What is it? PDF Crop, N-up & Repair crops margins per side in points, imposes pages in an N-up grid (2/4/6/9 per sheet; row, column or serpentine order; paper = source pages, A4 or Letter) and can repair structurally damaged PDFs — with a local first-page preview (crop box / N-up grid overlay) and an in-page preview of the result before you download, in the browser.
TL;DR: Crop margins, impose N-up pages or repair a broken PDF — preview the result before you download. Free, local, nothing uploaded.
How to use
- Drop in a PDF — a first-page preview renders locally (nothing is processed until you click).
- Choose crop (each side in pt), N-up (per sheet + order + paper size) or repair; the preview overlays the crop box or imposition grid.
- Click "Apply" — the result's first page previews in the page; click "Download result" to save it.
FAQ
What does the serpentine order do?
It fills the grid like falling dominoes: even rows run left→right, odd rows run right→left (1,2 / 4,3 on a 2×2 sheet). Row-major and column-major are also available.
What does the paper size option do?
"Same as source pages" keeps the original page size as the sheet (default); A4 or Letter replaces it. The sheet orientation follows the first page — a landscape source gets a landscape sheet.
What does repair do?
It re-parses the document leniently and rewrites the object streams — this recovers mildly damaged files (broken xref/object streams); content that is missing from the file cannot be restored.
Does N-up keep text quality?
Yes — pages are embedded as vector content and scaled into the grid (no rasterization); the output is a rebuilt document, so bookmarks and form fields are not kept, while title/author/subject/keywords metadata carries over.
Is it local?
Yes.
Is it free? Do I need an account?
Crop, N-up and repair are free with no sign-in — just drop the file. A daily free allowance applies, and higher quotas are the paid Pro tier.
Does cropping delete the content?
No — cropping only sets the CropBox, the visible frame: everything you crop out is hidden, still in the file, and takes effect when printing or exporting. Each side is set in points separately, and you can check the dashed frame on the preview before applying.
Can I use it instead of Acrobat or Bluebeam to crop a PDF?
Yes — it runs in your browser with no install and no upload, so private files never leave your device. Set margins per side in points, preview the kept area, then apply; Acrobat-style redaction or content editing is a different job.
Does it do booklet imposition?
No — this is grid N-up (2/4/6/9 pages per sheet in row, column or serpentine order). It is built for handouts, labels and saving paper, not saddle-stitch booklet binding; use dedicated prepress software for booklets.
Can it repair a PDF that won't open at all?
Only mild structural damage — broken xref or object streams — is recovered by lenient re-parsing and rewriting. A file the parser cannot read, or content missing from the file, cannot be restored; for severe damage, desktop repair tools have a better chance.
Examples
- Drop in a PDF → pick crop/N-up/repair → apply → preview the result → download

Limitations
- Crop only sets the CropBox (content is kept, not deleted); each side is settable in points.
- N-up embeds pages as vector content (no rasterization); the output is a rebuilt document — bookmarks and form fields are not kept, Info metadata (title/author/subject/keywords) is carried over. Paper defaults to the source page size; A4/Letter sheets follow the first page's orientation.
- Repair re-parses and rewrites the structure: mildly damaged files recover, missing content cannot be restored.
- The input preview overlays the crop box or imposition grid; after applying, the output's first page is previewed the same way (a local pdf.js render — if it fails on an encrypted/damaged file, downloading still works). With A4/Letter paper the grid overlay is drawn for the chosen sheet size.
- Processed locally in your browser; nothing is uploaded.
