Add an image to a page
- 1Open the Edit PDF tool and drop in your PDF.
- 2Choose Images in the mode bar.
- 3Insert an image and pick the file from your device.
- 4Drag it into position and resize it to fit.
- 5Download the PDF with the image written into the page.
Replace an image that is already there
Select the existing image on the page first, then use the same Images mode to swap it for one of your own. The replacement takes the place of the original rather than sitting on top of it, which is what you want when updating a logo across a template.
Match the aspect ratio of the image you are replacing before you import it. A square logo dropped into a wide space either stretches or leaves an awkward gap, and cropping the source file is far easier than fighting it on the page.
Getting a result that looks native
- Use a transparent PNG for logos
- A logo on a white rectangle looks pasted on the moment the page background is not white.
- Match the resolution
- Import an image around twice its final size on the page. Much smaller looks soft in print; much larger just inflates the file.
- Align to the page grid
- Zoom in and line the image up with the margins and the elements around it. Being a few pixels out is visible even when nobody can say why.
- Compress afterwards if needed
- High-resolution photographs can add megabytes. Run the finished PDF through the compressor to bring it back down without rasterizing the text.
When to rebuild instead
Editing images in a PDF is the right move when the document is otherwise finished and you have a handful of changes to make.
If you still have the source file and the whole layout is changing, updating the original and re-exporting is quicker and gives a cleaner result. PDF image editing is for the very common case where the source file is gone, is owned by someone else, or would take longer to track down than the edit takes to make.
