Which tool do you use to check pdf/A-3 validity ?
Is your PDF generated by sannypdf (I don't know this lib) valid before adding factur-x ?
Can you share a pdf example before and after ?

i dont have before because I just get content from a html
but this is the result:
20240417-facture-Danny_Trejonm_&_Danny_Trejonm.pdf

1 - $binaryContent = $this->snappyPdf->getOutputFromHtml($htmls, [ 'margin-left' => '0', 'margin-right' => '0', 'margin-top' => '10', 'margin-bottom' => '12', 'footer-line' => false, 'page-size' => 'A4', 'dpi' => 150, 'footer-html' => $footer, 'footer-spacing' => '0', ]);

2 - $factureXxml = $this->generateInvoiceAdfXml($dataFacturX, $project); $writer = new Writer(); $facturxPdf = $writer->generate($binaryContent, $factureXxml, null, true, [], true); file_put_contents($filePath, $facturxPdf);

Does the PDF beforehand need to already be a PDF/A-3 ?

Yes exactly, the initial pdf must be valid PDF/A for the Fx result to be valid.
The error "Glyph widths in font dictionary are not consistent with embedded font program widths." is already on your pdf.

Thank you very much
