Learn how browser memory, file size, and heavy media engines affect local file conversion.
Browser memory is finite
Local conversion uses memory in the current tab. Very large PDFs, images, audio, and video files can take longer or fail on low-memory devices.
Keep the tab open
Do not close or reload the page while the conversion engine is reading, rendering, transcoding, or packaging the output.
Test important files
For production workflows, test representative file sizes and decide where backend processing is needed.
