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.

Frequently asked questions

What is a 300KB image limit usually for?

Many marketplaces, real-estate sites and classified ads accept product or property photos up to about 300 KB. It's also a good ceiling for full-width website photos.

Will compressing to 300KB keep the full resolution?

Usually yes, up to 2,048 pixels wide, which this page keeps. Very detailed photos may need slightly lower quality, and the image is only shrunk if quality alone can't reach 300 KB.

Does the 300KB compressor remove GPS data from photos?

Yes. Re-encoding the photo drops EXIF metadata, including the camera model and location, which is good for privacy before you post listings online.
