Merge PDFs into a single file

Updated 28 September 2026

To merge PDFs, drop them in, drag them into place and press Merge, and you get one new PDF with every page in sequence. Whenever your browser supports it, the merge runs on your device and the documents are never uploaded.

Typical jobs look like this: a job application built from a cover letter, a CV and two references, a year of bank statements for a mortgage broker, or a stack of scanned receipts for an expense claim.

How to combine several PDFs into one

1. Add the PDFs by dragging them in, or click the drop zone to browse to a folder.
2. Move the file cards around until they sit in the order the pages should follow.
3. Press Merge.
4. Save the combined PDF.

What the merged file keeps

Pages are copied, not redrawn and not compressed again. Selectable text, fonts, vector graphics, embedded images and web links come across unchanged, so quality does not drop. The flip side is size: the result weighs roughly as much as the originals put together.

Three things may not make it through. Bookmarks, the clickable contents list a reader shows in its side panel, can go missing. Fillable form fields may not survive either. A digitally signed PDF stays readable after merging, but its signature will not validate anymore. When the signature matters, send the signed original as a separate file.

Where the merge runs

Merging runs in your browser whenever the browser supports it. The PDFs are read from your disk, joined in memory and written to your downloads. Nothing is sent to our servers, and no account is needed. That makes the tool a sound choice for payslips, contracts, medical letters and anything else that should stay private.

If a job has to run on our servers instead, the files travel over an encrypted connection, are processed in Germany and are deleted automatically within two hours.

How many PDFs you can merge

In the browser there is no cap on the number of PDFs, no limit on pages and no daily cap. Your device sets the pace: speed and memory depend on it, so a phone will struggle with a very big merge sooner than a laptop.

Only if a job has to run on our servers do the plan limits apply: 5 files without an account, 10 with a free account and 500 with Pro. On those server jobs, files can be up to 50 MB each on the free plans and up to 500 MB on Pro, which costs EUR 7.99 a month or EUR 59 a year. For a large server job without a subscription, credits cover it: packs start at 20 credits for EUR 4.99, and credits never expire.

For a bundle you rebuild every week, set it up once in the pipeline builder and save it as a preset. A free account holds one preset, and Pro has no limit on them.
