Merge & Split PDF

Combine PDFs and photos into one PDF, reorder pages, and extract or split out the pages you need. Your files are never uploaded; everything happens right here in your browser.

Drop PDFs or photos here, or click to choose Pick several at once if you like. Each JPG, PNG or WebP photo becomes one page.

Drag pages to reorder them; on a phone, press and hold a page, then drag. Click a page to select it, or Shift-click to select everything in between. Dragging a selected page moves the whole selection.

Keyboard: Alt+←→ move, R rotate, Delete remove, Ctrl+Z undo. Paste a screenshot with Ctrl+V to add it as a page.

Pages from your PDFs are copied rather than redrawn, so text stays selectable and searchable at full quality. Encrypted PDFs are added as page images.

About Merge & Split PDF

What it is

A tool that combines PDFs and photos into one PDF, reorders pages, and extracts pages or splits a document into several files. Use it to bundle application documents, turn photographed receipts into a single PDF, or send just a few pages of a long report. Your files are never uploaded. Reading and assembling all happen inside your browser, so contracts and ID copies can go in as they are.

How to use it

Drop PDFs and photos (JPG, PNG, WebP) onto the page, or click the box to choose them. Each photo becomes one page, and files chosen together go in by name. You can also paste a screenshot with Ctrl+V.

Drag pages to reorder them; on a phone, press and hold a page, then drag. Rotate a page with ↻ and remove it with ×. Undo, or Ctrl+Z, takes back the last change.

Click a page to select it, or Shift-click to select everything in between. Selected pages can be rotated, removed or dragged together, or saved on their own with Save selected as PDF.

Merge into one saves the pages in their current order as a single PDF. Split into files cuts them into one PDF per page, every N pages, or ranges such as "1-3, 4-10, 11-", delivered in one ZIP.

Photo pages can be sized to the photo, A4 or Letter. A4 and Letter turn portrait or landscape to match each photo and can keep a margin.

Sources and method

Previews are drawn with Mozilla's open-source PDF engine pdf.js (3.11.174), and the new PDF is built with pdf-lib (1.17.1). Pages from your PDFs are copied as page content rather than redrawn as pictures, so text selection, search and quality match the original. Pages from the same file are copied in one pass so shared resources such as fonts go in only once. JPG and PNG photos without rotation data are embedded byte for byte, with no recompression. JPGs shot sideways on a phone (with an EXIF orientation value) and formats such as WebP are redrawn upright by the browser and stored as quality-92 JPGs. ZIP files are packed with JSZip (3.10.1).

Limits

Encrypted PDFs cannot be copied page for page, so their pages go in as 200 dpi images. Text on those pages cannot be selected or searched, and the file grows. Such files are marked "as images" next to their name.

Bookmarks (outlines) from the originals do not carry over, and some form fields and links may be lost.

HEIC photos open only in Safari. In other browsers, convert them to JPG first.

Merging several large files of hundreds of pages can run out of memory on a phone. Use a computer or merge in smaller batches.
