Increase Image Size in KB
Increase file size (KB) to meet minimum portal requirements (e.g. Min 20KB) without losing quality.

JPG, PNG, or WEBP (Max 5MB)

We add safe padding metadata. Visual quality remains 100% identical.

New File Size
This tool adds null-byte padding to increase file size. Some strict portals may reject this. For a safer approach, use the Photo Editor to slightly upscale the image.
How to increase image size in KB
- Upload your JPG, PNG, or WEBP image by clicking the upload area or dragging the file onto it.
- Enter the target KB size your portal requires (for example 20 or 50) in the Target Size field.
- Click Increase Size. The tool adds safe padding metadata to reach the exact KB target without changing how the image looks.
- Check the new file size shown, then click Download Image to save the larger file.
This tool adds padding to grow the file. Most portals accept it, but a few strict ones may reject padded files — if that happens, use the Photo Editor to slightly upscale the image instead.
Why you might need this
Several exam and government portals reject files that are too small as well as too large. SSC and IBPS portals, for instance, ask for a photo between 20 and 50 KB — a 12 KB photo fails the “minimum size” check just as a 60 KB photo fails the maximum. When your webcam or phone export produces a very small file, this tool bumps it up to the required minimum without visibly altering the image.
The same minimum-KB rule appears on many state PSC, railway, and police recruitment portals, and occasionally on visa and scholarship forms. Because the padding is invisible metadata, the printed photo looks identical — only the file size changes.
Going the other way — your file is over the limit? Use the Compress Image tool to shrink it. If you need exact pixel dimensions plus KB control in one place, the Photo Editor is the better choice.
Common minimum KB requirements
| Portal / exam | Photo min KB | Photo max KB |
|---|---|---|
| SSC (CGL, CHSL, MTS) | 20 KB | 50 KB |
| IBPS PO / Clerk | 20 KB | 50 KB |
| RBI Assistant | 4 KB | 40 KB |
| UPSC CSE | 20 KB | 300 KB |
| Most state PSC | ~20 KB | ~100 KB |

Frequently asked questions
How do I increase my photo to 20 KB?
Upload the image, type 20 in the Target Size field, and click Increase Size. The tool pads the file until it reaches 20 KB, then you download it.
Does increasing the KB change the image quality?
No. The extra bytes are invisible padding, so the photo looks exactly the same when opened or printed — only the file size on disk changes.
Will every portal accept a padded file?
Most do, but a few strict portals validate the file structure and may reject padded images. If your form rejects the result, use the Photo Editor to slightly upscale the image instead, which increases size legitimately.
What formats are supported?
JPG, JPEG, PNG, and WEBP files can be increased to a target KB size.
Is my image uploaded anywhere?
No. All processing happens locally in your browser — the file never leaves your device.
My photo is too big, not too small — what do I do?
Use the Compress Image tool to reduce the file size down to the portal's maximum instead.
