To keep resized images clear in a Pages PDF, check their size and crop, export using the highest available Image Quality option, and compare the PDF before compressing it. Apple documents a quality menu, but no numeric PDF DPI control.

This workflow is for a Mac user whose image looks acceptable in a Pages document but becomes soft after resizing or exporting. The aim is to identify the first stage where detail deteriorates, then change the setting or image responsible. Apple’s Pages PDF export instructions provide the supported export path and explain the tradeoff between image quality and file size.

First, locate where the blur appears

Before changing your layout, compare three versions: the original image, the image as placed in Pages, and a fresh PDF exported directly from Pages. If you also made a smaller PDF afterward, keep that as a fourth version. Use the same small detail for each comparison—for example, a letter in a synthetic diagram or the edge of a geometric shape.

Compare the detail at a similar visible size. A page fitted to a large window and an image displayed much smaller are poor comparison partners. For a document intended for printing, include a sample print at the intended output size in your assessment.

The following is a diagnostic sequence, rather than an Apple guarantee about the cause of any particular export problem:

What you observe What to test next
The original already lacks the detail you need Try a more detailed original or a smaller placement.
The original looks clear, but the Pages placement looks soft Check enlargement, proportions, and the crop.
Pages looks clear, but the direct PDF looks softer Repeat PDF export with the highest available Image Quality setting.
The direct PDF looks clear, but a compressed copy looks softer Return to the direct export and reconsider compression.
Results seem inconsistent Repeat the comparison with one image and one change at a time.

Keep the direct export as your reference while testing. Otherwise, you may spend time adjusting the Pages document when the visible change happened during a later compression step.

Resize the image deliberately in Pages

Select the image, open the Format sidebar, and click Arrange. Under Size, select Constrain proportions to preserve its shape. You can drag a corner handle or enter a specific Width or Height. Apple also notes that a locked object must be unlocked before you can resize it. These are the documented object resizing controls in Pages for Mac.

Preserving proportions prevents stretching; it does not establish whether an image contains enough detail for its intended placement. Treat the placement size as a separate test. In a working copy, make the image smaller and export again. If the smaller version meets your needs, you have a practical layout option. If the larger placement is essential, compare it with a more detailed source image before changing the rest of the document.

Check the crop as well as the outer dimensions

A modest frame can still contain a tightly enlarged portion of an image. Double-click the image to reveal its mask controls, inspect the framing, and click Done after making adjustments. Apple describes masking as hiding unwanted portions without modifying the image file. See its Pages image editing guide.

For a useful comparison, make one version with the full graphic visible and another with your intended crop, keeping their outer widths equal. Export both together. If only the tight crop looks inadequate, reconsider how much of the original you are asking that frame to show. This test helps separate a framing problem from a document-wide export problem.

Export a fresh PDF with the documented quality control

Once the placement is settled, create a PDF directly from Pages:

  1. Open the document and choose File > Export To > PDF.
  2. Open the Image Quality pop-up menu and choose the highest-quality option available in your version.
  3. Include comments or smart annotations only if the document needs them.
  4. Click Save, enter a distinctive filename, choose a destination, and complete the export.

Apple states that higher image quality produces a larger file. Its current guide does not enumerate the quality labels or document a numeric PDF resolution field, compression percentage, or per-image export setting. Use the controls actually shown in your version rather than looking for an assumed “300 DPI” option. The steps above follow Apple’s Pages export documentation.

Open the new PDF and inspect the detail you selected earlier. For this first comparison, use the untouched export. If it is satisfactory, keep it as the reference copy before trying any size reduction.

Keep file-size reduction separate from image resizing

Pages has a separate File > Reduce File Size command. In Apple’s current documentation, Scale down and convert images scales images to the resolution used in the document and may convert some formats. The dialog offers Reduce This File, which changes the original document, and Reduce a Copy, which preserves it. Apple explains these options in Reduce a document’s file size in Pages on Mac.

When diagnosing blur, start from the unreduced document if you still have it. Establish the final image dimensions, export a reference PDF, and only then test reduction on a copy. This order makes your comparisons easier to interpret: you can assess placement, export quality, and file-size reduction independently.

Apple also notes that, within the reduction workflow, images in formats that cannot be viewed on iPhone or iPad are converted even if the image-scaling checkbox is unselected. Leaving that checkbox off is therefore not a documented promise that every embedded image remains untouched. The same file-size reduction guide describes this limitation.

Check whether Preview compression introduced the change

If you exported the PDF again from Preview, compare that copy with the direct Pages export. Apple explicitly warns that compressing a PDF may lower its quality. Its documented options include the Reduce File Size Quartz filter, Optimize images for screen, and Save images as JPEG. These belong to a later processing stage, described in Reduce the size of a PDF in Preview on Mac.

If the direct export is clear and the smaller copy is not, use the direct export as your starting point. If a smaller file is necessary, save each compression experiment under a separate name and compare the same detail again. Choose a result that remains useful at the document’s intended viewing or print size.

Does Keynote provide a sharper PDF workaround?

Apple documents the same type of PDF control in Keynote: File > Export To > PDF, followed by an Image Quality selection. Higher quality increases file size, and each slide appears on its own PDF page. Its guide does not document a numeric PDF DPI setting. See Export to PowerPoint or another file format in Keynote on Mac.

That documentation provides no basis for promising that moving a Pages layout into Keynote will fix blurry images. Keynote can be appropriate when the deliverable is already a slide presentation, but rebuilding a document there adds layout work without a documented sharpness advantage.

Be careful when following advice about Keynote resolution controls: Apple’s custom Resolution setting appears under movie export. Exporting slides as images is another separate output. Neither establishes a PDF resolution control. Keep the task focused on producing a clear Pages PDF unless you actually need a different deliverable.

What if the source image still needs more detail?

For photos, current Pages documentation includes an optional Super Resolution feature. Apple says it increases photo resolution and requires an Apple Creator Studio subscription, an Apple Intelligence-capable device, and availability in your country or region. Select the photo and click Super Resolution in the toolbar, as described in Edit an image in Pages on Mac.

This is an image editing operation, separate from the PDF export settings. Evaluate its result in a working copy and inspect the exported PDF afterward. Apple’s documentation does not promise an exact reconstruction of missing original detail or a guaranteed result for every resized graphic.

Finish with the version that passes your actual use case: the required layout, readable image details, and acceptable output size. Preserve the source document and the clear direct PDF so that any later resizing or compression can be compared against a known reference.
