Frequently asked questions
Everything you need to know about AltFrame.
What is alt text and why does it matter?
Alt text (alternative text) is an HTML attribute that describes an image for screen readers and search engines. It improves web accessibility for visually impaired users and is a key on-page SEO signal — images without good alt text are invisible to Google.
How does AltFrame help with accessibility compliance?
AltFrame generates descriptive, meaningful alt text that follows WCAG 2.1 guidelines. Every description is tuned for screen reader compatibility, helping you meet Section 508, ADA, and EN 301 549 requirements.
Can I use the API in a production pipeline?
Absolutely. All plans include REST API access authenticated with an API key. You can integrate alt text generation into your CMS, CDN upload hook, or build process. Bulk endpoints support up to 100 images per request with optional webhook callbacks.
How is pricing calculated?
Each standard image processed costs 1 credit. Advanced formats (AVIF, HEIC, TIFF) cost 2 credits. Additional language translations each cost 1 extra credit. Unused credits roll over each month on paid plans.
Is there a free trial or money-back guarantee?
The Free plan includes 50 credits every month — no credit card required. Paid plans come with a 14-day money-back guarantee if you're not satisfied.
