Choose your file: Select the audio or video file you want to convert, extract, or compress.
Pick the result you need: Choose MP3, WAV, FLAC, MP4, or a smaller-file preset that matches the job.

Read guideFAQs
Direct answers about no-upload browser conversion, supported tools, file-size limits, mobile support, and choosing the right page.
What can I do on Creaptor right now?
The current tool set covers audio extraction from video, audio conversion, audio compression, video compression, and video-to-MP4 conversion.
What file size works best for local browser processing?
On mobile and low-memory devices, files above 100 MB may be less reliable and files above 200 MB are rejected. Desktop browsers warn above 200 MB and reject files above 500 MB. Completion still depends on available memory, the input codec, and the output job.
How do I choose between similar pages like MP4 to MP3, Video to MP3, and Audio Converter?
Use the most specific page when the source file or target result is already clear. If several pages still look similar, open the route comparison guides before you start.
Do my files upload to a server during conversion or compression?
No. The normal Creaptor workflow is designed to process selected files locally in your browser, so the media file itself does not need to be uploaded to my server.
Does Creaptor work on mobile browsers like iPhone Safari or Android Chrome?
Yes, but mobile browsers are less reliable for larger files and longer jobs. For heavier local processing, a current desktop browser is still the safest option.
Is Creaptor free to use right now?
Yes. The current browser tools are free to use and do not require an account. Creaptor doesn't add watermarks, and it doesn't remove watermarks already present in source files.
