Runs entirely on your device — forever free

Convert anything
into exactly what you need

Images, HEIC, Office files, PDFs, data, audio and video — plus exact-KB compression, OCR and transcription. No uploads, no ads, no limits.

Drop a file — we'll tell you what it actually is

We read the real bytes, not the file name, then show only the conversions worth doing for this exact file: size, speed on your device, and what gets lost.

…or drag it here, or paste a screenshot. Nothing is uploaded.
