How to Compress an Image to 150KB

  1. Click "Choose Files" or drag and drop the image you want to shrink.
  2. Leave the target set to 150KB — the compressor finds the highest quality that still fits.
  3. Download your compressed image once the size is reached.

Why 150KB?

When you need an image under 150KB

Profile photos and blog images that need to stay lightweight.

How the target is hit: the compressor re-encodes your image several times, searching for the highest quality that still lands under 150KB. Only if that is not enough does it also reduce the pixel dimensions — so you keep as much detail as the limit allows.

FAQ

Frequently asked questions

How do I compress an image to exactly 150KB?

Drop your image above. The compressor repeatedly re-encodes it, searching for the highest quality setting that still lands under 150KB. If the target is very small for the image's dimensions, it also scales the image down until it fits.

Are my images uploaded to a server?

No. Compression runs entirely in your browser using Web Workers and Canvas. Your files never leave your device — you can confirm zero network requests in DevTools.

Will compressing to 150KB ruin the quality?

The tool always keeps the best quality that fits, rather than dropping straight to the lowest setting. For a typical photo, 150KB is reached mostly by reducing JPEG quality; only when that is not enough are the pixel dimensions reduced.

Which formats can I compress?

JPG, PNG, WebP, HEIC, AVIF, TIFF, GIF, and BMP can all be read. Output is JPG by default, which gives the smallest file for photographs.

Is there a limit on how many images I can compress to 150KB?

No. The tool is free with no signup and no watermark. Batch several images at once and download them together.
