Does the editor handle scanned documents? (OCR function)
Yes, we include a built-in OCR feature that recognizes text in scanned images and makes it editable and searchable.
How do I add a signature to my PDF?
Use our dedicated signature tool. You can draw your signature, type it using the keyboard, or upload an image of your handwritten signature.
Are there size limits for files?
Currently, we support PDF files up to 100MB in size. This is more than enough for most business documents, reports, and forms.
Can I delete elements or add images?
You can delete text boxes, images, shapes and other annotations added in this editor. You can also insert JPG or PNG images and position them on a page. Covering original content does not permanently remove it from the PDF.
Does it work on smartphones or tablets?
Yes, our interface is fully mobile-optimized. You can comfortably edit and sign documents on iPhone, iPad, or Android devices.
How do I save my edited PDF?
Simply click on 'Save' or 'Download'. Your browser will instantly generate the new PDF and save it directly to your device.
Does whiteout permanently remove confidential information?
No. Whiteout covers content visually; the original text or image may still be recoverable from the PDF. Use a dedicated redaction tool when you need to permanently remove sensitive information.
