NAPS2 is free and open source scanning software for Windows, Mac and Linux.

Easily scan with devices from Canon, Brother, HP, Epson, Fujitsu, and more. Then save to PDF, TIFF, JPEG, or PNG with a single click.

Use the best drivers for your scanner

Choose between WIA and TWAIN drivers, whichever works better for your scanner. Also choose settings like DPI, page size, and bit depth. Scan from a flatbed or automatic document feeder (ADF), including duplex support.

Rotate, crop, and rearrange images

Drag and drop your pages into whatever order you like. Interleave pages for manual duplex scanning. Rotate your pages by hand or automatically deskew to the right angle. Use image editing tools to crop or change brightness and contrast.
