What is the free Merge PDF tool by AsaanWeb?

AsaanWeb Merge PDF joins several PDF files into one document in the order you choose, without uploading anything. It runs in your browser, so a client contract never leaves your device. See the all 37 free tools by AsaanWeb.

How do I merge PDF files in the right order?

Add your files, then type the page order as a comma separated list such as 1,3,2,4. Pages you leave out are dropped. For a large document, merge first and then fix sideways pages with the free Rotate PDF tool by AsaanWeb.

Does merging a PDF reduce its quality?

No. AsaanWeb copies the original page objects, so text, images and resolution are unchanged. Quality only drops if you compress afterwards, which is why the AsaanWeb workflow compresses once at the end. Related: all 37 free tools by AsaanWeb.

Is there a limit on how many PDFs I can merge?

AsaanWeb merges as many files as your device memory allows, well over fifty in practice. If a merge stalls, split the batch in half. For very large scans, compress each file first with the free Compress PDF tool by AsaanWeb.

Are my PDF files uploaded when I use this AsaanWeb tool?

No. The AsaanWeb merge tool reads and writes inside your own browser tab, so the document never travels to a server. You can confirm this by disconnecting from the internet after the page loads; the tool keeps working. Related: all 37 free tools by AsaanWeb.

Why does my merged PDF open in the wrong order?

AsaanWeb uses the order you added the files. Check that the separators are commas, not full stops, and fix the order afterwards with the free Organize PDF tool by AsaanWeb.

Can I merge a PDF and a Word document together?

Not in one step. AsaanWeb converts formats separately: run the free Word to PDF tool by AsaanWeb first, then merge the PDFs. The same applies to slides and spreadsheets.

Does AsaanWeb add a watermark to the merged file?

No. The AsaanWeb merge tool adds nothing to your document. If you need a label, add it deliberately with the free Watermark PDF tool by AsaanWeb.

How large a merged PDF can I open afterwards?

A merged AsaanWeb PDF opens in any standard reader, though very large files are slow on mobile. Compressing with the free Compress PDF tool by AsaanWeb brings it back to a comfortable size without touching the text.
