Is the file really under 20 KB?

Yes. The size is measured directly from the generated file (blob.size / 1024), not estimated, and the loop repeats until the value is inside your bracket.

Are my images uploaded anywhere?

Never. There is no upload endpoint in this application; the photo is processed on your device and disappears when you close the tab.

Resize Image to 20 KB Online

Many government and university portals reject a photograph the moment it crosses 20 KB, and others quietly reject files that are far too small. This page opens the resizer already locked to a 15 KB minimum and a 20 KB maximum, so the exported file always lands inside the accepted window. Choose your photo, set the pixel dimensions the form asks for, and pick Smart Fit & Center so the face is never stretched or squashed. The engine keeps the original full-resolution image in memory, applies a multi-step sharpening downscale, and then binary-searches the JPEG quality between 0.05 and 1.0 until the true byte size measured from the blob sits inside the bracket. Every step runs inside your own browser using the Canvas API and Web Workers — no upload, no server, no account.

Frequently asked questions

No. The image is downscaled in successive halving steps with high-quality interpolation before compression, so edges, eyes and text stay crisp even at a small file size.
