CodeASystem PDF tools
Trim the edges of every PDF page.
Choose the margins to remove, then download a new PDF with a smaller visible page area.
Crop PDF pages
Trim the same margins from every page, then download the updated PDF.
Your file stays in this browser tab. It is not uploaded to CodeASystem.
How it works
Set the margins once for every page.
Enter the space to trim from each edge in points. The tool updates each page’s crop box, which changes the visible area without uploading your file. It is intended for ordinary, unlocked PDFs, so check the download before sharing or relying on it.
