A tool to make PDFs look scanned.
Technical Positioning
A privacy-focused, high-quality alternative to online "make my PDF look scanned" tools, offering local processing via CLI or browser (WASM) to avoid file uploads and produce realistic output.
SaaS Insight & Market Implications
This tool addresses a clear user pain point: the privacy and quality concerns associated with online PDF manipulation services. By offering local processing via CLI or WebAssembly in the browser, it eliminates the need to upload sensitive documents to third-party servers, a significant security and trust advantage. The focus on "realistic" output also differentiates it from existing solutions, indicating a commitment to quality that users often seek in document processing. While seemingly a niche utility, the underlying principle of local, secure, and high-fidelity document transformation has broad appeal across various business functions, particularly where document authenticity or privacy is paramount. This highlights a market demand for robust, client-side solutions over potentially insecure cloud alternatives.

Show HN: Make PDFs look scanned (CLI or in the browser via WASM)
I made this because the online "make my PDF look scanned" tools want you to upload your file to their servers, which feels sketchy at best. Also, I wasn't happy with the output they produce, I wanted something that looks realistic.
Developer Debate & Comments
It's pretty good, but there seem to be some similar products on the market that can convert locally without uploading.
This has been working for mehttps://lookscanned.io/en/scan
Basically, you’re converting it to an image-based PDF so they cannot just scrape the text off of it but would have to use OCR?
But… does it look scanned? https://i.imgur.com/ENKZV7s.png
I just display the PDF on my monitor and use my phone to take a photo of it. Scanner apps are good at eliminating moire patterns while accentuating the dust on my monitor. It looks highly realistic.
In the example image, the edge gradient bevels give it away.There might be extra stuff that can be done to remedy that with this tool, but I'm not sure I'd ever use this anyway.
Is there any good tool that does the opposite — turning scanned documents into clean PDFs? I’ve had that need recently.
I'm having a similar use case from time to time, I just use imagemagickmagick -density 150 input.pdf \ -colorspace Gray \ -virtual-pixel White -background White \ -rotate 0.7 +repage \ -attenuate 0.45 +noise Gaussian \ -blur 0x0.4 \ -brightness-contrast -5x12 \ -compress jpeg -quality 78 scanned.pdf
If you’re interested in another suggestion: maybe allow image output too since that seems to be one of the steps in your pipeline? Maybe for some people using the jpg or a png directly is better than the final pdf.
I’m all for fun side projects, so don’t take this the wrong way. Does this have a practical use case? Like are people actually wanting to make their PDFs less legible? Usually I’m trying to do the opposite, clean up my scanned-in documents.
