Scans. Slides. A phone screen.
The moments when the white border has to go.
"The scan has two inches of white."
A law student in Bologna scans a textbook chapter on an A3 flatbed — half the page is margin. Crops to the text box, prints two-up, saves a ream of paper.
crop Crop to content"Slides won't fit the projector."
A consultant in Chicago has a deck exported with thick letterbox bars. Crops every page to 16:9 in one pass, so it fills the screen at the 9 AM board meeting.
aspect_ratio Crop all pages"Reading a PDF on the phone is painful."
A commuter in Seoul keeps pinch-zooming a journal article. Crops the wide margins once, and the text fills the screen big enough to read on the train.
smartphone Crop for mobile"The signature block runs off the edge."
An admin in Lagos has a form from a lopsided scan. Drags the crop box to straighten the frame, exports a clean, centred page before the courier arrives.
content_cut Crop + centerReviews from people who finally trimmed the margins.
"Cut the white border in seconds."
Our scanner adds a huge margin to every page. I cropped 60 pages to the content box in one click — the PDF looks like it was made digitally.
"Slides finally fill the screen."
A client sent a deck with black bars top and bottom. Cropped every page to 16:9 in one pass and it looked right on the projector.
"Readable on my phone at last."
I read research papers on the train. Cropping the margins once makes the text big enough that I stopped pinch-zooming. Lossless too.
