About this plugin
Features | Blog | Get Support ImageCraft is your all-in-one WordPress image optimizer — it handles every image task in one plugin. Compress images without losing quality, convert to WebP & AVIF , fix broken images with fallbacks, generate SEO-optimized alt text and titles with AI, rename files for SEO, and audit your media library health — no need to juggle multiple plugins. Two pillars, one workflow: Image Optimization — smart compression, WebP & AVIF conversion, and image fallbacks, all running 100% locally on your server with no external service. AI Image SEO — alt text, titles, descriptions, and file renaming written automatically using OpenAI, Claude, Gemini, or the WordPress 7.0 native AI Client. Optimize your entire media library in minutes — compress, convert, and generate SEO metadata — all while keeping your pages fast and search-engine friendly. Why ImageCraft? Most plugins do one thing — either compression or alt text — and many charge monthly subscriptions or per-image credits through their own proxy service. ImageCraft does everything in one plugin: compression, WebP/AVIF conversion, and image fallbacks run locally on your server for free, while AI generation connects directly to your provider (you pay only the standard API rate with zero markup). Core Features Smart Image Compression — quality-preserving, runs locally, with one-click restore WebP & AVIF Conversion — next-gen copies served via <picture> , originals untouched PNG → JPG Conversion — convert opaque PNGs to smaller JPGs with transparency detection, backup, and one-click restore HEIC → JPG Conversion — auto-convert iPhone HEIC uploads to JPG so every browser can display them Image Fallbacks — replace broken images for visitors and set a default featured image for posts without one (non-destructive) AI Image Alt Text Generator (SEO optimized) AI Image Title & Description Generator AI-powered File Renamer for better image SEO Image SEO Audit Dashboard with quality scoring SEO keyphrase integration — works with Yoast SEO , Rank Math , AIOSEO , and SEOPress WooCommerce product-aware alt text generation WP-CLI support — manage compression, conversion, alt text, and more from the command line Batch processing for compression, conversion, alt text, and titles with real-time progress Key Features Smart image compression — Reduce image file size with a built-in, quality-preserving compressor that runs locally on your server. Bulk-optimize your library, compress from the media modal, and restore originals anytime. Smaller images mean faster pages and better Core Web Vitals. WebP & AVIF conversion — Generate next-gen copies beside your originals and serve them through a <picture> element. Fully reversible, covers every thumbnail size, and discards any copy larger than the source. PNG → JPG conversion — Convert opaque PNG images to smaller JPGs. ImageCraft detects transparency automatically and skips transparent PNGs. Originals are backed up for one-click restore, and all URLs in your posts are updated. Available as a per-image button, bulk action, or automatic on upload. HEIC → JPG conversion — iPhone and iPad photos upload as HEIC, which most browsers cannot display. ImageCraft auto-converts them to JPG on upload (default on) so they work everywhere. Requires Imagick with HEIC support; a capability badge shows whether your server supports it. Image fallbacks (never show a broken image) — Pick one fallback image and ImageCraft shows it whenever an image on your site fails to load, and as the featured image for posts that don’t have one. It even carries proper alt text, and a broken-image scan on the dashboard tells you which media files are missing. Nothing is written to your content — turn it off and everything reverts. AI alt text, titles & descriptions — Generate all three in a single AI call with 3 providers and 17+ models. Choose from Anthropic Claude, OpenAI, and Google Gemini. Switch providers and models anytime. Gutenberg, Kadence, Spectra & Media Modal integration — Generate alt text with one click from the block editor sidebar, Kadence image block, Spectra image block, or WordPress media modal. Preview, accept, or reject without leaving the editor. Spectra Block support — Full integration with Spectra image block: generate alt text and title directly from the block inspector sidebar. Kadence Blocks support — Full integration with Kadence image block: generate alt text, title attribute, and link title directly from the block inspector sidebar. AI-powered file renaming — AI generates SEO-friendly filenames directly from image content. Independent from alt text and title — each is a separate AI call. SEO keyphrase integration — Pulls the focus keyphrase from Yoast SEO , Rank Math , All in One SEO , or SEOPress and naturally weaves it into generated alt text. FileBird integration — Filter the scanner by FileBird folders and use folder context to generate more specific alt text prompts. Image SEO audit dashboard — Scores your media library health. Detects missing, generic/placeholder, and too-long alt text with a visual breakdown. WooCommerce product awareness — Sends product name, SKU, categories, and price as context. Includes 3 dedicated product tones (SEO, Descriptive, Lifestyle) plus custom prompt support.

Everything runs locally on your server using the image libraries WordPress already uses (Imagick/GD). Visually-lossless compression — strips bloated metadata and optimizes JPG, PNG, GIF, and WebP with no noticeable quality loss Automatic downscaling — oversized images are scaled down to a sensible maximum dimension One-click bulk compression — optimize your whole media library from the dashboard Compress from the media modal — a Compress button right where you manage your images Safe by default — every original is backed up, so you can restore any image with one click Never enlarges — only keeps the result when it is actually smaller than the original Faster pages, better SEO — smaller images improve load time and Core Web Vitals, which Google rewards in search rankings Next-Gen Formats (WebP & AVIF) Modern browsers load WebP and AVIF significantly faster than JPEG or PNG. ImageCraft generates next-gen copies beside your originals and serves them through a standard <picture> element, so supporting browsers get the smaller file and everything else falls back to the original automatically. Nothing is overwritten — your original files, URLs, and media library entries are untouched; the converted copies sit alongside them Fully reversible — remove every generated file in one click and your site is exactly as it was Covers every size — full size plus all the thumbnail sizes WordPress generates Never bigger — if a converted copy would be larger than the source, it is discarded Bulk convert — process your whole media library, with a scan showing what is left Off by default — enable WebP and/or AVIF under Performance → Next-gen Formats when you are ready Pro: automatic conversion on upload Format Conversion (PNG → JPG, HEIC → JPG) Many PNG images are photographs or graphics without transparency — storing them as PNG wastes space. ImageCraft detects whether a PNG uses transparency and converts opaque ones to JPG, often cutting the file size in half. For HEIC images (common from iPhones), ImageCraft auto-converts them to JPG on upload so every browser can display them. Transparency detection — only converts PNGs that have no transparent pixels; transparent PNGs are automatically skipped Backup & restore — originals are backed up and can be restored with one click URL rewriting — all references in your post content are updated to the new filename Never-enlarge guard — if the JPG would be larger than the PNG, the conversion is skipped HEIC auto-convert — enabled by default; converts HEIC/HEIF uploads to JPG automatically Bulk convert — process your whole media library from the Performance screen Capability badge — shows whether your server supports HEIC conversion (requires Imagick with HEIC support) WP-CLI Manage ImageCraft from the command line with wp icais .
