Why ConvertME

Conversions that stay in the tab.

The conversion engine runs on your device using browser APIs and locally loaded WebAssembly tools. Your selected files are not sent to ConvertME.

Private by design

Your files never leave your device. Conversion happens locally using browser APIs — no data is ever sent to ConvertME.

Supports your formats

JPG, PNG, WebP, HEIC, PDF, DOCX, MP4, MP3, CSV, JSON and more — covered by Canvas, WebAssembly and proven parsers.

No accounts needed

Open a converter, drop a file, download the result. No sign-up, no email, no watermark added to your output.

One page per format pair

Every conversion has a focused page with clear guidance on what to select and what to expect in the downloaded file.

FAQ

Questions, answered.

Are my files uploaded?

No. ConvertME processes selected files locally in your browser. Some advanced converters download processing libraries when first opened, but your document remains on your device.

Is ConvertME free?

Yes. Tools are free to use, require no account and add no watermark to your exported file.

Which conversions work offline?

Converters that are already loaded can work without uploading files. OCR and media conversion may need to download their processing engine or language data on first use.

Can I add another language?

The application uses locale-based routes and dictionaries. Additional translated dictionaries and locale entries can be added without changing tool URLs or conversion logic.

What can ConvertME convert?

ConvertME is a free online file converter that runs entirely in your browser. No files are uploaded to any server — conversion happens locally on your device using WebAssembly and native browser APIs.
