Tutorials on Merge PDF Online Free
Short, practical guides that go with this tool.
🔒 Your privacy with Merge PDF Online Free
Merge PDF runs as client-side JavaScript inside your own browser tab. Your file or text is read, processed, and turned into a result on your device — it is never sent to, stored on, or seen by Toolkitties' servers. Closing or refreshing the page clears everything.
Frequently asked questions
Does merging reduce the quality of my PDF pages?
No. Pages are copied into the new file rather than turned into pictures, so text stays sharp and selectable.
Can I merge only some pages of a PDF?
Yes. After adding a file you can choose the pages to include, so you can leave out cover pages or blank pages.
How do I merge PDFs on my phone?
Open Merge PDF in your phone browser, tap to add your PDFs, arrange them and tap merge. It works the same way as on a computer.
Why is my merged PDF large?
The merged file is roughly the sum of the files you added. If it is too big for email, run it through Compress PDF afterwards.
Will bookmarks and form fields from the original files be kept?
The tool is built to combine page content. Extras such as bookmarks or fillable fields may not carry over, so check the result if you need them.
Is there a limit on file size or number of files?
Toolkitties sets no account limit. The practical limit is your device memory, because everything is processed in your browser.
Is Merge PDF free to use?
Yes. Merge PDF is 100% free, with no signup, no daily limit and no paid plans.
Do I need to create an account to use Merge PDF?
No signup or login is required. Open the page and start using Merge PDF immediately.
Is it safe to use Merge PDF with private or sensitive files?
Yes. Merge PDF processes your file locally in your browser using client-side code. The file itself is never uploaded to Toolkitties' servers.
Will Merge PDF work on a large PDF?
Most PDFs process in a few seconds. Very large files (100+ MB) depend on your device's memory, since everything happens in your browser rather than on a remote server.
