I'm running this from the root of the documents repository, and I cleaned up the output a tiny bit. The histogram shows us two modes. The smaller mode, around 20 kb, corresponds to files with no images PDF export from Microsoft Word , and the larger mode corresponds to files with images scans of print-outs of the Microsoft Word documents. It looks like about 80 are just text and the other are scans.
This isn't a real histogram, but if we'd used a real one with an interval scale, the outliers would be more obvious. Let's cut off the distribution at kb and look more closely at the unusually large documents that are above that cutoff. You can see it here. It's not a typical public notice; rather, it is a series of scanned documents related to a permit transfer request. Now let's look at some basic properties of the pdf files.
This will give us a basic overview of one file. It might actually be fun to see relate these variables to each other. The main automatic processing that I run on the PDFs is a search for a few identification numbers. I also search for two key paragraphs. My approach is pretty crude. For the PDFs that aren't scans, I just use pdftotext , which is part of poppler-utils.
You can try pdftotext -layout if you need to preserve more of the layout. As we saw earlier, most of the files contain images, so I need to run OCR. Like pdftotext , OCR programs often mess up the page layout, but I don't care because I'm using regular expressions to look for small chunks.
I don't even care whether the images are in order; I just use pdfimages to pull out the images and then tesseract to OCR each image and add that to the text file. This is all in the translate script that I linked above. Try other parsers to extract images and texts:. We've already processed 0 files with total size of 0 Mbyte. When will this app be useful to you? For example, you have been sent a photo album as a PDF document, and you need to extract all the photos in their original format.
The PDF parser application will help you with this task, just open the application page, select the source document and click the extract button.
Your document will be sent to the server, in a moment you will receive an archive containing all the extracted data from your document. Each day, I speak to people who use our tool so I can learn to make it better. Parse a few PDFs and let me know what you think. Convert your first PDF to data. Upload PDF. No credit card required.
