Keep it up!" > > Jason (March 12, 2026) > "This is a clever idea, especially in concert with programmatic (AI-generated) SEO." > > Ryan Hoover, Creator of ProductHunt (17 January 2024) > "We were looking for tools to help our users create and edit images with templates. We tried options like Canva, but Templated.io turned out to be the perfect choice for our product. It offers an easy API to render images, and its embed editor lets us provide our users with a full editing experience without having to create complex frontend components. It's a really great tool!" > > Harish (September 16, 2025) > "We integrate Templated.io into our portal for custom flyer generation. The editor is amazing, and the Canva import tool is exactly what we were looking for. Massive shoutout to Pedro for the technical support. He responds incredibly fast and fixes issues in no time. Highly recommended!" > > Yuan Zhuang (June 9, 2026) > "Brilliant piece of software. Reasonably priced (vs Canva's outrageously expensive API), and despite a few intricacies with the editor, a really fully-featured document generation API. Really great support too from Pedro, the founder!" > > Jacob Burns (August 17, 2025) > "Very reliable platform. Almost no errors ever. Easy to setup templates and use the API. And AMAZING support!" > > Lawrence Perera (March 24, 2026) > "We booked the "Scale" package to use it as a "print product editor" and we are amazed by the features and the support! Pedro replies to every question and also implemented small hints to the API for better functions on our request. Absolutly great Software and Service!" > > Sven Rißmann, südheide.media (December 18, 2025) > "Templated.io is basically a an API-first graphics content designer which makes it super easy to programmatically create document and image assets. It has most basic features and it is robust and "just works". The Make.com app really makes it super simple to incorporate into automation workflows. What sets templated.io apart the most is Pedro and his super fast and service minded, solutions oriented responses." > > Siavash (May 26, 2025) > "Amazing API, perfect support and a lot of new features on a monthly basis." > > Kalina Staykova (November 26, 2025) > "Currently working through an implementation of Templated.io and the customer service has been spectacular!!!

Yes, completely free with no limits or watermarks. Your videos are processed entirely in your browser using FFmpeg.wasm — nothing is uploaded to any server. ### What formats are supported? You can convert between MP4, WebM, AVI, MOV, and MKV. Upload any of these formats and convert to MP4, WebM, AVI, or MOV as output. ### Which format should I choose? MP4 is the best all-around choice for maximum compatibility across devices and platforms. WebM is ideal for web embedding with smaller file sizes. MOV is preferred for Apple devices and professional editing workflows. AVI is useful for legacy software compatibility. ### Will I lose quality during conversion? Some quality loss is inherent when re-encoding video. Select "High" quality to minimize this. The tool uses H.264 (for MP4, AVI, MOV) and VP9 (for WebM) codecs with configurable CRF values to give you control over the quality-to-size trade-off. ### Are my videos uploaded to a server? No. This tool runs 100% in your browser using FFmpeg.wasm (WebAssembly). Your video files never leave your device, ensuring complete privacy and security. ### What is the maximum file size? The tool accepts videos up to 500MB. Since all processing happens in your browser, larger files may take longer to convert depending on your device's capabilities and available memory. ### How long does conversion take? Conversion time depends on the video length, resolution, and your device's processing power. A typical 1-minute 1080p video takes around 30-90 seconds. Browser-based conversion is slower than native desktop software but requires no installation. ### Can I convert MOV to MP4? Yes. Simply upload your MOV file, select MP4 as the output format, choose your desired quality level, and click "Convert Video." The converted MP4 file will be ready to download. ### Does it preserve audio? Yes, audio is preserved during conversion. The tool uses AAC audio encoding for MP4, AVI, and MOV formats, and Opus for WebM — all at 128kbps for clear, high-quality audio. ### What is the difference between MP4 and WebM? MP4 uses H.264 video and AAC audio codecs with near-universal device support. WebM uses VP9 video and Opus audio codecs, offering better compression for web use but with slightly less device compatibility. MP4 is better for sharing and playback; WebM is better for embedding on websites.
