PDF Forms
Fill out and edit PDF forms easily with interactive drag-and-drop fields.
What is Fill PDF Forms?
Type onto a PDF, tick boxes, and add a signature by placing text and shapes over the page. Free, private, and processed entirely in your browser.
When should you use it?
This tool is useful when you need to add, change, or clean up visible content inside a PDF while staying in your browser.
How Fill PDF Forms handles your file
Your entries are drawn onto a rendered image of each page in your browser, then written into a new PDF. Nothing is uploaded.
Your device's own CPU does the work, so there is no upload wait and no server-side copy of your document to retain.
Good to know before you convert
- This does not fill native AcroForm fields. It places text, shapes, and ticks over a rendered image of the page.
- Because each page is composited to an image, the output PDF has no selectable text — including any text that was in the original.
- Form fields stay interactive only in the sense that they are visibly filled; they are no longer machine-readable fields that other systems can extract.
- Output file size grows with the number of pages, since each page becomes an image.

Frequently Asked Questions
Does this fill interactive form fields?
No, and this is a meaningful difference. PdfPix does not read a PDF's AcroForm field definitions. Instead it renders each page as an image and lets you place text, shapes, and ticks on top. The form will look filled in when printed or viewed, but downstream systems that expect machine-readable field values will not be able to read them.
Can I sign the form after filling it?
Yes. The signature tool is built into the same interface, so you can draw or type a signature and place it along with the rest of your entries.
Will the text still be selectable?
No. The completed form is composited to images, so nothing in the output PDF can be selected, searched, or copied — including text that was in the original document.
Are my form inputs saved securely?
Yes. All entry happens locally in your browser and no server captures what you type.
