What is Image Compressor?

An image compressor reduces image file size by re-encoding the image with a smaller output format, lower quality setting, or smaller pixel dimensions. It is useful for faster websites, lighter email attachments, and easier sharing.

How to Use Image Compressor

  1. Upload one or more images.
  2. Choose JPG, PNG, or WebP as the output format.
  3. Lower the quality slider to reduce file size.
  4. Optionally reduce dimensions for an even smaller file.
  5. Download your compressed image or ZIP.

Frequently Asked Questions

Will compression reduce quality?
JPG and WebP compression can reduce quality if the slider is lowered. A quality value around 75–85 usually keeps images visually sharp while reducing size.
Is PNG compression lossless?
PNG export is generally lossless, but it may not always produce a smaller file than the original. For photos, WebP or JPG is usually smaller.
What is the best output format for small files?
WebP usually gives the smallest file size for web use while keeping good visual quality.
Does ImageCub keep my files?
No. Files are processed locally and are not stored by ImageCub.
