Advanced Pixel Editor

Stop leaving WordPress to edit your images. Advanced Pixel Editor brings Photoshop-grade image processing — powered by ImageMagick — directly into your dashboard. Select any image from your Media Library, fine-tune contrast and sharpness with live preview, and save the result without ever opening a desktop app.

Advanced image editing within WordPress. Sigmoidal contrast adjustment and unsharp masking — the same core algorithms used by Photoshop and Lightroom — with precision sliders that update the preview instantly. Drag the built-in before/after comparison slider to evaluate your edits side-by-side with the original.

Works right where you already are. Open the editor from the Media Library grid view, list view, or attachment edit screen. Your edited image can be saved as a new file or used to replace the original (with automatic backup and one-click restore).

What You Can Do

• Sigmoidal Contrast — The same gradual, tone-preserving contrast curve used by Photoshop and Lightroom
• Unsharp Mask — Professional sharpening with independent amount, radius, and threshold controls — identical to Photoshop’s Filter → Sharpen → Unsharp Mask
• Real-time Preview — Every slider change renders instantly via ImageMagick on the server
• Before / After Slider — Draggable comparison overlay to evaluate edits at a glance
• Save As New or Replace — Keep the original untouched, or overwrite it with automatic backup
• Restore Original — One click to revert a replaced image
• Deep Media Library Integration — “Advanced Editor” buttons in grid modal, list view, and attachment page
• Fully Responsive — Works on desktop, tablet, and mobile
• Accessible — Full keyboard navigation, ARIA labels, and screen reader support

Upgrade to Pro

Need more than contrast and sharpening? Advanced Pixel Editor Pro adds a full Photoshop-style toolset on top of the free editor:

• Advanced Filters — Photoshop-style Levels and Curves dialogs, plus brightness, saturation, hue, clarity, dehaze, vibrance, highlights/shadows, and artistic effects like sepia, vintage, duotone, and black & white
• Crop & Resize — Interactive crop overlay with aspect ratio presets (free, 1:1, 4:3, 16:9), resize with aspect lock, and DPI controls
• Watermarking — Text watermarks with 50+ Google Fonts or image watermarks with transparency, plus 9-point positioning and tiling
• Batch Processing — Apply filters to 10–100+ images at once with real-time progress, pause/resume, and background processing — like Photoshop’s Actions, but built into WordPress
• Filter Presets — Save and reuse your favorite filter combinations

Plans start at $49/year (1 site) with lifetime options available. 20% of all Pro proceeds are donated to the ImageMagick project — the open-source library that powers this plugin and millions of websites worldwide. View pricing and features →

Requirements

This plugin requires the ImageMagick PHP extension (Imagick), which is available on most modern hosting platforms. If your host doesn’t have it enabled, contact them — most providers enable it within hours. Imagick is a worthwhile upgrade that also improves WordPress core image handling.
