The Privacy-First FreeConvert Alternative
Convert and compress files without uploading them — fast, free and private.
FreeConvert supports many formats, but conversions run on its servers and larger files or faster speeds require a paid plan. Crystal Toolkit focuses on the most common conversions and compressions and runs them locally in your browser, so there is nothing to upload, no queue and no subscription.
