Upload multiple PDFs, arrange them in the exact order you want, and export a single polished document without switching tools.
Step 1
Step 2
Drag cards or use the arrows to control the merge sequence.
No files added yet. Start with at least two PDFs.
Step 3
Export one merged PDF in the order shown above. The first file becomes page one of the final document.
PDF only. 10MB per file. 20 files max.
Built for tidy documents
Upload your PDFs, arrange them the way you want, and export one clean file in seconds. And if the final file ends up too large to send, you can run it through Compress PDF right after to reduce the size.
This is the simplest way to merge PDF files into one PDF document without switching between tools:
Start to finish
You can upload several files at once and combine them without any complicated steps or settings to deal with. The result is one single clean file that is ready to send or save.
Before you export, you are in full control of the order your files go in. Drag them into whatever sequence makes sense for your document and the final merge follows that exact order. Nothing gets rearranged automatically.
Once your files are in the right order, exporting takes just one click. Your merged file is ready to download almost immediately with no waiting around. It comes back completely clean and ready to send or save straight away.
The online PDF editor is completely free to use and there is nothing to set up before you get started. Every page from every file comes through exactly as it was in the original, with text, images, and layout all preserved. No sign-up form, no email address, no account to create before you can get started.
No app required
Searching for a PDF merging app is the usual reflex on a phone, and it is usually unnecessary. This page is a normal website, so it works in Safari on iPhone and iPad and in Chrome on Android with nothing to install, no account, and no per-merge charge — which is what most of the free apps in the store start asking for once you try to export.
One thing to check before you send a merged file from a phone: bookmarks and fillable form fields do not survive a merge. If one of the documents is a form someone needs to complete, send that one on its own. The FAQ below covers why.
Upload the PDFs you want to combine, put them in the order you need, and export. The download is a single PDF containing every page from every file, in the sequence you set. You can merge up to 20 files at once, each up to 10 MB, with no signup and no watermark on the result.
Yes. This runs as a normal web page, so it works in Safari on iPhone and iPad and in Chrome on Android with nothing to install and no account. Tap the upload area and your phone offers its own file picker — on iPhone that includes Files, iCloud Drive, and anything shared from another app; on Android it includes Files, Downloads, and Google Drive. One difference worth knowing on a touch screen: dragging the file cards to reorder them is a mouse interaction and will not work with a finger. Use the up and down arrow buttons on each card instead — they do exactly the same job and are easier to be precise with on a small screen.
Save each attachment to your phone first, then upload them together. On iPhone, open the attachment, tap the share icon, and choose Save to Files. On Android, tap the download icon on the attachment and it lands in Downloads. Once they are saved, tap the upload area here and select all of them in one go — you do not have to add them one at a time, and you can reorder them afterwards regardless of the order you picked them in.
Neither. There is nothing to download or set up, and no signup, email address, or credit card at any point. Open the page, add your PDFs, and merge. Your files are uploaded to our server to be combined and are removed after your session, so an internet connection is required.
It is free from start to finish. You can upload your files, combine them, and download the result without paying anything or entering any payment details, and there is no cap on how many times you use it.
You can bring together up to 20 PDF files in a single merge, with each individual file up to 10 MB in size. If you have more than that, merge in batches and then merge the results.
Yes, and nothing is reordered automatically — the merge follows exactly the sequence you set. On a computer you can drag the cards into position; on a phone or tablet, use the up and down arrows on each card. Rearrange as many times as you like before exporting.
No. Every page comes through as it was in the original file, with its text, images, fonts, and layout intact. Merging concatenates the documents rather than re-rendering them, so nothing is flattened, re-compressed, or re-flowed.
No — this is the one thing merging does not carry across, and it is worth knowing before you send the result. Bookmarks (the clickable outline panel) are dropped, so a merged file opens without them even if every source document had them. Fillable form fields stop being fillable: the boxes still appear on the page because they are drawn there, but the document-level form registration is not rebuilt during the merge, so most viewers will no longer let anyone type into them. If you need a working form, send that PDF on its own rather than merged, or fill it in first and merge the completed copy. Page content, text, images, fonts, and layout are all unaffected.
Yes. Each page keeps its own dimensions and orientation in the merged file, so an A4 report and a landscape spreadsheet export can sit in the same document without either being stretched or cropped. If you would rather they all matched, run the merged file through Change PDF Page Size afterwards.
No. The downloaded file is completely clean — no watermark, no logo, and no branding added to any page.
Run it through Compress PDF after merging. Compressing once at the end works better than compressing each file first and then merging, because you avoid stacking the quality loss from several passes.
They are used only to produce your merged document and are removed once your session ends. Nothing is kept, sold, or shared with anyone.
