Privacy and limits

  • Images stay in your browser and are not uploaded.
  • Very large files depend on your browser memory.
  • AVIF export depends on browser support.

What this tool is best for

Use this general compressor when you are not sure whether JPG, PNG or WebP will give the best result. It lets you compare output formats from the same source file.

The max width setting is useful for turning camera photos into web images before quality compression runs.

Common use cases

  • Blog images that need faster loading
  • Email attachments that are too large
  • CMS uploads with practical file-size limits

Format notes

  • WebP usually gives the smallest result for mixed web images.
  • JPG is often best for photos that do not need transparency.
  • PNG is useful when sharp text or transparent graphics matter more than file size.

Original test sample

  • A 2400 x 1600 JPG photo can often shrink strongly when exported as 1600px WebP at 75-85 quality.
  • A screenshot-style PNG may shrink more by converting to WebP than by keeping PNG output.
