Choose a quality that fits the task

Lower quality reduces file size. The right choice depends on the photo and where you will use it.

What compression changes

Use the controls to balance visible detail against file size, then check the result before sharing.

Quality controls visible detail

Lower values remove more data and can soften fine texture.

Smaller files are easier to send

They are useful for upload limits, email attachments, and web pages.

A target size is a limit, not a promise

Complex images may not reach a very small target without heavy quality loss.

Choose the format for the destination

Compressing and converting are separate choices. Keep the source format unless the place you share to needs another one.

Use JPEG for

  • Photos and natural scenes with many colors
  • Email attachments and common upload forms
  • Places where broad compatibility matters

Keep PNG or choose WebP when

  • You need transparency or sharp graphic edges
  • The image contains logos, text, or interface screenshots
  • You know the destination accepts WebP
