Does it squish or shrink my pages?

No. The page box expands outward — your content keeps its exact size and position. The margin is new space added beside it, never space taken from it.

Can I write on the margins in Goodnotes or Notability?

Yes. The output is a standard PDF with wider pages and vector line art, so any annotation app treats it like a normal document — pen, highlighter, and eraser all work.

What is the Cornell template?

A study layout with a narrow cue column beside the content edge for keywords and questions, ruled lines in the main area for notes, and a summary band along the bottom for review.

How wide can the margin be?

Between 100 and 350 pt — roughly 1.4 to 4.9 inches. 220 pt (about 3 inches) is a comfortable default for handwritten notes.

Does it work on password-protected PDFs?

Yes — enter the password once when the file loads. The output is a normal unprotected PDF with the expanded pages.

Is my document uploaded anywhere?

No. The expansion and line drawing run entirely in your browser. The file never leaves your device.

1. Upload a PDF

Slides, textbook pages, or exam questions that need working space.

2. Pick side and template

Left, right, both, or bottom — blank, ruled, grid, dots, or Cornell.

3. Expand and download

Pages grow outward; the original content is never touched.

Give every PDF page room to write

Margin space is a feature

Lecture slides and textbook PDFs are designed to be read, not worked in. The moment you want to derive a formula beside the question, annotate a blueprint, or translate a paragraph in a language class, the page has no room. This tool grows each page's canvas outward — the original content stays exactly where it was, untouched — and draws a study template into the new space.

The expansion is a real page-box change, not an overlay or a screenshot. The output is a normal PDF with wider pages, so it opens in Goodnotes, Notability, Xodo, Acrobat, or any reader, and a stylus writes on it like any other page.

Templates for different kinds of thinking

Four line styles plus a blank margin, in four quiet colors.

Ruled lines

College-ruled spacing for prose notes, translations, and summaries.

Grid

5 mm squares for math derivations, diagrams, and engineering sketches.

Dot grid

Bullet-journal dots — structure without lines, for freeform sketching.

Cornell notes

Cue column plus summary band, the classic study-review layout.

Left, right, both, or bottom

Right-side margins suit right-handed annotators and most slide decks. Left margins work for right-to-left languages and left-handed writers. Both sides doubles the working space for dense problem sets. A bottom margin adds a working strip under each page — good for worksheet-style documents where answers go below the question.

Margin width is adjustable from 100 to 350 pt (about 1.4 to 4.9 inches). A faint dashed line marks the original page edge so the boundary between source content and scratch space stays visible.

Lossless by design

Nothing is rasterized, scaled, or re-compressed. The page's media box simply grows and vector lines are drawn in the new area — text stays selectable, images keep their resolution, and the file works everywhere a normal PDF does. Line colors are deliberately quiet — blue-gray, warm brown, green, or light gray — so the template guides your pen without competing with the page.
