How it works
Frequently asked questions
Is this PDF tool really free?
Yes. All tools are free to use with no sign-up, no watermark on your output and no hidden fees. The site is supported by advertising.
Are my files uploaded to a server?
No. Every tool runs inside your own browser using JavaScript, so your documents never leave your device.
Is there a file size limit?
We do not set one. Because processing happens on your device, very large files depend on your browser memory, and phones may be slower than computers.
How do I merge PDF files online?
Open Merge PDF, add two or more files, arrange them with the arrow buttons and press Merge PDF. The combined file downloads automatically.
Can I convert PDF to Word or Excel?
Not at the moment. These conversions need server-side processing, and we only offer tools that run privately in your browser.
Which browsers are supported?
Any modern browser, including Chrome, Edge, Firefox and Safari, on computers, phones and tablets.
