Start by accessing our online PDF Filler for free, to get started.

Add Images and Shapes


The PDF filler can also add images into your PDF forms. While you have the document opened, click 'Add Image' to browse and insert an image straight from your computer, into the fillable pdf.

When it comes to shapes, we can fill PDF with arrows, squares, and circles. You can also adjust the color and thickness of the body and border of these shapes, in any way that you like.

Freehand Drawing


Lastly, click 'Draw' to do just this - fill your PDF file with freehand drawings. This function is particularly useful if you are using a stylus on your mobile or tablet.

Similarly, you can adjust the thickness and color of each stroke of your drawings. Remember to click 'Apply' and download your file.

eSign PDF forms


Although we have the 'Draw' function, if you wish to sign the form electronically, we'd suggest switching to our eSign PDF feature instead. Yes, it's also free to use online.

  1. Access the eSign tool, or click 'to eSign' on the result page of the PDF filler.

  2. Click 'Place Signature' to create a brand new e-signature, or apply an existing signature into your form.

  3. 'Apply' and download your file.
