Selected input page
Trim edges (%). PDF crop hides content; it does not redact it.
Click for text/date/signature; drag for other marks. Marks are a visual overlay. Existing selectable text is retained. Use Redact area for permanent pixel masking in a newly rendered image-only PDF. Ordinary rectangles, highlights and cropping only hide content. Inspect the exported copy before sharing. Editing existing paragraph text is not supported.

Eligible PDF copies include the original colorful logo with Made, Scanned or Printed with FileFatafat branding in a verified clear area or added footer space. Protected originals, strict formats and size limits take priority. Standalone image exports have no visible watermark. Generated download names include _FileFatafat once. Originals are unchanged.
Add a note without pretending to rewrite the original
Add text, a date, a signature image, highlights, rectangles or handwriting over a page. For example, place a reference number in a blank margin without obscuring the original certificate text. Text and ordinary marks are exported as PDF objects; this is not a word processor for changing existing paragraphs.
Choose the relevant page, select a marking tool and inspect the output at a readable zoom. If you need redaction, use the explicit redaction mode and accept image-only output. A visual rectangle or crop alone is not a secure way to remove underlying information.
How to use add text and annotations to PDF
Choose the PDF, preview the page to annotate and select the mark type. Add the note or signature, prepare the copy and review every affected page before downloading or sharing.
Check the requirements on your form
Editing can invalidate digital signatures and affect interactive fields. Use only documents you are entitled to edit. Do not alter credentials, certificates or identity details to mislead someone.
Will my file be uploaded?
No. Processing happens in your browser, including PDF rendering, scanning and ZIP creation. Tool code is downloaded from this website; the documents you select are not sent back.
Can every file reach the requested size?
No. A size limit is a maximum, not an exact guarantee. Detailed or multi-page documents may need a larger limit to remain readable. One KB here is 1,000 bytes. Check clarity and any minimum file size before submission.
Can I change the original text?
This tool adds annotations and overlays; it does not replace existing paragraphs like a word processor.
Is a black rectangle the same as redaction?
No. Use the dedicated redaction option and its image-only export, then verify that the sensitive material is absent from the output.
