What this tool does

An image compressor re-encodes a photo at a lower quality setting to shrink its file size — useful for faster page loads, smaller email attachments, or upload limits — while keeping the picture looking essentially the same at normal viewing sizes.

How it works

  1. Upload the image you want to shrink.
  2. Drag the quality slider and watch the before/after file size update live.
  3. Download the compressed file once you're happy with the size/quality trade-off.
Example: Upload a 4.5MB JPG photo and compress it at 75% quality — it typically comes out around 800KB–1.2MB, roughly a 75–80% size reduction with only minor, hard-to-spot quality loss.
Yes. The image compressor is completely free, with no signup, no watermark, and no limit on how many times you use it.
No installation is needed — it runs entirely in your browser, on desktop or mobile, and works the same way on Windows, Mac, iOS, and Android.
It handles image upload -> compressed image. If your file is in a different format, use the Image converter tools linked from this page first.
Your file is used only to generate your result for this one task. It is not stored long-term, shared, or used for anything else.
