Check fonts, text boxes and alignment first
Compare headings, small labels and tightly fitted text boxes. Font substitution can change line length, baseline, wrapping and connector placement around text.
If exact typography is mandatory, ensure the font is available to the rendering environment or use a documented preflight process. Tagged PDF can improve structural output when the source itself has usable semantics, but it does not repair missing fonts.
- Look for unexpected wrapping.
- Check rotated and vertical text.
- Inspect clipped labels.
- Verify symbols and non-Latin scripts.

Merged PDF
New order, same page detail
Review overlapping transparent objects against both light and dark backgrounds. Check gradient direction, clipping masks, shadows, line joins and imported image sharpness.
Use Lossless for diagnostic comparison. If that version is correct, test Balanced or Compact and decide whether any change is acceptable for the delivery.
Verify navigation and optional document data
Open bookmarks and test internal or external links in an independent PDF viewer. Bookmark export, named destinations and compatible document-link conversion must still be verified because the source relationship and viewer behavior both matter.
Export notes only when they are intentionally part of the delivered document. Do not assume hidden editorial comments should travel with a public PDF.
Use an explicit acceptance checklist
Save the accepted PDF separately from experimental outputs and retain the ODG source used to create it.
| Area | Check | If incorrect |
|---|---|---|
| Typography | Wrapping, symbols, alignment | Install or replace fonts and reconvert |
| Artwork | Gradients, transparency, line weights | Use Lossless and simplify unsupported effects |
| Images | Detail and cropping | Embed the source and raise the fidelity profile |
| Navigation | Bookmarks and links | Enable the controls and verify destinations |
| Pages | Count, order and dimensions | Correct the range or source page setup |
Put the workflow into practice
Arrange source documents, select the pages you need, and create one PDF locally in your browser. Review the result before choosing any optional next step.
Try ODG to PDFFrequently asked questions
Clear answers before you merge
Why did a font change?
The rendering service may not have the exact font, causing LibreOffice to substitute another family.
Why does a gradient look different?
Complex effects can be interpreted differently by the source editor, export filter or PDF viewer.
Should I include notes?
Only when notes are intentionally part of the delivered PDF; leave them disabled for most public drawings.
Does tagged PDF guarantee accessibility?
No. Tags help only when source structure is meaningful, and the final PDF still requires accessibility review.
How should I verify links?
Test internal and external destinations in an independent PDF viewer after conversion.
