How is this different from Merge PDF?

Merge PDF combines whole files in upload order with no editing in between. This tool works at the page level — reorder, rotate, crop and delete individual pages across one or several files before exporting, so use Merge PDF for a quick whole-file combine and this tool when you need to actually organize the pages first.

Do I need more than one file to use this?

No — it works with a single PDF or image too, for reordering, rotating or deleting its own pages; adding a second (or third) file is only needed when you also want to combine them.

Can I mix PDFs and images in the same session?

Yes — an added image becomes a single page you can reorder, rotate or delete exactly like a PDF page, and it exports embedded into the same output.

What does "Crop margins" do?

Sets that page's CropBox (the visible region PDF viewers/printers show) inward by a uniform margin on every side — the underlying page content is untouched, only the visible crop region shrinks, same as pdf-lib's own crop convention.

How does "Remove blank pages" decide what counts as blank?

It samples each page's already-rendered thumbnail and checks whether almost every pixel matches the page's own background color — no extra re-rendering needed. It can occasionally miss a page with only very faint content; check the result before relying on it for anything important.

What are the four export options?

"As one PDF" merges the arranged pages into a single PDF, keeping vector text selectable. "As images" renders every arranged page to its own PNG image. "Compressed PDF" re-compresses every page toward a target file size you set. "Flattened PDF" rasterizes every page at full quality (optionally grayscale) with no target-size search — useful when you want a fully flattened, non-editable result rather than a smaller file.

Can I add more files after I’ve already started arranging pages?

Yes — use the same upload area again at any point; its pages are appended to the end of the current list, ready to reorder wherever you want.

Does this tool upload my files anywhere?

No — every page is read, previewed, rotated and exported entirely in your browser (pdf.js for PDF previews/rendering, pdf-lib for assembling the output); files are never sent to a server.

Organize PDF Pages

Add one or more PDFs or images, drag to reorder, rotate, crop, duplicate or delete any page, then export as one PDF, as images, or as a compressed/flattened PDF.

Add PDF or image files

Drop files, paste, or click to browse

Add one or more PDFs or images — drop them all at once, or add more later. Up to 50 MB each; an image becomes a single page.

Files never leave your device — every page stays and is edited entirely in your browser.

How it works

1
Add one or more PDFs or images

Drop, paste or browse — add more files at any point in the session; each image becomes a single page.
2
Arrange the pages

Drag to reorder, rotate, crop, duplicate or delete any page; remove blank pages or keep only odd/even pages in one click.
3
Export as PDF, images, compressed, or flattened

Choose the export format: one organized PDF, one image per page, a PDF re-compressed toward a target size, or a fully flattened (optionally grayscale) PDF.
