The Merge PDF tool in PDFbat with two documents loaded and ready to combine

One file instead of a folder full of attachments

Application packs, monthly reports, invoices with their receipts, a contract with its schedules: all of these are easier to send, sign and archive as one PDF. The Merge PDF tool copies every page of every file into a new document, in exactly the order you set, without re-rendering anything. Text stays selectable, links keep working and images keep their original quality.

You are not limited to PDFs. JPG, PNG and other image files, EPUB ebooks, XPS documents, CBZ comic archives and FB2 books are converted to PDF pages on the fly and merged in the same pass, so a scanned receipt photo can sit right after the invoice it belongs to.

Why merge with PDFbat

Any order you like

Drag files by their handle or use the up and down arrows to set the sequence before merging. What you see in the list is what you get.

PDFs and images together

Mix PDFs with photos, scans, EPUB, XPS, CBZ and FB2 files. Each one becomes pages in the final document.

A bookmark per file

Each source file becomes an entry in the PDF outline, named after the file, so long merged packs stay easy to navigate.

No quality loss

Pages are copied, not printed again. Text stays searchable and selectable, and images are not recompressed.

Saved to your Drive

The merged PDF lands in your private Drive automatically, ready to download, share with a link or send for signature.

How it works

  1. 1

    Add your files

    Drop two or more files onto the page, or pick them from your device or Drive. PDFs, images and ebook formats can be mixed in one merge.

  2. 2

    Put them in order

    Drag each file into place or use the arrows. Choose whether to add bookmarks and whether to insert a blank page between files.

  3. 3

    Merge and download

    Click merge. PDFbat builds one PDF in seconds and saves it to Drive. Download it or open it in another tool.

Merge options explained

Add a bookmark per file
On by default. The merged PDF gets an outline with one entry per source file, titled with the file name and pointing to its first page. Turn it off if you want a plain document without a bookmarks panel.
Insert blank page between files
Adds an empty page after every file except the last, sized to match the page before it. Useful for double sided printing, where each document should start on a fresh sheet.
Drag and drop ordering
Every file shows a thumbnail, its name and size. Drag the grip handle to move a file, or use the Move up and Move down buttons, which also work well on touch screens.
Mixed input formats
Accepts PDF, JPG, PNG and other image types, plus EPUB, XPS, CBZ and FB2. Images become a page sized exactly to the picture.
Original page sizes kept
A Letter page stays Letter and an A4 page stays A4. If you need everything the same size afterwards, run Resize Pages.
Works on encrypted output later
Merge first, then add a password to the combined file with Protect PDF.

Common ways people use Merge PDF

  • Job and visa applications: combine a cover letter, CV, certificates and ID scans into the single file most portals ask for.
  • Expense claims: put the claim form first and follow it with photos of every receipt.
  • Contracts: join the main agreement, schedules and appendices before sending the whole pack for e signature.
  • Reports: assemble chapters written by different people into one deliverable with a bookmark for each section.
  • Scanning at home: merge separate scans of the same document taken on different days.

Tips for a better merged PDF

  • Name files the way you want the bookmarks to read, for example "01 Cover letter.pdf", before you upload them.
  • If one source PDF has pages you do not need, merge first and then remove them with Delete Pages, or fine tune the order with Organize PDF.
  • Large merged scans can be heavy. Run Compress PDF on the result to make it email friendly.
  • Scanned the fronts and backs of a stack separately? Use Alternate and Mix instead, which interleaves the pages rather than appending them.
  • Add page numbers after merging so the numbering runs across the whole document.

Frequently asked questions

How many files can I merge at once?

You need at least two. You can add many more in one go; the practical limit is the upload size of your plan, 25 MB per file on Free and 100 MB on Pro.

Can I merge JPG or PNG images with PDFs?

Yes. Images, EPUB, XPS, CBZ and FB2 files are converted to PDF pages and merged in the order you set. To turn images alone into a PDF, JPG to PDF also offers page sizes and margins.

Will merging reduce the quality of my pages?

No. Pages are copied as they are, so text stays sharp and searchable and images keep their original resolution.

Can I change the order after uploading?

Yes. Drag files in the list or use the up and down arrows. To reorder individual pages after merging, use Organize PDF.

What are the bookmarks for?

They appear in the bookmarks or outline panel of PDF readers, one per original file, so a reader can jump to the start of each document. You can switch them off.

Can I merge a password protected PDF?

Remove the password first with Unlock PDF, using the password you already have, then merge.

Does it work on my phone?

Yes. Merge PDF runs in Safari and Chrome on iPhone and Android, and the arrow buttons make reordering easy on a touch screen.
