Frequently asked questions
How do I convert an image to PDF free?
Open ScanTo, choose Scan to PDF, add your images, set quality, and download the PDF.
Is there a file size limit?
Limits come from your browser memory. For large batches, use fewer pages or lower quality.
Can I convert PNG to PDF without losing quality?
Use higher JPEG quality in the slider, or page size "match image" for less downscaling.
