How to compress images for WordPress

Prepare images before you upload them to WordPress so editors get smaller media files without sending private originals to a third-party compressor.

Compress an image privately

Useful for site owners, bloggers, and small teams who publish photos, screenshots, and product images in WordPress. PixPact processes images locally in your browser; no image upload is required.

A practical workflow

  1. Keep the original file as a backup, then open PixPact and select the output format your theme supports.
  2. Use WebP for most photographic images, PNG when transparency or crisp interface edges matter, and JPEG for broad compatibility.
  3. Start around 75% quality for lossy formats, compare the result at the rendered WordPress size, and download only after the result is ready.
  4. Upload the compressed file with a descriptive filename and add useful alternative text in WordPress.

Before you publish

  • Check the image on mobile
  • Keep width close to the largest display size
  • Avoid uploading several duplicate originals
  • Measure page speed after publishing

Common questions

Should I compress before or after uploading to WordPress?

Compressing before upload reduces storage and transfer immediately. A WordPress optimization plugin can still create responsive sizes afterward.

Is WebP always the best WordPress format?

WebP is a good default for modern themes, but PNG remains useful for transparency and JPEG can be a safer choice for legacy integrations.
