Frequently asked questions
Is there a limit to how many PDFs I can merge?
There is no limit on the number of files. Each file can be up to 50 MB: merging runs in your browser using your device's memory, so there is no upload to wait for and nothing to pay.
Are my files safe and private?
Yes. Unlike converters that upload your files to their servers, CraftMyDocs merges your documents locally in your browser, so the files never leave your device. That makes it a good fit for confidential documents — check your organisation's own policy for anything regulated.
Will the merged PDF lose quality or formatting?
No, there is zero quality loss. Our merging engine extracts the layout, vector graphics, fonts, and high-resolution images from each source document and binds them together natively. Your hyperlinks, text selections, and formatting remain fully intact and searchable.
