Frequently Asked Questions
Is my document uploaded to a server?
No. Everything happens inside your browser. Your PDF never leaves your device.
Why is the new PDF bigger sometimes?
Each page is turned into a picture so that every colour is removed reliably. A text PDF is usually very small, so the picture version can be bigger. Choose 150 DPI or a lower quality to make it smaller. The Compress PDF tool can help too.
Can I still select and copy the text?
English (Latin) text stays searchable and can be selected. Telugu, Hindi and other scripts do not. Use the OCR PDF tool if you need that.
Which mode is best for printing?
Grayscale for pages with photos. Black & white for plain text and scanned forms. Ink saver when you only want a quick draft that uses less ink.
Can I change only some pages?
Yes. Type the pages, for example 1-3, 5, and keep the other pages as they are.
Does it work on a password protected PDF?
No. Unlock it first with the Unlock PDF tool.
Is it free?
Yes, this tool is completely free to use.
