PDF Export General Options Dialog Image

Range

Sets the export options for the pages included in the PDF file.

All

Exports all defined print ranges. If no print range is defined, exports the entire document.

Pages

Exports the pages you type in the box.

To export a range of pages, use the format 3-6. To export single pages, use the format 7;9;11. If you want, you can export a combination of page ranges and single pages, by using a format like 3-6;8;10;12.

Selection

Exports the current selection.

View PDF after export

Open the exported document in the system default PDF viewer.

Images

Sets the PDF export options for images inside your document.

Lossless compression

Selects a lossless compression of images. All pixels are preserved.

JPEG compression

Select a JPEG compression level. With a high quality level, almost all pixels are preserved. With a low quality level, some pixels are lost and artifacts are introduced, but file sizes are reduced.

Quality

Enter the quality level for JPEG compression.

Reduce image resolution

Select to resample or down-size the images to a lower number of pixels per inch.

Select the target resolution for the images.

note

EPS images with embedded previews are exported only as previews. EPS images without embedded previews are exported as empty placeholders.


Watermark

Add a centered, vertical, light green watermark text to the page background. The watermark is not part of the source document.

Sign with watermark

Check to enable the watermark signature.

Text

Insert the text for the watermark signature.

note

You cannot adjust the position, orientation and size of the watermark. The watermark is not stored in the source document.


General

Sets general PDF export options.

Hybrid PDF (embed ODF file)

This setting enables you to export the document as a .pdf file containing two file formats: PDF and ODF. In PDF viewers it behaves like a normal .pdf file and it remains fully editable in LibreOffice.

Archival (PDF/A, ISO 19005)

Converts to the PDF/A-1b, PDF/A-2b, or PDF/A-3b format. All fonts used in the source document are embedded in the generated PDF file, and PDF tags are written. The primary purpose is to create an electronic document whose appearance is device and application independent, making it suitable for long term preservation.

note

PDF/A-2b is recommended for most users, because it allows for layers and transparency with shapes and images. It also compresses better (JPEG 2000) than PDF/A-1b, usually producing smaller files. PDF/A-3b is identical to PDF/A-2b, but also accepts embedding of other file formats.


Universal Accessibility (PDF/UA)

Creates a universal accessibility-complying PDF file that follows the requirements of PDF/UA (ISO 14289) specifications.

Tagged PDF (add document structure)

Select to write PDF tags. This can increase file size by huge amounts.

Tagged PDF contains information about the structure of the document contents. This can help to display the document on devices with different screens, and when using screen reader software.

Create PDF form

Choose to create a PDF form. This can be filled out and printed by the user of the PDF document.

Submit format

Select the format of submitting forms from within the PDF file.

Select the format of the data that you will receive from the submitter: FDF (Forms Data Format), PDF, HTML, or XML.

This setting overrides the control's URL property that you set in the document.

Allow duplicate field names

Allows you to use the same field name for multiple fields in the generated PDF file. If disabled, field names will be exported using generated unique names.

Structure

Sets options for diverse features such as outlines, comments, page layout.

Export outlines

Select to export all headings in Writer documents as PDF bookmarks.

note

Only paragraphs with Outline level 1–10 will be exported. The name of the Paragraph Style is irrelevant. For example, the default version of Paragraph Style Title is not exported when its Outline level is None. To see a paragraph’s Outline level, choose Format - Paragraph - Outline & Numbering tab.


Comments as PDF annotations

Select to export comments of Writer and Calc documents as PDF annotations.

Comments in margin

Select to export comments of Writer documents in the margin, as they are displayed in the application. Note that this necessarily scales the page contents down to make the comments fit on the page, for the whole document, regardless of the size of the margins.

Export automatically inserted blank pages

If switched on, automatically inserted blank pages are exported to the PDF file. This is best if you are printing the pdf file double-sided. Example: In a book a chapter paragraph style is set to always start with an odd numbered page. If the previous chapter ends on an odd page, LibreOffice inserts an even numbered blank page. This option controls whether to export that even numbered page or not.

Use reference XObjects

This option affects how PDF images are exported back to PDF. When this option is disabled, then the first page of the PDF data is included in the output. The PDF export merges the used images, fonts and other resources during export. This is a complex operation, but the result can be viewed in various viewers. When the option is enabled, then the reference XObject markup is used: this is a simple operation, but viewers have to support this markup to show vector images. Otherwise a fallback bitmap is shown in the viewer.
