Convert a UTF-8 TXT file without losing your draft

Use the file workflow for a document you want to keep as a TXT file. The editor handles one UTF-8 file at a time, up to 10 MiB. With Pro, a larger file converts directly to a new file: up to 1 GiB on Mac and 100 MiB on iPhone and iPad.

Before importing

Save the document as plain-text .txt in UTF-8. A UTF-8 byte-order mark (BOM) is accepted. The app does not guess Big5, GBK or another encoding. If the file exceeds 10 MiB, use the Pro large-file conversion below, or reduce or split it first.

Import, convert, export

  1. Import one file. Choose Import TXT in the workspace, or drop a single TXT file onto it. A successful import replaces the source text.
  2. Choose a preset and convert. Read the source and result together; a new file is not saved automatically.
  3. Choose Export TXT. The app exports the latest successful result as UTF-8 without a BOM. For example, essay.txt suggests essay-converted.txt; choose the save location in the system panel.

If something goes wrong

An oversized or invalidly encoded import keeps the previous draft. A failed or canceled conversion does not replace the last successful result. The file flow preserves line endings, blank lines, Emoji, combining characters and embedded U+0000; still inspect the converted words before sharing the document.

Larger files with Pro

With Pro, choose Import TXT and pick one UTF-8 TXT file larger than 10 MiB. On Mac it can be up to 1 GiB; on iPhone and iPad, up to 100 MiB. The file is converted directly to a new file and you choose where to save it. Its text does not enter the editor, so the current draft and result stay in place, and homepage conversions are not used. The task shows progress and can be canceled.

On iPhone and iPad, keep the app open while it converts: moving to the background or locking the device stops the task safely. A finished result is kept until you save or delete it, even after an app restart. Drag and drop on iPhone and iPad stays limited to 10 MiB. Batch conversion is not supported.
