Using the Tools

What file formats are supported?
We primarily work with PDF files. For conversion tools, we support formats like JPG, PNG, WebP, Word (DOCX), Excel (XLSX), and PowerPoint (PPTX).
Why is my PDF not processing?
This can happen if the PDF is corrupted, password-protected (use our Unlock PDF tool first), or if there are network issues. Try refreshing the page and uploading again.

Our Compress PDF tool offers different compression levels. Choose "Low" compression to maintain maximum quality while still reducing file size.
