Frequently asked questions
Can I edit the existing text?
You can cover existing text with White-out and type new text on top, which works well for small corrections.
How do I add text to a PDF?
Open the PDF, choose the Text tool, click where the text should go and type. You can set the font, size and color, and drag the text to move it.
Can I add an image or logo?
Yes. Choose the Image tool, pick a picture and place it on the page. It can be moved and resized until you save.
How do I cover up a mistake?
Use White-out to place a white box over it, then add new text on top if you need to. The original text is still in the file underneath, so use Redact PDF for anything sensitive.
Can I change or remove something I added?
Yes. Every item you add can be moved, resized or deleted until you save, and “Remove all” clears the page in one click.
Is it really free?
Yes. There is no sign-up, no daily limit and no watermark added to your files.
Are my files uploaded to a server?
No. ModifyPDF processes files with JavaScript inside your browser. Your documents never leave your device, and nothing is stored after you close the page.
What you can add
Add text in your choice of font, size and color, place images such as logos or photos, highlight passages, draw boxes, or white-out areas. Every item can be moved, resized and deleted until you save, and “Remove all” clears the page in one click.
Good to know
Additions are placed on top of the existing page, so the original content stays intact underneath. To hide existing text permanently, use Redact PDF instead of covering it with a shape.
What “editing a PDF” usually means
PDFs are designed as final, print-like documents, so most editing is adding to a page: filling in a field that isn’t fillable, adding a note, correcting a date, or placing a logo. For heavy rewrites of the original text, it’s usually better to edit the source document and export a new PDF, or convert it with PDF to Word.
Covering vs. removing
A white box over text hides it on screen and in print, but the original text is still in the file and can be copied out. For anything sensitive, use Redact PDF, which removes it.
