Reduce photo size to any KB you need
Every website seems to have a different limit: 30 KB here, 150 KB there, 300 KB somewhere else. Instead of guessing with a quality slider, type the exact number of kilobytes your form allows and the tool does the rest.
How it works
- Type your target size in KB (or tap a quick size).
- Select your images.
- The tool tests many quality levels and keeps the sharpest version that is still under your limit.
MB to KB — quick reference
- 1 MB = 1024 KB
- A typical phone photo: 2–6 MB (2,000–6,000 KB)
- Most job and admission forms: 50–200 KB
- Signatures: 10–30 KB

Frequently Asked Questions
Can I reduce an image from MB to KB?
Yes. Type the KB limit you need and the tool converts multi-MB photos down to that size.
What is the smallest size possible?
You can go down to 5 KB, but below 15–20 KB photos lose a lot of detail.
Which format is the result?
JPG, because it gives the smallest files for photos and every website accepts it.
Is it free?
Yes, completely free with no limits.
