You can salve your changes to an Adobe PDF or PDF Portfolio in the original PDF or in a copy of the PDF. You can also save private PDFs to other file formats, including text, XML, HTML, and Microsoft Word. Saving a PDF in text format allows y'all to apply the content with a screen reader, screen magnifier, or other assistive engineering science.

If you don't have access to the source files that created an Adobe PDF, you can yet copy images and text from the PDF to use elsewhere. Y'all can as well export the PDF to a reusable format, or export images in a PDF to another format.

Adobe Acrobat Reader users can salve a re-create of a PDF or PDF Portfolio if the creator of the document has enabled usage rights. If a document has additional or restricted usage rights, the document message bar under the toolbar area describes the assigned restrictions or privileges.

Save a PDF

Apply this method to save PDFs, including PDF Portfolios, and PDFs in which you have added comments, form field entries, and digital signatures.

Saving a digitally signed PDF invalidates the signature.

To relieve changes to the electric current file, choose File > Salve.
To save a copy of a PDF, choose File > Save As.
In Acrobat Reader, choose File > Relieve As or File > Salve Equally Other > Text.
To relieve a copy of a PDF Portfolio, choose File >Save Every bit Other > PDF Portfolio.

If y'all are viewing a PDF in a web browser, the Acrobat File menu is not available. Utilize the Relieve A Copy button in the Acrobat toolbar to save the PDF.

Recover the final saved version

Choose File > Revert, then click Revert.

About the Autosave feature

The Autosave feature guards confronting losing your work in case of a power failure past incrementally, and at regular intervals, saving file changes to a specified location. The original file is non modified. Instead, Acrobat creates an autosave file of changes, which includes all the changes you made to the open file since the last automatic salvage. The amount of new information that the autosave file contains depends on how frequently Acrobat saves the autosave file. If you lot fix the autosave interval to xv minutes, yous could lose the final 14 minutes of your work if a problem occurs. Frequent automatic saving prevents loss of data, and is particularly useful if you make all-encompassing changes to a document, such as by adding comments.

You can use autosave changes to the original files when you restart Acrobat. When yous close, save manually, or revert to the last-saved version of a file, the autosave file is deleted.

If you use assistive technology, such as a screen reader, you may desire to disable the Autosave feature and then that you don't lose your identify when the file is reloaded.

The Autosave feature won't work in the post-obit cases:

A document that has its security inverse. You must salve the document to re-enable automatic saving of document changes.
A document created using the Spider web Capture characteristic or extracted from a larger PDF (Tools > Organize Pages > Extract). You must save the document to enable automatic saving of changes.
A document displayed in a web browser or incorporated into a container document that supports Object Linking and Embedding (OLE). This document appears exterior the default file organization and cannot support automated saving.

Recover lost changes

To prevent lost changes after an unexpected intermission, enable the Autosave characteristic, which is the default setting.

Prepare automated saving

In the Preferences dialog box under Categories, select Documents.

Select Automatically Save Certificate Changes To Temporary File Every xx Minutes (one-99), and specify the number of minutes.

Recover lost changes after an unexpected shutdown

Start Acrobat or open the file you were working on last.

When prompted, click Yes to open up the autosave file or files. If multiple files were open, Acrobat opens all of the files for you.

Save the file or files with the same names as the files y'all were originally working on.

Reduce file size past saving

You can sometimes reduce the file size of a PDF merely by using the File > Reduce File Size, or File > Salve Equally Other command. Reducing the size of PDFs improves their performance—particularly when they're being opened on the spider web—without altering their appearance.

The Reduce File Size command resamples and recompresses images, removes embedded Base-14 fonts, and subset-embeds fonts that were left embedded. It too compresses document construction and cleans up elements such as invalid bookmarks. If the file size is already as small-scale as possible, this control has no effect.

Reducing the file size of a digitally signed certificate removes the signature.

Open a PDF in Acrobat DC.

Choose File > Reduce File Size or Compress PDF.

Adobe is testing the simplified optimize PDF feel with two different names -Reduce File Size orShrink PDF. Therefore, after updating to the latest release, you see either the Compress PDF option or the Reduce File Size option. From the functionality perspective, both the options are the aforementioned.

Choose the location to save the file and click Salvage. Acrobat DC displays a message showing the successful reduction in PDF size.

Reduce file size successful message

Open a single PDF, or select one or more PDFs in a PDF Portfolio.

Choose File > Save Every bit Other > Reduced Size PDF .

Select the version compatibility that you need.

If you're certain that all your users use Acrobat or Adobe Acrobat Reader, limiting compatibility to the latest version can further reduce file size.

(Optional) To apply the same settings to multiple files, click Utilise To Multiple, and add together the files. Click OK, then in the Output Options dialog box, specify your binder and filename preferences.

The Apply To Multiple push button is not available in PDF Portfolios.

To command changes and quality trade-offs, use PDF Optimizer in Acrobat Pro, which makes more options available.
