Todos entendemos que existem v\u00e1rias vantagens de usar o pdf<\/a> mas voc\u00ea j\u00e1 ouviu falar da alternativa \u201cPDF\/A\u201d? Se n\u00e3o, vamos analisar isso agora!!<\/strong><\/p>\n

O que \u00e9 o PDF\/A?<\/h2>\n

O uso do PDF\/A<\/a>\u00e9 destinado especificamente ao armazenamento de longo prazo e preserva\u00e7\u00e3o de documentos eletr\u00f4nicos. \u00c9 uma vers\u00e3o do formato de documento port\u00e1til que segue as normas ISO (PDF). Diferentemente do PDF, que permite recursos como criptografia e vincula\u00e7\u00e3o de fontes, o PDF\/A restringe esses recursos, pois n\u00e3o s\u00e3o ideais para arquivamento de longo prazo<\/a>. Isso significa que um documento pode ser reproduzido da mesma forma usando o formato PDF\/A, independentemente do aplicativo utilizado. Basicamente, o arquivo cont\u00e9m todas as informa\u00e7\u00f5es necess\u00e1rias para exibir continuamente o documento e todas as suas partes, mantendo seus documentos seguros, acess\u00edveis e protegidos a longo prazo.<\/p>\n

Quais s\u00e3o os diferentes tipos de PDF\/A?<\/h2>\n

Ao combinar v\u00e1rias normas PDF\/A e n\u00edveis de conformidade, s\u00e3o poss\u00edveis diversas variantes de PDF\/A. Cada norma PDF\/A descreve a variedade de recursos e m\u00e9todos de compress\u00e3o de imagens que podem ser usados para preservar o conte\u00fado de um arquivo.<\/p>\n

PDF\/A-1<\/strong>
\nA primeira norma PDF\/A, que ainda \u00e9 usada hoje e tamb\u00e9m \u00e9 a mais restritiva, \u00e9 o PDF\/A-1. Como o PDF\/A-1 se baseia na antiga norma PDF 1.4, lan\u00e7ada pela Adobe Systems em 2001, ele n\u00e3o \u00e9 compat\u00edvel com camadas, anexos ou JPEG 2000.<\/p>\n

PDF\/A-2<\/strong>
\nTranspar\u00eancia \u00e9 uma das muitas novas caracter\u00edsticas adicionadas ao PDF\/A-2 que n\u00e3o estavam presentes no PDF 1.4. Camadas, melhor compress\u00e3o de imagens (JPEG 2000 e JBIG 2) e anexos \u2014 desde que os anexos estejam no formato PDF\/A \u2014 s\u00e3o todas novidades.<\/p>\n

PDF\/A-3<\/strong>
\nO PDF\/A-3 e o PDF\/A-2 s\u00e3o quase intercambi\u00e1veis. A \u00fanica diferen\u00e7a \u00e9 que o PDF\/A-3 permite qualquer tipo de arquivo como anexo. No entanto, al\u00e9m de garantir a extra\u00e7\u00e3o correta, n\u00e3o \u00e9 necess\u00e1rio um visualizador PDF\/A para realizar outras a\u00e7\u00f5es com os arquivos anexados.<\/p>\n

PDF\/A-4<\/strong>
\nA pr\u00f3xima norma PDF\/A, conhecida como PDF\/A-4, ser\u00e1 lan\u00e7ada como ISO 19005-4:2020 em novembro de 2020. O A-4 atualiza o PDF\/A para que esteja de acordo com o PDF 2.0, a mais recente norma ISO do PDF. Notavelmente, o PDF\/A-4 n\u00e3o utiliza os n\u00edveis distintos de conformidade a, b e u.<\/p>\n

Como transformar um PDF em PDF\/A?<\/h2>\n

Existem v\u00e1rios conversores de PDF para PDF\/A dispon\u00edveis no mercado, mas voc\u00ea deve usar apenas um \u201ctipo qualquer\u201d de conversor, pois tamb\u00e9m \u00e9 uma quest\u00e3o de seguran\u00e7a cibern\u00e9tica. Por isso, sugerimos usar o VP Online Free PDF Converter<\/a>, \u00e9 um conversor excelente que permite converter seu PDF para diversos formatos, incluindo PDF\/A, e permite convers\u00e3o r\u00e1pida.
