Frequently asked
Yes. Converting MP4 to MP3 is free. Device processing runs in your browser with no account needed; Cloud processing (better encoders, queue tracking) is also free with a quick signup. Shorty Premium unlocks larger file sizes and bigger batch limits for high-volume workflows.
Yes. Each uploaded file gets its own queue card with independent format, quality, and processing controls. You can convert the entire batch at once or start individual items in any order.
Available controls depend on the file type. Audio and video files expose bitrate and trim options. Image files include quality and resolution scaling. PDF conversions include page range and render quality settings where applicable.
Device processing runs conversions locally in your browser — ideal for quick jobs, privacy-sensitive files, and works without an account. Cloud processing queues the job on Shorty's servers and keeps outputs ready to download — free with a quick signup (no card). Premium lifts the file-size and batch caps on top of either mode.
