What is Image Compressor?

Large images slow down websites and consume unnecessary storage. This tool compresses images directly in your browser, reducing file size by up to 80% while preserving as much visual quality as possible — no uploading to a server required.

How to Use Image Compressor

  1. Click the upload area or drag and drop your image onto it.
  2. Use the quality slider to choose a compression level (1–100%). 70–85% is usually the sweet spot.
  3. Optionally set a maximum width or height to also resize the image.
  4. Select the output format (JPEG, PNG, or WebP), then click Compress and download the result.

Frequently Asked Questions

WebP typically achieves the best compression with excellent quality, followed by JPEG. Use PNG only when you need transparency or lossless quality, as it produces larger files.

For web images, 75–85% quality is usually ideal — it produces a significant file size reduction with barely noticeable quality loss. Go lower (50–70%) for thumbnails or background images.

No, unless you explicitly set a max width or height. Compression only reduces file size. Use the resize inputs if you also want to change dimensions.

Yes. Images are processed entirely in your browser using the Canvas API. No data is ever uploaded to a server.
