Resize any image to 20KB in your browser

Need a picture that's 20 kilobytes or smaller? Whether it's for an online form, an exam registration, a marketplace listing or an email attachment, this page targets exactly 20KB. Drop your JPG, PNG or WebP above, and PixelPress does the maths for you.

Why an exact size matters

Many upload forms reject anything over their limit with an unhelpful error. Instead of guessing quality percentages and re-exporting again and again, you set the ceiling once. PixelPress measures the real encoded size of the file and guarantees the result stays under 20KB.

Tips for the best result at 20KB

Keep the aspect ratio locked so the picture doesn't stretch.
Use JPG or WebP for photographs — they compress far better than PNG.
If 20KB looks too soft, try a slightly larger target or reduce the dimensions first.

Everything runs locally, so your image never leaves your device.

FAQ

Frequently asked questions

Everything about compressing images to an exact size.

How do I resize an image to 20KB?

Add your photo above, make sure the target size is set to 20 KB, and press Compress. PixelPress searches for the best quality that stays under 20KB and shows the exact final size. Then download your file.

Will the image still look good at 20KB?

PixelPress always keeps the highest quality that fits your limit. For most photos 20KB is enough to look clean on screen; if a very large image can't reach 20KB by quality alone, the tool trims the dimensions slightly so it still fits.

Is it really free and private?

Yes. There's no sign-up and no watermark, and your image is processed in your browser — it is never uploaded to a server.

Which format should I pick for 20KB?

For photos, choose JPG or WebP. WebP usually reaches 20KB at higher visual quality. Avoid PNG for tiny targets because it can't compress by quality.
