What you get

You get smaller image files without processing every picture by hand.

You can reduce the storage your images take up and make them smaller to send or upload. Image optimizer Compression handles PNG, JPG, BMP, and TIFF compression, with lossless compression available for PNG images so you can reduce their size without losing image quality.

You can drag in individual pictures or an entire folder, letting the app identify images and compress them in batches. If you want the smaller files to take the place of your originals, you can use automatic replacement rather than swap each file yourself.

You also get image format conversion, with support covering PNG, JPG, HEIC, BMP, TIFF, PSD, AI, and several camera RAW formats. That gives you a way to handle compression and format changes in one app instead of relying on browser-based tools.

  • Keep PNG quality

    You can shrink PNG files with lossless compression, preserving image quality.

  • Process folders at once

    You can drop in a whole folder and compress its images in batches instead of selecting each picture individually.

  • Avoid manual file swaps

    You can have compressed images automatically replace the originals.

  • Change image formats

    You can convert image formats, with support for common image types and several camera RAW formats.

Best for

  • You regularly prepare images for uploading or sending
  • You have folders of pictures to compress in batches
  • You need both image compression and format conversion

Skip it if

You don't need it if your images are already small enough and your existing tools handle the format conversions you need.
