Smaller frame, same content
Cropping shrinks the page window without touching the content: text stays text, nothing is rescaled or
re-rendered. It is the fix for scanner black borders, for the enormous margins of academic papers read on tablets
and e-readers, and for trimming a slide export to its actual content.
One honest limitation, stated plainly: cropping hides, it does not delete. The content streams outside the crop
still exist inside the file — so never use cropping to remove sensitive information. For that, export the pages as
images with PDF to JPG and rebuild with Image to PDF, which
physically discards everything outside the picture.
Frequently asked questions
What is PDF cropping good for?
Cutting the black scanner edges off scanned documents, trimming huge margins so a paper reads better on a tablet or e-reader, and tightening slides for printing. The content is not scaled — the visible window just shrinks.
Is the cropped area really gone?
This tool sets both the crop box and the media box, so viewers and printers treat the page as its new size. The underlying content streams still exist inside the file (that is how PDF works); for redaction of sensitive content, cropping is not the right tool.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
