ChangeMyFile

ChangeMyFile started as a file converter and grew into a full toolkit — 50+ free tools covering PDFs (split, merge, compress, highlight), images (crop, resize, passport photos), video, audio and speech-to-text transcription, plus AI tools for background removal, upscaling and photo restoration. Everything runs in the browser with no signup, no account and no watermarks. Heavier jobs run server-side in isolated containers; uploads are deleted within 24 hours and download links expire after an hour. Supports 700+ format pairs, with over a million files processed since 2022. Free to use, kept running by ads rather than a paywall — so there's no "upgrade to export" moment halfway through a conversion.
