Acrobat reduces the size of a PDF file without compromising quality. The Acrobat PDF compression tool balances an optimized file size against the expected quality of images, fonts, and other file content. PDF Optimizer provides many settings for reducing the size of PDF files. Some of the PDF Optimizer settings are comparable to the settings that are available when you create a PDF file using Distiller.
Whether you use all of these settings or only a few depends on how you intend to use the files and on the essential properties a file must have. In most cases, the default settings are appropriate for maximum efficiency—saving space by removing embedded fonts, compressing images, and removing items from the file that are no longer needed.
The space audit results may give you ideas about where best to reduce file size. You can also reduce the size of your PDF by using the Reduce File Size command. Auditing the space usage gives you a report of the total number of bytes used for specific document elements, including fonts, images, bookmarks, forms, named destinations, and comments, as well as the total file size.
The results are reported both in bytes and as a percentage of the total file size. The PDF Optimizer dialog box opens. You can also audit space usage of a PDF in the Content pane. From the Content pane options menu , choose Audit Space Usage.
Adobe is testing the simplified optimize PDF experience with two different names – Reduce File Size or Compress 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 same. Choose the location to save the file and click Save. Acrobat DC displays a message showing the successful reduction in PDF size. In the toolbar, from the Reduce File Size drop-down list, click Reduce Multiple Files.
Adobe is testing the reduce file size experience in the Optimize PDF toolbar under two different names – Reduce File Size or Compress PDF.
In the Add Files dialog, select the files you want to add and click Open , and then click OK. Select the version compatibility that you need, and click OK. In the Output Options dialog box, specify your folder and filename preferences, and click OK. To use the default settings, choose Standard from the Settings menu, and then skip to step 6.
If you change any settings in the PDF Optimizer dialog box, the Settings menu automatically switches to Custom. From the Make Compatible With menu, choose Retain Existing to keep the current PDF version, or choose an Acrobat version.
The options available in panels vary depending on this choice. Select the check box next to a panel for example, Images, Fonts, Transparency , and then select options in that panel. To prevent all of the options in a panel from executing during optimization, deselect the check box for that panel. Optional To save your customized settings, click Save and name the settings. To delete a saved setting, choose it in the Settings menu and click Delete.
In the Save Optimized As dialog box, click Save to overwrite the original PDF with the optimized PDF, or select a new name or location. Use the options from the panels in the PDF Optimizer dialog box to reduce the size of a PDF. The Images panel of the PDF Optimizer lets you set options for color, grayscale, and monochrome image compression, and image downsampling. Reduces file size by lowering the resolution of images, which involves merging the colors of original pixels into larger pixels.
Note : Masked images and images with a size less than by pixels are not downsampled. Reduces file size by eliminating unnecessary pixel data. In general, JPEG and JPEG compressions give better results on images like photographs with gradual transitions from color to color.
ZIP is the better choice for illustrations with large areas of solid, flat color, or patterns made up of flat colors. For monochrome images, JBIG2 compression, which is available in PDF Optimizer but not in Distiller, and it is superior to CCITT.
Available only for JPEG and JPEG formats. JPEG and JPEG compression methods are typically lossy , a process that permanently removes some pixel data. You can apply lossy JPEG or JPEG compression to color images at various levels Minimum, Low, Medium, High, Maximum. For JPEG compression, you can also specify lossless so that no pixel data is removed.
Compression for monochrome images is lossless, except for JBIG2 compression, which provides both Lossy and Lossless modes of compression. Available only for JPEG format. Divides the image being compressed into tiles of the given size. If the image height or width is not an even multiple of the tile size, partial tiles are used on the edges.
Image data for each tile is individually compressed and can be individually decompressed. The default value of is recommended. Optimize Images Only If There Is A Reduction In Size. When selected, if the image setting will cause an increase in file size, the optimization for that image is skipped. Text in these languages is replaced with a substitution font when viewed on a system that does not have the original fonts. The Fonts panel of the PDF Optimizer contains two lists for fonts: fonts that are available for unembedding, and fonts to unembed.
To unembed fonts in a document, select one or more fonts in the Embedded Fonts list, and click the Unembed button. To prevent unembedding for all fonts in the document, select Do Not Unembed Any Font. If your PDF includes artwork that contains transparency, you can use presets in the Transparency panel of PDF Optimizer to flatten transparency and reduce file size. Flattening incorporates transparency into corresponding artwork by sectioning it into vector-based areas and rasterized areas.
PDF Optimizer applies transparency options to all pages in the document before applying other optimization options. If you select the Acrobat 4. This ensures compatibility with Acrobat 4. When you create flattening presets, they appear with the default presets in the Transparency panel. The Discard Objects panel lets you specify objects to remove from the PDF and lets you optimize curved lines in CAD drawings. You can discard objects created in Acrobat and in other applications. Selecting an object removes all occurrences of that object within the PDF.
In the Discard Objects area, you can select from these and other options:. Discard All Form Submission, Import And Reset Actions. Disables all actions related to submitting or importing form data, and resets form fields. This option retains form objects to which actions are linked. Flatten Form Fields.
This is useful for large documents, which can take a long time to draw page thumbnails after you click the Page Thumbnails button. Discard Document Tags. Removes tags from the document, which also removes the accessibility and reflow capabilities for the text. Convert Smooth Lines To Curves. Reduces the number of control points used to build curves in CAD drawings, which result in smaller PDF files and faster on-screen rendering.
Detect And Merge Image Fragments. Looks for images or masks that are fragmented into thin slices and tries to merge the slices into a single image or mask. Discard Embedded Print Settings. Discard Embedded Search Index. Discard Bookmarks. Discard All Comments , Forms And Multimedia. Removes information in the document information dictionary and all metadata streams.
Use the Save As command to restore metadata streams to a copy of the PDF. Removes all file attachments, including attachments added to the PDF as comments. Removes links to other documents. Links that jump to other locations within the PDF are not removed. Strips information from a PDF document that is useful only to the application that created the document. This does not affect the functionality of the PDF, but it does decrease the file size. Discard Hidden Layer Content And Flatten Visible Layers.
Decreases file size. The options in the Clean Up panel of the PDF Optimizer dialog box allow you to remove useless items from the document.
