Compress a file before sending
With a premium subscription, you can compress files to reduce their size. Compressed files consume less bandwidth and are easier and faster to work with. Note that you cannot compress files that have been previously compressed.
To compress a PDF file:
Tap > Compress PDF.
In the compress dialog that opens, select a compression level and tap “Compress”. It displays a message saying the compression is in process.
Once your PDF is compressed, a confirmation message is displayed. To open the compressed file, tap Open.
The compressed file is named as ‘filename_compressed.pdf’ and is saved to Adobe cloud storage.
Subscribers to Adobe Acrobat Premium or Adobe Acrobat Pro DC can protect PDFs by setting a password. It can help you secure confidential information and restrict unauthorized access.
Setting a password for a file creates a password-protected copy of the file. It doesn’t protect or change the original file.
To set a password for a PDF file:
Tap the > Set password.
In the dialog that opens, enter a password and then confirm it.
Tap Set password.
You see a message confirming that a password-protected copy is being created.
Once done, a confirmation message is displayed, as shown below. It creates a file copy named “<filename>_protected.pdf” and saves the file to Adobe cloud storage.
To open a password-protected PDF file:
From the confirmation message, tap Open.
Else, from the list of files, tap the password-protected filename to open it.
In the dialog that opens, enter the password and tap OK.
Note the following limitations in password-protected PDFs:
You cannot edit, fill & sign, compress, or export password-protected PDFs.
You can remove the password with desktop Acrobat if you know the original password.
There is no separate password for edit. If a user can open a file, they can edit the file.
Currently, Acrobat Reader mobile app does not support printing of password-protected PDFs.
Share a file
You can send a document to others by sharing the file link through 3rd party apps. Sharing a file via link allows you to send a shared file to more recipients. Sharing via link saves bandwidth and provides access to files stored in the cloud. To share a file:
From the list of files, tap next to the file.
Alternatively, open the file and tap from the top menu.
From the dialog that opens, take any of the following options:
From the list of available 3rd party apps, select any app and follow through the steps. The file link is automatically created and shared via the selected app.
Tap Get link and once the link is copied on your clipboard, paste and send it via email, message, or other supported apps.
Recipients of links shared by owners are not added to the People list of shared documents. The link recipients also cannot access the shared document from the ‘Shared by others’ list in the Adobe cloud storage.
With a subscription to Adobe Acrobat Premium or Adobe Acrobat Pro, you can export unshared PDF files to various different formats:
Document formats: DOCX, DOC, RTF, XLSX, and PPTX
Image formats: JPEG and PNG
When exporting PDFs to document formats, Acrobat supports optical character recognition (OCR) which can convert scanned text into actual text. Acrobat supports many export languages, but OCR recognition is not applicable to export to image formats.

In the Export PDF page that opens, select Document or Image as the export option, as required.

To change the language, tap the selected language and select a different language. By default, the export language is the same as your installed app. Acrobat app supports many export languages.
