Simply paste from your clipboard or drag and drop any image directly into the editor, set a filename, choose your preferred format (ORIG, WebP, PNG), and it will be processed and uploaded directly to your media library. #### Key Features * **Clipboard Paste & Drag-and-Drop**: Seamlessly catches images pasted or dropped into the Gutenberg editor. * **Direct Featured Image Drag-and-Drop**: Drop photos directly onto the Gutenberg sidebar ‘Featured Image’ panel to automatically convert to WebP and set as the post’s featured image. * **HEIC / HEIF Format Support**: Easily drag & drop or paste photos from Google Photos and Apple iOS devices; automatically decoded and converted on-the-fly to WebP/JPG/PNG. * **Multi-Image Drag-and-Drop Gallery**: Drop multiple images at once to batch process them and insert them as a Gutenberg Gallery block. * **Keep Original Format (ORIG)**: Supports an ‘ORIG’ option to upload files directly without re-compression, preserving GIF animations, AVIF compression, and original qualities. * **Smart Block Placement & Replacement**: Inserts images at exact drop locations, replaces empty paragraph blocks, or updates existing image blocks upon drop. * **Smart Dimension Detection & Upscaling Control**: Detects and displays natural image width directly on the Orig button, prevents accidental blurriness by disabling larger presets by default, and includes a toggle to allow upscaling when needed. * **Client-side Image Conversion**: Converts raw image data directly in your browser using HTML5 Canvas for ultra-fast processing. * **Format Selection**: Choose between ORIG, WebP, and PNG formats with dynamic format detection. * **Smart Size-Guard & Auto Fallback**: Automatically preserves the original format if converting would increase file size, preventing unnecessary bloat and quality loss. * **Custom Filename & Alt Text**: Easily specify filenames and automatically generate SEO-friendly Alt text. * **Preset Widths**: Choose quick width presets (360px, 540px, 720px, 1080px, 1440px) or upload original dimensions. * **Automatic Block Insertion**: Automatically uploads the processed file to the Media Library and inserts an Image Block into your post. ## Screenshots [⌊Image Paste/Drop Modal dialog prompting for filename, format selection (ORIG/WEBP/ PNG), and width options.⌉⌊Image Paste/Drop Modal dialog prompting for filename, format selection (ORIG/WEBP/PNG), and width options.⌉[ Image Paste/Drop Modal dialog prompting for filename, format selection (ORIG/WEBP/ PNG), and width options.

The image conversion is performed on the client-side (inside your web browser) before the file is uploaded to your WordPress server, saving server memory and CPU resources. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “WebP Image Paster” is open source software.
