Frequently asked questions

How long does SWF to ASF take?

It runs on your device’s processor. On a computer a one-minute 1080p video usually takes a minute or two; lowering the resolution speeds it up.

Is there a file size limit?

No fixed limit; your device’s memory decides. Computers usually handle files up to 1–2 GB.

Is my file uploaded?

No. Your SWF file is converted to ASF inside your browser.
