Format Master Studio
Read full descriptionHide full description
Format Master Studio brings practical tools for video, audio, images, and PDFs into one clean workspace. VIDEO Convert common video formats and choose the resolution, frame rate, and quality that fit your destination. You can also reverse clips, change playback speed, create GIFs, and extract audio. AUDIO Convert audio formats with control over sample rate, bitrate, and channels. Compress large recordings and export audio as MP3 at 192 or 320 kbps, or as uncompressed WAV PCM; this changes the encoding only and does not improve the source quality. You can also separate vocals and accompaniment or turn speech into editable text. IMAGES & PDF Convert and compress images, stitch pictures together, build a GIF, split a GIF into frames, combine images into a PDF, or export PDF pages as images. TEXT TO SPEECH Turn written content into clear spoken audio for videos, lessons, presentations, and announcements. FILES IN ONE PLACE Receive shared files, browse completed results by type, preview them, and share them from one organized library. The 7-day, 30-day, and 365-day passes are one-time purchases that grant a fixed number of membership days; they do not renew automatically. Lifetime Access is a one-time non-consumable purchase.
