Using FLIP2PDF, you can select the following options for the PDF output in your JSON profile file:
|pdf-output-type||Create a PDF, PDF/A, or PDF/X document.||Microsoft Office: PDF, PDF/A-1
PostScript: PDF, PDF/X-3
|compression||Select either lossy (JPEG) or lossless (Flate/ZIP) compression for images embedded in PostScript or Microsoft Office files, or found on web pages for HTML conversion.||Microsoft Office: jpeg, flate
PostScript: jpeg, flate
HTML: jpeg, flate
|downsample||Downsample images from the input files or preserve the original resolutions for these images.||Microsoft Office: on, off
PostScript: on, off
HTML: on, off
|downsampling-dpi||Set the resolution for downsampling images in dots per inch.||Microsoft Office: 75, 150, 300, 600, 1200
PostScript: 75, 150, 300, 600, 1200
HTML: 75, 150, 300, 600, 1200
|tagged-pdf||Create a tagged PDF document for use in providing accessibility to disabled users.||Microsoft Office: on, off|
|page-size||Select a page size for the PDF file.||HTML: letter, legal, ledger, A3, A4, A5|
|page-margin||Set margins for a PDF file in inches (in) or millimeters (mm).||HTML: “0.75in”, “15mm”|
|page-orientation||Set the page orientation to portrait or landscape.||HTML: portrait, landscape|
|web-layout||For web pages with responsive design, select the web layout intended desktop, tablet, or mobile viewing.||HTML: desktop, tablet, mobile|
PDF/A and PDF/X
For PostScript files, select either PDF or PDF/X as output in the JSON profile.
For Office files, select either PDF or PDF/A (Archive) as output. FLIP2PDF will generate PDF/A-1a files.
Note: FLIP2PDF can generate PDF/A archive files but the software cannot certify that these files satisfy ISO standards for PDF/A conformance.
Lossy or Lossless Compression
Lossy and lossless refer to the approach used for compressing data. For lossless, all of the data in the image is preserved. The quality of the image does not change, and it can be uncompressed to its original state. Lossy compression permanently removes data from the image file, such as pixels, reducing the image resolution. Files reduced using lossy compression will be considerably smaller but will not print or display as well as those compressed using lossless compression.
For lossless compression, you would enter this statement in the JSON profile:
"compression" : "flate"
For lossy, use this value instead:
"compression" : "jpeg"
Downsampling involves reducing the size of a graphic file when generating output. If you know that you do not need high resolution images embedded in a PDF document, you can downsample these images to a lower resolution to reduce the size of the PDF document itself. The downsampling process involves changing the width and height of an image in pixels to reach a given target resolution that FLIP2PDF allows you to select. Target options for downsampling images include 75, 150, 300, 600, and 1200 Dots per Inch (DPI).
FLIP2PDF is set up to downsample images by default, and each one to 300 DPI. If you set the downsample option to “off” the process will preserve the original resolution of each image in the PDF output file. Or you can set downsample to “on” and then select your own target resolution, greater or less than 300 DPI. The software preserves any design or size information found in an image.
Tagged PDF Document
For Microsoft Office files, you can choose to produce a tagged PDF. A tagged PDF document contains metadata to describe instructions related to headers and other content on a page. Tagging is generally used with a PDF document to meet accessibility requirements. For example, tags in a PDF document might be placed so that text, headings, footnotes and other content in the document can be interpreted by a screen reading software tool. The tool could use this information to read text in the document out loud for a blind person or respond to voice commands for a reader who can’t easily use a mouse or keyboard.
Margins, page size, and page orientation
For HTML files and web pages, you can set options to define a margin around the output PDF pages, choose a standard PDF page size, or set those pages to landscape orientation rather than portrait.
Select the web layout for responsive web pages
For web pages designed to be responsive to different device screen sizes, you can choose the layout intended for desktop, tablet, or mobile viewing. This will not affect the size of the output PDF but may result in different layout of the content, depending on whether the HTML input supports responsive design.
