ScanPDF是什么？
ScanPDF.online is a free tool that converts PDF files into PDFs with a scanned look, eliminating the hassle of printing and then scanning. Its advantages are: data is processed locally to protect privacy; it uses WebAssembly technology for fast processing, completing in just seconds, with real-time preview of settings; and it supports offline use without relying on the internet.
ScanPDF功能特点：
Fast and efficient: Greatly saves the time spent preparing and processing with traditional scanners, quickly generating scanned copies. Ideal for situations that require quickly producing large numbers of scanned copies, like mock exam papers in education, archiving old documents in office settings, and creating vintage looks in design.
Quickly generates a scanned effect: No need to print and scan — just a few clicks and you get a scanned-looking PDF.
Versatile effects: Simulates natural paper creases, fading, and noise to produce highly realistic scanned copies. It also offers different paper types such as regular paper, kraft paper, and old newsprint, as well as scanning modes with high or low resolution.
Privacy and security: Data stays on your own device and is not stored on servers; all processing is completed in the browser.
Fast processing: Based on WebAssembly technology, the scanned PDF effect is produced instantly with one click.
Customizable settings: For each different process, all parameters can be previewed in real time so you can achieve the effect you want.
Offline use: Offline processing is also supported, so it works normally even without a network.
