Frequently Asked Questions
Is this PDF merger free?
Yes, merging PDFs is completely free with no daily limits and no signup required. Just upload your files and merge as many times as you need.
Is it safe to merge PDFs online?
Yes, your files are processed locally in your browser and never uploaded to our servers. This makes our tool more private than competitors that require file uploads.
How many PDFs can I merge at once?
There is no limit on the number of files per merge, and no daily limit on how many merges you can perform. Combine as many PDFs as you need into a single document.
Will merging affect the quality of my PDFs?
No. Merging is lossless — your pages, text, images, and formatting remain exactly as they were in the original files. Nothing is compressed or altered.
What is the maximum file size for merging?
Free users can merge PDFs up to 50 MB each. Pro users can merge files up to 2 GB each. Processing happens in your browser, so performance depends on your device.
Can I choose the page order when merging?
Yes. Simply drag and drop files to rearrange them in your preferred order before merging. You'll see a thumbnail preview of each file so you can verify the sequence at a glance.
Does the merger work on my phone?
Yes, our PDF merger works on any modern browser — desktop, tablet, or phone. No app installation required. Just open the page, upload your PDFs, and download the merged file.
Can I merge PDFs and then compress the result?
Yes — after merging your PDFs, you can use our free Compress PDF tool to reduce the file size. This is great when the combined document is too large to email or upload.
