Which free mobile document software is the best? One sentence conclusion

To put it simply: for editing short Word documents, viewing PDFs, and doing basic translations, web tools on mobile phones are basically enough; for long-form typesetting, finalizing complex tables and formulas, it is recommended to go back to the computer to complete them.

your situation	Recommended practices	reason
Received .docx file, only changed a few words	Open it with a web page editor that supports Word format and download it after modification.	The file size is small, changes are concentrated, and can be completed on a mobile phone
I have an English PDF in hand, and I want to understand the main idea.	Upload in the web version of the translation tool and select translation only or bilingual comparison.	No need to change the original text, the translation can be read on your mobile phone
Scanned PDF, copy text from it	First use a tool with OCR function to identify, and then check it section by section.	The text in the scanned document is an image and cannot be selected directly. You need to check for typos after recognition.
A paper or long contract of more than thirty pages	Read and comment on the mobile phone, and finally modify it back to the computer	The screen is small, page turning and front-to-back comparison are inefficient, and it is easy to miss views.
Document contains confidential or sensitive content	Read the terms of service first and confirm that the upload is acceptable; if the upload cannot be done, return it to your computer for local processing.	When uploaded to an online tool, the file must go through the other party’s service.

What are the different methods?

The file management function that comes with the mobile phone

Most mobile phones can directly preview common Word, PDF and table files without having to install anything else. It's great for viewing, forwarding, and quick flipping. The shortcoming is that editing capabilities are usually very limited, complex formats are easily misaligned after opening, and changes are difficult to control accurately. If you just want to glance at the content, this is enough.

Online conversion website

The process for this type of site is straightforward: upload the file, select the target format, and download the converted result. It is suitable for single-step needs such as converting Word to PDF and converting PDF to images. The shortcoming is that the layout may change after conversion, and tables, formulas and pagination are prone to problems. Before using it, pay attention to the file size limit, whether to add a watermark, and how long the original file will be retained after conversion.

browser translation plug-in

Many mobile browsers have limited support for plug-ins, and whether they can be used depends on the browser itself. The web translation plug-ins that are common on the desktop may not be installed on mobile phones. In this case, don't look for it. It's easier to open a web tool instead.

online editor for web version

The UniDoc Page Editor (app.unidoc.top) supports Word-compatible editing, opens and modifies .docx documents, supports formulas, and converts between Word and LaTeX. It is suitable for such needs as changing the terms of the contract, amending the text, supplementary paragraphs and so on. The short board is that when the document structure is complex, you still have to check the paging and format after correcting, and do not default to exactly the same typesetting.

OmniDoc web version

OmniDoc currently provides web version (omnidoc.top) and desktop client, there is no dedicated mobile phone App. Open the web version in the mobile browser, you can upload PDF, Word and other files, choose bilingual control or only translation, download the results. It is suitable for reading foreign documents, understand the main idea before deciding how to deal with it. The deficiency is that it is not convenient to compare the original text with the translation on the mobile phone, and the machine translation results need to be checked. Whether it is fully available on your phone and browser, it is recommended to try it with a small file first.
