[POST] /pdf/makesearchable (Scanned PDF to Text Searchable PDF)

This method converts scanned PDF documents (where pages are fully or partially made from scanned images) into a text-searchable pdf. It runs OCR and adds an invisible text layer on top of your document that can be used for text search, text indexing etc.

url required. URL to the source file (PDF, JPG, PNG, TIF, TIFF). Supports links from Google Drive, Dropbox and from built-in PDF.co files storage. For uploading files via API please check Files Upload section. If you are randomly getting Too Many Requests or Access Denied error for your input url, please try to add cache: to enable built-in url caching. You can also encrypt data for output files and decrypt data input files with user-controlled data encryption (uses strong AES encryption with your own keys). Click here to learn more.
httpusername (optional) - http auth user name if required to access source url.
httppassword (optional) - http auth password if required to access source url.
lang optional. Sets language for OCR (text from image) to use for scanned PDF, PNG, JPG documents input when extracting text. Default is “eng”. Other languages are also supported: deu, spa, chi_sim, jpn and many others (full list of supported OCR languages is here. You can also use 2 languages simultaneously like this: eng+deu or jpn+kor (any combination).
pages optional. Comma-separated list of page indices (or ranges) to process. IMPORTANT: the very first page starts at 0 (zero). To set a range use the dash -, for example: 0,2-5,7-. To set a range from index to the last page use range like this: 2- (from page #3 as the index starts at zero and till the of the document). For ALL pages just leave this param empty. Example: 0,2-5,7- means first page, then 3rd page to 6th page, and then the range from 8th (index = 7) page till the end of the document. Must be a String.
password optional. Password of PDF file. Must be a String.
async optional. Runs processing asynchronously. Returns JobId that you may use with /job/check to check state of the background job (possible states: working, failed, aborted and success). Must be one of: true, false.
name optional. File name for generated output. Must be a String.
expiration (optional). Output link expiration in minutes. Default is 60 (i.e. 60 minutes or 1 hour). After this delay generated output file(s) (if any) will be auto-removed from PDF.co temporary files storage. Max allowed expiration period depends on your current subscription plan. To store permanent input files (e.g. re-usable images, pdf, documents), please use PDF.co built-in Files Storage instead.
profiles optional. Must be a String. Use this parameter to set additional configuration for fine tuning and extra options. Explore PDF.co knowledgebase for profile examples.
