If Your PDF File Is Not Compatible
Some uploaded PDFs can’t be processed correctly because they were created with unsupported features, CMYK color spaces, or a newer PDF version (1.5 or higher). These files often come from advanced design tools like Adobe Illustrator, CorelDRAW, or InDesign.
To make sure your document displays correctly, can be signed, encrypted, or previewed safely, it needs to be converted to PDF version 1.4 with RGB colors.
Why Version 1.4 and RGB?
🧩 Compatibility: PDF 1.4 (from Acrobat 5) is the most widely supported version. All modern PDF libraries—including those used by browsers, printers, and Laravel Cloud tools—can open it without issues.
🎨 Color safety: RGB colors are standard for screen viewing. CMYK is meant for print and can cause blank or distorted previews when displayed online.
🔒 Security and processing: Many sanitizing, encryption, and signing tools only support RGB and older PDF features. Normalizing to 1.4 ensures every page, font, and image can be safely processed.
