Best settings for image compression
Start with moderate quality and keep the original dimensions when possible. Resize only when the receiving form also specifies a smaller width or height.
JPG usually gives smaller photo files, while PNG is better for graphics and transparency. Check the accepted format before changing the source image.
If the image is still too large
Reduce the dimensions, crop unused background, or lower quality a little more. Make one change at a time so faces, signatures, text, and document edges stay clear.
Keep the original image until the receiving website accepts the compressed copy, and confirm the downloaded file still meets its width, height, and format rules.
