SiteByter Image Optimizer

Description

SiteByter Image Optimizer compresses every JPG and PNG in your WordPress media library using the image editor already built into WordPress (GD or Imagick). No images leave your server. No API keys. No account. No per-image charges. No monthly quotas. Just faster pages.

Why Local Optimization?

Local optimization means your images are compressed right on your server using WordPress’s built-in image editor. Benefits include:

• Images never leave your server — complete privacy
• No dependency on external services
• No API key or account registration required
• No per-image charges or monthly usage limits
• Works offline and on any hosting environment

Why Cloud Optimization Matters

Modern WordPress sites increasingly store media on cloud storage — Amazon S3, Cloudflare R2, DigitalOcean Spaces — for performance, scalability, and cost. But most image optimization plugins can’t touch those files because they only process local images.

With SiteByter Pro, cloud-stored images are automatically downloaded, compressed on your server using the same high-quality local engine, and re-uploaded. No manual work. No separate tools. One plugin handles everything.

What Makes This Plugin Different?

This plugin processes images entirely on your server using WordPress’s built-in image editor (GD or Imagick). No images are uploaded to an external service, no API key is required, and there are no per-image limits or monthly quotas. With the Pro upgrade, the same local compression engine can also handle images stored on cloud storage providers.

How It Works

1. Install and activate — no signup, no API key, no configuration needed to start.
2. Set your quality — the slider lets you balance file size vs. visual quality. 78–85 is the sweet spot.
3. Click Bulk Optimize — processes your entire library with a progress bar and per-image log.
4. New uploads handled automatically — auto-optimize compresses every future upload instantly.
5. Changed your mind? — restore originals from backup and re-optimize at different settings.

Pro: Optimize Images on Cloud Storage

If your WordPress media lives on Amazon S3, Cloudflare R2, DigitalOcean Spaces, Wasabi, or Bunny Storage, Pro handles it automatically. Images are downloaded, compressed locally, and re-uploaded — all without manual intervention. Hand-rolled AWS Signature Version 4 signing in pure PHP with zero external dependencies.
