Frequently asked questions
Do you upload or store my PDF files?
No. All processing happens locally in your browser. Your PDF files are never sent to any server. We use PDF-lib, a JavaScript library that runs client-side, so the data never leaves your device.
How do I merge multiple PDF files into one?
Open the PDF Merger, drag your PDF files into the drop zone, reorder them if needed, then click Download. The merged PDF is assembled in your browser and downloaded directly.
How do I split a PDF into individual pages?
Open the PDF Splitter and drop your file. You can split every page into its own file or enter a custom range like "1-3, 5, 7-9". The resulting pages are downloaded as separate PDF files.
Can I convert JPG and PNG images to PDF?
Yes. The Image to PDF tool accepts JPG, PNG, GIF, and WebP images. Drop one or more images, choose the page size, reorder if needed, and download the resulting PDF.
Do these tools work offline?
You need a connection for the first page load to download the tool. After that, the processing logic is cached in your browser and the tools can run without a network connection.
Is there a file size limit?
There is no server-side limit because files are never uploaded. However, very large PDFs (hundreds of megabytes) may be slow to process depending on your device memory and browser. For best performance, use files under 100 MB.
Can I use these tools on my phone?
Yes. All PDF tools are mobile-friendly with responsive layouts and large touch targets. Open any tool in your mobile browser — no app download required.
What is the difference between merge, combine, and join PDF?
Merge, combine, and join all mean the same thing: taking multiple PDF files and producing a single PDF document. Use the PDF Merger to do this in your browser.
