Image Compressor

Compress JPG, PNG, and WebP images to a smaller file size right in your browser — no upload.

About the Image Compressor

Reduce the file size of your images without uploading them anywhere — all compression happens in your browser using the HTML canvas, so your photos stay private. Lower the quality slider to shrink the file; JPEG and WebP give the best size savings.

Tips

  • WebP usually produces the smallest files at the same quality.
  • For photos, 70–80% quality is a good balance of size and clarity.
  • PNG is lossless — use it only when you need transparency or exact pixels.
