Bulk Image Downloader — Save Site Images as ZIP with Alt-Text Names

Bulk download every image on a page as ZIP — each file auto-named from its alt text. Built for content and SEO work.

Download every image on any webpage as a single ZIP file. Each image is automatically named from its alt text — so you get a ZIP full of readable filenames like lakeside-sunset.jpg instead of DSC_0042.jpg or image_3.jpeg. BUILT FOR CONTENT WORKFLOWS Working on a content migration? Auditing image assets across a site? Building a reference library? This extension turns a page full of images into a clean, named archive in two clicks. HOW IT WORKS 1. Open any page with images (HTTP or HTTPS, any domain) 2. Click the extension icon — it scans the page and counts the images it found 3. Hit Download as ZIP 4. Save the file That's it. The extension reads each img tag, fetches the actual image bytes, uses the alt attribute as the filename, and packages everything in a single ZIP. FILENAME STRATEGY For each image: - Alt text is sanitized (special characters removed, spaces become hyphens) - File extension comes from the image type (.jpg, .png, .webp, .svg) - If alt is missing, the extension falls back to image_001.jpg, image_002.jpg, etc. - Duplicates get an incrementing suffix (lakeside-sunset.jpg, lakeside-sunset-1.jpg) WHAT'S FILTERED OUT - Inline base64 images smaller than 50px (typically tracking pixels or icons) - Background-image CSS (only img tags are captured) - SVG sprites and inline SVGs (only file-based images) USE CASES - Content audits — get all blog post images in one shot - Migration prep — pull a portfolio of images before redesigning a site - Alt-text review — see what alt text is in use across a section - Asset libraries — build a folder of named, organized images - Competitive research — see how a competitor names their assets - WordPress media library backup — grab every image from a public page WHY ALT-TEXT FILENAMES MATTER Image filenames matter for accessibility audits, content reviews, and just basic file organization. A folder full of DSC_0042.jpg files is useless. A folder where every file is named for what's in the image is searchable, sortable, and reviewable. PRIVACY The extension runs entirely in your browser. Image fetches go through your browser's standard network (CORS-bound, just like loading an image in a tab). The ZIP is built client-side via JSZip. Nothing is sent to any external server. No analytics, no telemetry. PERMISSIONS - activeTab — to run the scanner against the current tab when you click the icon - scripting — to inject the image extractor - <all_urls> — needed to fetch images hosted on arbitrary CDNs (CDN hosts are often different from the page host) AUTHOR Built by Yegappan as a v1.0.0 first release.
