Working with files

File size limits, large documents, password-protected PDFs, and how BoringPDF treats your original file.

File size limits

Each file can be up to 100 MB, and the files you add to a tool at once can total up to 200 MB.

Because processing happens on your device, how quickly a job finishes depends on your computer's memory and on how complex the document is. Image-heavy PDFs need the most memory.

Large documents

  • Close other memory-heavy tabs before processing a large file.
  • Use Split PDF to break a very large document into parts, process each part, then Merge PDF the results.
  • Use Compress PDF first if a scanned document is mostly images.

Password-protected PDFs

If a PDF is password protected, enter its password when the tool asks for it. To remove a password permanently, use Unlock PDF. To add one, use Protect PDF.

BoringPDF can't recover or bypass a password you don't know.

Your original file

BoringPDF never changes the file you add. Every result is a new file that you download. Files stay in the tool only while it's open: leaving or reloading the page clears them.
