Description
PicEte Image Optimizer brings professional-grade image optimization to WordPress at no cost.
Key Features:
- Unlimited Smart Lossy Compression — Adjust quality from 1-100 with a simple slider, or let the content-adaptive engine pick a perceptually-lossless setting per image (photo / UI / flat graphics). A Never-Worse guard guarantees the output is never larger than the original.
- WebP Conversion — Convert images to next-generation WebP format automatically, with a visually-lossless tier for UI / logo / transparent (non-photo) images.
- AVIF Output (Batch) — Optionally generate AVIF copies during bulk/Cron optimization; served to supporting browsers via when smaller than the original.
- Multiple Size Support — Optimize full-size images and thumbnails in one pass.
- Privacy First — All processing happens locally on your server by default. No external calls, no data leaves your site. An optional cloud API tier (reSmush.it / TinyPNG) is available but disabled by default and requires explicit opt-in.
- Secure Backups — Automatic backup before optimization with configurable retention.
- Flexible Drivers — Quality-first engine: prefers fast system CLI tools (jpegoptim, cjpeg, pngquant, optipng, oxipng), then Imagick, then GD.
- Batch Processing — Re-optimize existing media library with cursor-based bulk optimization.
- Zero Ad Experience — Clean backend without upgrade prompts, affiliate links, or commercial banners.
- Online Tools at PicEte.com — Free browser-based image compression, WebP conversion, and format comparison tools.
Why PicEte?
Most image optimization plugins either charge for advanced features or flood your admin panel with ads. PicEte takes a different approach: powerful, unlimited optimization completely free, supported by PicEte.com.
Typical Savings:
- JPEG: 40-70% size reduction with content-adaptive quality
- PNG: 30-60% size reduction with lossless optimization and smart quantization
- WebP: Additional 25-35% savings over JPEG

Performance Considerations:
Large images may take several seconds to process. For sites with many images, use the bulk optimization feature which runs via cursor-based pagination.
CLI Tools (Optional):
For best performance, install jpegoptim and pngquant on your server:
`bash
Ubuntu/Debian
sudo apt-get install jpegoptim pngquant
CentOS/RHEL
sudo yum install jpegoptim pngquant
`
The plugin automatically falls back to Imagick or GD if CLI tools are unavailable.

FAQ
-
Does this plugin send my images to external servers?
-
No. By default all image processing happens locally on your server using PHP extensions or CLI tools, and your images never leave your site. The only exception is the optional cloud API tier (reSmush.it / TinyPNG), which is disabled by default and only sends images to a third-party server after you explicitly enable it on the settings page.
-
How does the comparison slider work?
-
The Media Library gets an “Optimize & Compare” button that opens a side-by-side slider. Drag the handle to instantly see the difference between original and optimized versions. This helps you find the perfect quality setting for your images.
-
What backup options are available?
-
Original images are automatically backed up to
wp-content/uploads/picete-backups/before optimization. The directory is protected with.htaccess(Apache) ordeny all(Nginx) rules. You can configure retention period (e.g., 30 days) and maximum total backup size (e.g., 5 GB) in settings. Backups can be restored individually or in bulk. -
Can I bulk-optimize existing images?
-
Yes. Navigate to Media > Library and use the “Bulk Optimize” button. The plugin processes images in the background using cursor-based pagination, handling tens of thousands of images reliably. Progress is tracked and you can pause/resume at any time.
-
What are the server requirements?
-
- PHP 7.4 or higher
- WordPress 6.0 or higher
- One of: Imagick extension, GD extension, or CLI tools (jpegoptim, pngquant)
System CLI tools are preferred when installed; the plugin automatically falls back to Imagick or GD otherwise.
-
Is this really free?
-
Yes, completely free. No ads, no upgrade prompts, no limits. Powered by PicEte.com as a brand extension to the WordPress community.
