Ways to Use Alt Text Generation
Course Module Slides
Upload lecture slide images and diagrams. OPT-IMG creates descriptive alt text and consistent filenames, then outputs 1600px/800px sets so modules load faster on mobile and desktop within your LMS.
Student Portal Accessibility
Standardize alt text for portal announcements, events, and resources. Batch process assets before publishing to ensure accessible descriptions and readable filenames across departments.
Video Thumbnail Catalog
Generate alt text and social variants for video library thumbnails. Smart cropping maintains speaker faces and key graphics across hero, blog, and card sizes.
LMS Course Banners
Prepare banners in correct formats with alt text and responsive sizes. Export OG/Twitter variants to promote new courses without manual re-cropping in design tools.
Research Poster Galleries
Convert high-resolution posters to optimized WebP/AVIF sets with clear, context-rich alt descriptions. Use PRO to remove EXIF data and protect camera or location metadata.
Open Online Courses

Common Education Challenges
Inconsistent Accessibility Across Courses
Faculty and TAs write alt text differently—or skip it under deadlines. OPT-IMG generates descriptive, consistent alt text aligned to content, improving screen reader experiences. Teams can review and edit before download, ensuring higher WCAG-aligned coverage across courses.
Slow LMS Pages from Heavy Images
Large, unoptimized images delay course content, especially on mobile connections. OPT-IMG creates responsive 1600px and 800px sizes in efficient formats, cutting weight without losing clarity. Faster pages keep students engaged and reduce bounce during peak times.
Faculty Naming and Alt Text Chaos
Random filenames and missing descriptions hurt SEO and content findability. OPT-IMG assigns clean, SEO-friendly filenames and accurate alt text, making assets easier to manage, search, and reuse across semesters.
Multi-Platform Image Requirements
Announcements, course catalogs, and social promos all need different dimensions. PRO variants and smart cropping produce perfectly sized assets while preserving focal points, eliminating tedious manual resizing for each channel.
Manual Photoshop and Text Entry Overload
Designers spend hours exporting sizes and typing alt text. OPT-IMG automates analysis, naming, and resizing in batches of 10–10,000, delivering a ZIP with and HTML snippets to paste directly into your LMS.
Privacy and Compliance Risks in Media
Images can contain sensitive EXIF metadata from staff or student devices. OPT-IMG PRO can strip EXIF on export, reducing data exposure while preserving visual quality and accurate descriptions.
