Optimize images for Google Docs PDF export

Google Docs stores the original resolution of every image you add, even if you visually shrink it on the page. A 4000x3000 photo dragged into a half-page slot still exports at full size. Resize images to roughly the dimensions they will occupy in the document before inserting them, keeping width under 1500 pixels for most layouts.

PNG works best for screenshots, diagrams, and anything with text or sharp edges. JPEG is better for photos and complex gradients where exact pixel accuracy matters less. Avoid BMP and TIFF entirely, as Google Docs converts them internally but the results can be unpredictable.

Run images through a compression tool like TinyPNG or Squoosh before inserting. A well-compressed JPEG at 80% quality is virtually indistinguishable from the original but can be 60-70% smaller. This directly reduces your final PDF file size.

Use the 'In line' text wrapping option for the most predictable PDF output. 'Wrap text' and 'Break text' sometimes shift position during export, especially near page boundaries. If you need side-by-side images, use a table with invisible borders to lock their position.

Always open the exported PDF and zoom to 100% to check image quality. If anything looks soft or pixelated, the source image was too small. Replace it with a higher-resolution version and export again. Quick PDF previews save you from sending a blurry file.
