Frequently asked questions
How do I convert TXT to DOCX?
Add your TXT files above, make sure DOCX is selected and press Convert. The DOCX files are ready to download a few seconds later — no installation or account required.
Is there a file size or daily limit?
No. Since everything runs locally, there are no daily caps, queues or file size limits beyond what your device can handle.
Are my TXT files uploaded to a server?
No. ConvertMathly converts files entirely inside your web browser using JavaScript and WebAssembly. Your files never leave your computer or phone, which makes it safe for private photos and documents.
Can I convert multiple TXT files at once?
Yes — add as many files as you like. They are converted one after another and you can download everything in a single ZIP.
Does it work with scanned PDFs?
The converter rebuilds text, headings and paragraphs from PDFs that contain selectable text. Scanned PDFs are images of text, so they need OCR software first.
