Compare 96, 150 and 300dpi

Start with 96dpi for quick on-screen viewing or 150dpi for general documents. Try 300dpi when you need to inspect small text or need more pixels, then check the result. It cannot restore details missing from a scan.

Doubling both dimensions produces about four times as many pixels. Compressed file size is different from memory usage. This tool processes one page at a time and caps the longest edge at 4,096px.
