dimensions, and both stay valid.

Can I increase the width and height too?

Use the Image Resizer for that. This tool only changes the file size.

Are my photos uploaded anywhere?

No. Everything happens inside your browser on your own phone or computer. Your photos are never sent to a server, so it is safe for ID cards, documents and personal pictures.
