About This Tool

This tool resizes WordPress media to exact pixel dimensions, producing outputs suitable for thumbnails, social previews, and hero images. It accepts an input image, target width and height, and optional controls for aspect ratio and format.
Conceptually, the tool computes a new image size using a scale factor to preserve quality. It performs resampling with a high-quality algorithm and converts to the requested format, applying the chosen quality setting.
Who benefits: WordPress developers, agencies, and site owners who need consistent image dimensions across responsive layouts. The differentiator is precise, fast, offline-friendly processing with predictable file sizes and compatibility with the WordPress media library.
Core features include dimension targets, aspect ratio handling, output format choices, quality control, and robust error handling for invalid inputs or unsupported formats.

Frequently Asked Questions

Find Quick Answers

What formats are supported?

The tool supports JPEG, PNG, and WEBP outputs. It preserves transparency for PNGs, and applies lossy compression based on the selected quality setting. Unsupported formats are rejected with a specific error code.

Can I preserve the original image?

Yes; the tool generates a new output file, leaving the source intact. It can overwrite if you choose to replace in WordPress, but the default is to create a separate resized copy.

Is batch resizing supported?

Batch processing is not supported in a single run. To resize multiple images, run the tool separately for each image or integrate batch logic in a workflow.
