Automate thumbnails with intelligent alt text, filenames, and responsive sizes
Turn your thumbnails, channel art, and promos into accessible, searchable assets with intelligent alt text, SEO filenames, and optimized formats—automated processing that preserves focal points and accelerates every upload across platforms.
PRO variants and smart cropping for every platform, format, and ratio
Generate five platform-ready variants—Open Graph 1200×630, Twitter Card 1200×675, Hero 1920×1080, Blog 400×225, Product Square 1200×1200. Smart cropping preserves faces and key subjects across aspect ratios. Batch 10–10,000 images in a queue, then export as WebP, AVIF, JPEG, or PNG with a file list and HTML snippets.
Ways to Use Alt Text Generation
YouTube Thumbnail Library
Create consistent filenames and alt text for thumbnails stored in your CMS or media page. Export responsive sizes for fast embeds on your website and blog recaps, then upload the chosen thumbnail to YouTube manually.
Twitch Panels & Overlays
Describe panels and overlays with precise alt text for accessibility on your site or channel companion pages. Smart cropping preserves streamer faces and logos when generating platform-friendly ratios.
Social Promo Posts
Generate descriptive text for platforms that support image alt text (e.g., Instagram and X). Export Open Graph and Twitter Card variants to ensure accurate link previews when sharing episodes or VODs.
Episode Blog Recaps
Batch process episode stills, add meaningful alt text, and export optimized images with HTML snippets. Paste the snippets into your CMS to speed publishing and improve search visibility.
Channel Store Graphics
Produce square product images for merch with consistent alt text and filenames. Export crisp WebP or AVIF to reduce weight and keep product tiles snappy on landing pages.
Press Kit & Media Page
Build a media kit with labeled headshots, logos, and banners. Alt text, filenames, and a file list help journalists and partners quickly find and cite the correct assets.
Common Streaming & Content Challenges
Platform-Specific Image Requirements
Creators juggle different sizes, ratios, and file limits across YouTube, Twitch, and social platforms. OPT-IMG generates responsive sizes and PRO variants, with smart cropping to maintain focal points. You upload the right version for each platform, confident it will look correct everywhere.

Writing clear, descriptive alt text for every thumbnail, panel, and promo takes hours. Automated generation creates accurate, readable descriptions in seconds. Export HTML snippets so alt attributes are ready to paste into blogs, landing pages, and CMS media fields.
Inconsistent Naming Hurts Search
Unstructured filenames like “thumb_final_final2.png” weaken discoverability. OPT-IMG creates SEO-friendly filenames aligned to your content topics and episodes, improving media library organization and helping search engines understand your images on your site.

Heavy images inflate load times on episode pages and archives, hurting clicks to watch. Convert to modern formats (WebP/AVIF) with responsive 1600px and 800px sizes to cut weight while preserving sharp text and logos.
Scaling Batches for Release Schedules
