Before you start: Confirm these points first

Take a minute to confirm the following items before taking action to avoid detours.

Confirm that the document is indeed a scanned copy. Open the PDF, press and hold a piece of text with your finger to try to select it. If you cannot select it, or the entire page is just a picture, it is basically a scanned copy. Scanned documents can be directly uploaded for translation without the need for separate text recognition first.
Confirm that the mobile phone network is stable. If you disconnect from the Internet, switch applications, or lock the screen for a long time when uploading files, the upload may be interrupted and you need to start over. This is especially important for documents with a large number of pages.
Place the files in an easy-to-find location in advance. In the file management of your phone, put the PDF you want to translate into "Downloads" or a fixed folder. Selecting from a file list when uploading is faster than searching all over the place.
Think clearly about what the translation is used for. If you want to just read, choose the translation only; if you want to compare it with the original paragraph by paragraph, choose bilingual comparison. The output method determines the workload of subsequent verification, so decide it before taking action.
Be aware of the sensitivity of the document content. For documents such as contracts, medical records, identity materials, etc., please confirm that the content can be handed over to the online service for processing before uploading. Don't work on other people's phones or public networks.

Steps to translate and scan PDF in mobile browser

Enter omnidoc.top in the address bar of your mobile browser and open it. Commonly used mobile browsers are sufficient, and there is no need to install a separate application.
Enter the document translation function and select upload. Click the upload portal and select the scanned PDF to be translated from the mobile files.
Wait for the file upload to complete. The larger the file, the longer it will take to upload. Stay connected to the Internet during the upload, and do not close the page or switch to other applications.
Select the output method. Based on the previous table, select bilingual comparison or translation only.
Select a document type or style (if provided on the page). Select academic, legal, medical, technical, business or literary styles according to the nature of the article to help the terminology fit more closely with the original text.
Start translation and wait for completion. The text in the scanned document needs to be recognized first and then translated. If there are many pages, you need to wait a little longer and the page will be displayed before downloading.
Download the translation. Click to download and the file will be saved to the download location on your phone. It can then be opened, viewed, or forwarded to others using file management apps on your phone.

Check each item after completion

Do not use the translated text directly after downloading it, especially formal materials such as contracts, documents, papers, etc. The following check items can help you quickly determine whether the results are reliable.

Check items	How to see	What to do if there is a problem
Are the number of pages complete?	Compare the original scanned copy, turn to the last page, and confirm that the page numbers are consistent.	If the number of pages is insufficient, re-upload it and check whether the original file is complete.
Layout and forms	Check whether the position of the table, picture and formula is the same as the original	When the position is confused, compare it with the bilingual control version first; when the original is blurred, change to a clear scan and re-translate it.
Number, date, amount, name of person	Compare with the original item by item, especially the key value	Machine translation may make mistakes, and the important contents must be checked manually. If necessary, please confirm it by a professional.
Whether the professional terms are unified or not	When the same term appears many times, see if the translation is consistent.	Select the corresponding document style to re-translate, or download and modify it on the computer.
Identification of blurred scanning	Find the light color, stain or blurred handwriting of the original, and compare the translation.	This kind of location is easy to identify errors and re-upload it with a clearer original.
