How this tool works

About Image Compression

Use Image Compression when your main goal is making a picture lighter for upload, sharing, or storage without opening desktop software. This page works well for common tasks such as compressing JPG product images, shrinking screenshots for messaging, or reducing PNG size before sending files to a form or CMS.

Best use cases

  • Compress product images before publishing
  • Reduce screenshot size for chat, email, or forms
  • Shrink images for website uploads or CMS limits
  • Batch clean up large folders of pictures before sharing

Outputs and limits

  • Batch ZIP download for multiple processed images.
  • A clear size comparison and reduction summary.
  • Support for common raster formats used in everyday delivery workflows.

Steps

  1. Upload one or more images that you want to make smaller.
  2. Choose a compression method, output format, and optional target size or dimension settings.
  3. Run compression, compare original versus processed size, and download the result or batch archive.

How to judge the compressed image

The size comparison reports bytes saved, not visual quality. Open the exported file at the size where it will be used and check text, fine edges, gradients, and transparency before replacing the original.

  • A target-size setting is a goal, not a guarantee; detailed images may need more bytes to remain clear.
  • If you also need a different format, use Image Format Conversion and verify that transparency is preserved.

Common questions

Can I compress multiple images at once?▾
Yes. The tool supports batch input and batch download when multiple results are available.
Can I compress an image to a target size like 500KB?▾
Yes, when you use the target-size style settings. Extremely small targets may still fail if the source image cannot be reduced that far cleanly.
Will the image dimensions always change?▾
No. Dimension changes depend on the selected compression method and settings.
What if I need a different output format too?▾
Use Image Format Conversion when format change is the main goal, or combine it with compression as a follow-up step.
