How to Reduce Image Size in KB

By FreeNation Softwares · Updated 2026-10-18

Upload forms and websites often set a maximum file size in KB. Here's how to get any photo under the limit — exactly — without obvious quality loss.

How to reduce image size in KB

Open the Compress Image tool —
Pick your target — 10, 15, 20, 30, 50, 100, 200, 300 or 500 KB, or type a custom KB.
Upload your photo —
Download — The result lands under your chosen KB.

💡 Pick the largest KB the form allows for the clearest photo. Going too low makes faces look soft.

Ready? Use the Compress Image tool — free, and your file never leaves your device.

Can I target an exact KB?

Yes — pick a preset or type a custom KB; the result fits under it.

Will it blur my photo?

Only if you pick a very low KB; use the highest allowed.

Is it free?

Yes, and private.
