Frequently Asked Questions
Is it really free?
Yes, 100% free with no limits on the number of files or merges. There are no watermarks, no daily caps, and no premium tier hiding features. We can keep it free because everything runs in your browser — there are no server processing costs to pass on to you.
Do I need to sign up?
No. There is no account, no email signup, and no login of any kind. Just open the page, upload your PDFs, merge them, and download the result. Your work is never tied to an identity, and you can use the tool anonymously as often as you like.
Is it safe? Are my files private?
Completely safe. The merger runs 100% in your browser using JavaScript — your PDF files are never uploaded to any server. You can even disconnect from the internet after the page loads and it will still work. Nothing is stored, tracked, or shared with anyone.
Can I merge JPG images together with PDFs?
Yes. You can add JPG or PNG images alongside your PDFs, and the tool converts each image into a page of the final merged document. This is perfect for combining scanned pages, photos, receipts, and existing PDFs into a single organized file for sharing or archiving.
Can I change the page order before merging?
Yes. After uploading, each file appears as a thumbnail that you can drag into any position. The final PDF follows the exact order you arrange, so take a moment to double-check the sequence before clicking merge — rearranging takes only seconds.
Is there a file size limit?
Because merging happens locally in your browser, the only real limit is your device's available memory. Most users merge dozens of files totaling hundreds of megabytes without any issues. Extremely large files may take a few extra seconds to process, but there is no artificial cap.
