لماذا تحتاج هذه الأدوات
PDF editing is one of the most common digital tasks, yet traditionally requires expensive software like Adobe Acrobat Pro ($240/year). For most users, the editing needs are straightforward: add a note to a document, highlight a key section, fill in a form, or fix a corrupted file. PDFBasic provides these capabilities for free, directly in your browser, with no installation or subscription. Our OCR tool is particularly valuable — millions of documents exist only as scanned images, making them impossible to search or copy text from. OCR adds an invisible text layer that makes these documents fully functional. The Flatten and Repair tools address critical document management needs that many users don't know solutions exist for until they encounter the problem.
