Why pdfdots?
Private by design
All processing happens locally in your browser. Your documents are never uploaded to a server, so nobody else can see them.
No limits
No daily task caps, no file-count limits and no premium tier. Process as many PDFs as your device can handle.
Fast
There's no upload or download queue. Work starts the moment you drop a file and finishes at the speed of your own computer.
Works everywhere
Windows, Mac, Linux, iPhone, Android or Chromebook — if it has a modern browser, pdfdots runs on it. Nothing to install.
Remove wide margins and focus on the content
Scans and exports often come with far more border than content: a book scanned on a flatbed with dark edges, a presentation saved with a wide frame, or an A4 page where the text only fills the middle. Crop PDF lets you trim those margins by percentage on each side, top, right, bottom and left, and shows the result on a live preview before you commit. The same crop is applied to every page, which is what you want for a consistently laid out document.
The tool runs entirely in your browser and your file is never uploaded. Technically, we set the crop box of each page. That changes the visible area in viewers and when printing, and it is fast and lossless, because nothing is re-rendered and text stays sharp and selectable.
It is worth understanding what that means. Content outside the new box is hidden, not deleted. It remains in the file, and some editors can reveal it again by resetting the crop box. That is fine for margins, but not for removing a name, an account number or a stamp. If something has to be gone for good, use Redact PDF, which truly removes the content under the boxes you draw. And if only a few pages need a different crop, extract them first and crop them separately.
Our take
We crop PDFs when the useful part of each page is surrounded by waste: wide white margins on a scanned book, a slide exported with a huge frame, or a document we want to read comfortably on a phone or e-reader.
We usually start with small values, around 5 to 10 percent per side, and watch the live preview. Remember that one setting applies to every page, so we check a few pages with different layouts before saving, because a page number near the edge is easy to lose.
The pitfall: cropping only hides what lies outside the new box. The content is still inside the file and can come back in another program. When something must be removed for real, we use Redact PDF instead.
