Frequently asked
Yes. Compression is free with no signup. Shorty Premium lifts the per-file size cap and unlocks the highest-quality (visually lossless) presets.
No. The output keeps the same format as your source — a compressed MP4 stays an MP4, a compressed PNG stays a PNG. If you need a different format, use the main File Converter.
Device mode runs locally in your browser — private and fast for smaller files. Cloud mode sends the job to our servers and gives you better compression with GPU-class encoders. Both are free.
It depends on the content. Aggressive presets can shrink video to 20% of the original, images to ~50%, and audio to ~25%. Pick "Balanced" for a sensible default with no visible loss.
