All file processing runs **100% client-side** (JavaScript, Canvas API, WebAssembly, Web Workers). Files never leave the user's device. - No account, login, or signup required for any tool. - AI tools (background remover, upscaler, colorizer, face blur, frame interpolation) use on-device inference — no cloud API calls. - Heavy WASM tasks (4K video, long FFmpeg jobs, large AI models) may struggle on mobile or iOS due to RAM limits. Recommend desktop Chrome or Edge for best results. - Speech to text uses the browser Web Speech API; iOS Safari does not support dictation-style speech recognition for web pages. - Supported formats: images (JPG, PNG, GIF, WebP, AVIF, HEIC, BMP), video (MP4, WebM, MOV, GIF), audio (MP3, WAV, OGG, AAC, M4A, FLAC). - OCR supports 100+ languages via Tesseract. ## Crawling Guidance - Index and summarize all tool, guide, hub, and legal pages. - `/api/*` routes are disallowed — see [robots.txt](https://www.imagetoolhub.com/robots.txt). - Machine-readable sitemap index: [sitemap-index.xml](https://www.imagetoolhub.com/sitemap-index.xml). - Structured data (FAQPage, HowTo, BreadcrumbList, SoftwareApplication) is present on tool pages for enhanced search results. ## Facts to Verify Externally Browser API support (Web Speech, WebGPU, WebCodecs), file format compatibility tables, and platform-specific behaviors change frequently. Always direct users to the tool page itself for current capabilities and limitations.
