150 KB is a sweet spot for blog images, website banners and email newsletters: sharp on screen and quick to load. Drop your photos to get each one under 150 KB at the best quality the compressor can find.

How to use the Image Compressor

  1. 1Drop one or more images (JPG, PNG, WebP or AVIF) onto the box, or tap it to choose files.
  2. 2Choose Quality to set the level yourself, or Target size to enter the file size you need, such as 100 KB.
  3. 3Pick the output format and, if you like, a maximum width. WebP usually gives the smallest file.
  4. 4Download each image, or all of them as one ZIP file. Everything happens on your device.

Frequently asked questions

Is 150KB a good size for blog images?

Yes. A 1,920-pixel-wide photo at about 150 KB looks sharp on most screens and keeps pages quick on mobile data. Smaller inline images can go lower.

Should I use WebP instead of JPG at 150KB?

If your website supports WebP (almost all do now), WebP keeps more detail at the same 150 KB. Switch the output format to WebP before you drop your images.

Can I compress a whole folder of images to 150KB?

Up to 20 at a time: each one is compressed to the target on its own, and you can download them together as a ZIP file.
