Complete Guide to Using Image Compression Tools

Image compression tools reduce file size by adjusting encoding quality and pixel size, making it suitable for website performance, email attachments, and social uploads. The best setting depends on the content: photos can tolerate more lossy compression, while text screenshots and transparent images need to preserve sharp edges.

Operation steps

  1. Load images and record original and file sizes
  2. Adjust quality or output size and zoom in to inspect details and ribbons
  3. Select smaller results with acceptable image quality and download

Practical suggestions and limitations

Scaling down to actual display size first is often more effective than just reducing quality. Do not overwrite the unique original image with the compressed file to avoid cumulative losses when exporting again in the future.

Privacy and native processing

Compression is done using the browser's Canvas and encoding capabilities, images are not uploaded.
