Questions
Where can I download Cisco Packet Tracer?
Use the Direct download button in the Software for your courses section above for the Windows version. For macOS, Ubuntu or the newest release, use the Official Cisco page button. Packet Tracer is free; you sign in with a free Cisco Networking Academy account or Google the first time you open it.
Can I use these tools for university assignments?
Yes. Convert photos of handwritten work to PDF, merge chapters, add page numbers, compress files for your portal and sign forms, all for free and without uploading your work anywhere.
Are my files uploaded anywhere?
No. Files are processed inside your own browser on your phone or computer. They are never sent to a server, so they stay private.
Which formats can I convert?
PDF, JPG, PNG, WebP, GIF, BMP and SVG images, Word (.docx), Excel (.xlsx) and CSV files, and plain text. You can also merge, split, compress, sign and number PDFs, put several photos on A4 sheets, crop and resize images, combine spreadsheets, and translate between Arabic and English.
Why doesn’t PDF to Word keep my layout?
PDF to Word copies the text so you can edit it; the original layout, fonts and pictures are not carried over. Scanned PDFs are photos of pages, so they have no text to copy.
Is there a file size limit?
There’s no fixed limit. Very large jobs depend on your device’s memory. If one stops, try fewer files at a time or a lower quality setting.
