Frequently asked questions

How large a file can I process?
Up to 250 MB, because the work happens on our server rather than in your browser’s memory.
What formats can I merge?
PDF, JPG, PNG, WebP, GIF and TIFF — up to 60 MB each — into a single PDF.
How can I split a large PDF?
Choose specific page ranges to extract, or use burst mode to divide the document into smaller PDF files.
