Step 1 — Stop Word from compressing images
- File → Options → Advanced.
- Scroll to Image Size and Quality.
- Tick “Do not compress images in file”.
- Or set Default resolution to High fidelity.
Step 2 — Set the target export DPI
For print, change Default Resolution to 330 ppi (the highest non-fidelity option). For Save-as-PDF jobs, ensure “ISO 19005-1 compliant (PDF/A)” is enabled if archival quality matters.
Step 3 — Tag images at 300 DPI before inserting
Word respects the embedded DPI metadata when sizing images on insert. Run every image through our DPI Converter at 300 DPI first, then insert — the image will appear at its true print size and pass through to PDF cleanly.
Common mistakes
- Changing the setting after inserting — existing images stay compressed.
- Saving as “Standard” PDF — this re-compresses to 96 DPI. Use “High Quality Print”.
- Pasting screenshots from Snipping Tool — they import as 96 DPI; convert with our DPI tool first.
