How do I add bleed to a PDF?

Upload your PDF, specify the bleed size (typically 3 mm), choose whether trim marks should be added, click Add Bleed, and download a print-ready PDF in seconds. No signup needed.

Bleed is extra area outside the trim edge (typically 3 mm) where background colours and images continue "past the edge." When the printer cuts the sheet to its final size, bleed ensures there are no white edges even if the cut is slightly off.

How much bleed should I use?

Standard is 3 mm in Europe (and 0.125 inch ≈ 3.175 mm in the US). Some printers require 5 mm for larger products or specialty work — always check with your specific printer.

What are trim marks (crop marks)?

Trim marks are small lines at the corners of the sheet that show the printer exactly where to cut the PDF to its final size. They are required alongside bleed for correct cropping.

What is the difference between bleed and trim marks?

Bleed is the extra printable area (the colours/images themselves). Trim marks are the lines showing where to cut. Both are needed for professional printing and are typically used together.

When do I need bleed?

Whenever your design has colours, images or graphics going all the way to the edge — business cards, brochures, posters, book covers etc. If there is always a white margin around your design, you do not need bleed.

My printer requires 3 mm bleed — does my PDF already have it?

Many PDFs exported from Word, PowerPoint or directly from a design template do not include bleed. Check whether the PDF's trim box and bleed box are identical — if so, bleed is missing. This tool adds proper bleed and trim marks so the PDF becomes print-ready.
