How it works

The image is decoded, optionally resampled, and re-encoded with a format-specific quality or compression setting; lossy codecs discard information while lossless codecs preserve pixels. Metadata may be retained or removed separately from image data.

  • Quality settings trade file size against quantization artifacts.

Worked example

Compress for Web
Compress an image to 70% JPEG quality for faster web loading
Input
											data:image/png;base64,iVBORw0KGgo... (image data URL)
Output
												JPEG data URL encoded at 70% quality

When to use this

Web uploads, email attachments, and asset builds compress images.

Edge cases

  • Repeated JPEG re-encoding compounds blocking and ringing artifacts.
  • PNG compression cannot reduce photographic noise as effectively as a lossy codec.
  • Removing metadata can discard orientation or color-profile information.
