If the PDF to Text tool missed important text in the graphics, then run the page again with the Read Text and Image Content option. If a page risk score is medium or high, use the Image tool to examine the graphics content of the page. Use Output Image of Page Graphics to include an image of the page graphics in the tool output. Use Risk Score for Text Encoded as Graphics to provide guidance on whether OCR is necessary to extract all the text on the page. Extraction of text characters only is up to 10x faster than OCR and is generally more accurate.
Read text characters directly from your PDF file. -Please note that this option does not use OCR for extracting text from scanned documents. The addition of OCR provides complete coverage of all text in your file. For files with images of text, use Read Text and Image Content to directly read text characters and apply OCR to the images of text. Images of text require optical character recognition (OCR) to extract the text characters. PDF files might contain a mix of text characters and images of text. The library uses Rollup (easier to setup with Wasm and web workers), while the plugin uses esbuild.Text Extraction Options Read Text and Image Content
#Text extractor from pdf code
Add this type somewhere in your code export type TextExtractorApi = // And use it like this const text = await getTextExtractor ( ) ?. Using Text Extractor as a dependency for your plugin The API functions likely won't change, but this is still a beta. I'm dogfooding this plugin with Omnisearch. This way, other plugins can use it without having to worry about the implementation details, and without having to needlessly consume resources. With this plugin, I hope to provide a unified way to extract texts from images & PDFs, and make it available to other plugins. Text extraction is a useful feature, but it is not easy to implement, and consumes a lot of resources.

You can also install it manually by downloading the latest release from the releases page or by using the BRAT plugin manager. Text Extractor is available on the Obsidian community plugins repository. If not, an empty string will be returned. Since text extraction does not work on mobile, the plugin will use the synced cached texts if available. Those files can be synced between your devices. The plugin caches the extracted texts as local small. Install Java library to extract Text from PDF Import targeted PDF document or render from URL in Java Utilize extractAllText method to extract text from PDF. All the processing is done locally, but the language files needed by the underlying OCR library (Tesseract) are downloaded on demand.
Those libraries are not perfect, and may not work on some files. The plugin currently uses Tesseract.js and pdf-extract to extract texts from images and PDFs.It's mainly useful when used in conjunction with other plugins (like Omnisearch), but you can also use it to quickly extract texts from images & PDFs.
Note: Text Extractor is NOT abandoned! This project provides important features to Omnisearch, and I'll continue to support it with bugfixes, dependencies updates, and maybe quick & small features. You're more than welcome to submit PRs, and I will gladly help and mentor :) I unfortunately can't dedicate much time anymore on Text Extractor, but there are many things that still need to be done: extraction of Excel and Word files, PDF improvements, quality of life features, etc.
