Frequently Asked Questions

Can I edit any PDF online for free?

Most PDFs can be edited online, but some restrictions apply. Password-protected PDFs need the password, and some documents with special security settings may have limited editing capabilities. For documents that can't be edited directly, try our PDF to Word converter to edit in Word format first.

Will online editing affect PDF quality?

Quality online PDF editors like PixnPDF maintain original document quality. Changes are made to the document structure, not by converting to image format, preserving text clarity and file size.

How secure are online PDF editors?

Reputable online editors use encrypted connections and automatically delete uploaded files after processing. However, avoid uploading highly sensitive documents to any online service. For additional security, use our watermark tool to add confidentiality notices to your documents.

Can I edit scanned PDF documents?

Scanned PDFs require OCR (Optical Character Recognition) to make text editable. Advanced online editors can process scanned documents, though results depend on scan quality.

Are there file size limits for online PDF editing?

Most free online editors have file size limits, typically 10-100MB. PixnPDF supports files up to 100MB, accommodating most business and personal documents. For larger files, use our PDF compressor to reduce file size before editing, or split large documents into smaller sections.
