FAQ
Common questions about browser-only file conversion.
Are files uploaded to a server?No. Selected files are processed in the browser, and converted results are not stored on a server.
What should I do if processing is slow?Lowering FPS, output size, color count, or processing duration reduces browser memory use and processing time.
Can I use it on mobile?Yes, but desktop browsers are more stable for large files.
