Good to know
Each page is saved as a grayscale image, so the text in the result cannot be selected. Keep your original if you need to copy text, or run the result through OCR PDF. For scanned paper documents, Scan to PDF has a sharper black-and-white "Document" mode. Need a smaller file as well? Try Compress PDF.
Frequently asked questions
Will the file be smaller?
Often yes for photo-heavy PDFs. Text-only PDFs may become larger because pages are saved as images.
Which quality should I choose?
High (150 DPI) is a good default. Choose Print (300 DPI) for documents you will print at high quality.
Is my PDF uploaded?
No. Conversion happens in your browser.
