What is it?

PDF (Taşınabilir Belge Formatı), 1993 yılında Adobe tarafından oluşturulmuş ve 2008 yılında açık bir standart haline gelmiştir. Metin, yazı tipleri, vektör grafikleri ve resimler dahil olmak üzere belgeleri, herhangi bir cihaz veya işletim sisteminde aynı görünen sabit bir düzen içinde yakalar.

PDF'ler, formlar, köprüler ve dijital imzalar gibi etkileşimli öğeler içerebilir. Şifreleme ve parola korumasını destekler, bu da onları dünya genelinde yasal, finansal ve resmi belgeler için standart hale getirir.

Frequently Asked Questions

Can I edit a PDF file?

Yes, but you need PDF editing software. Adobe Acrobat is the most capable option. Free alternatives include LibreOffice Draw and various online PDF editors for simple changes.

Why is my PDF so large?

Large PDFs usually contain high-resolution images or embedded fonts. Use a PDF compressor to reduce the size - our tool can often reduce PDFs by 50-80% without visible quality loss.

How do I password protect a PDF?

Use a PDF editor or our online PDF protection tool to add password encryption. You can set separate passwords for opening and for editing/printing the document.

Is PDF the same as a scanned document?

Not always. A PDF can contain real text (searchable and copyable) or just an image of text (a scan). Scanned PDFs need OCR processing to make the text searchable.

What is PDF/A?

PDF/A is an ISO-standardized version of PDF designed for long-term archiving. It embeds all fonts and color profiles and prohibits features like encryption that could affect future readability.
