Facing issue while reading large Scanned PDF file in C#

OCR.space Free OCR API
1

HI
we purchased PRO PDF pack when we tested it with file size more than 100MB we got this response -

The page was not displayed because the request entity is too large.

For purchased PRO PDF, file size is 100 MB+ as per your documentation.

I tried with 57MB file but still getting the same response.

this issue is been escalated to support team but got no response.

here is the code I used for OCR process( work is in c#)

    MultipartFormDataContent form = new MultipartFormDataContent();
form.Add(new StringContent("<<API_KEY>>"), "apikey"); 
form.Add(new StringContent(getSelectedLanguage()), "language");

if (string.IsNullOrEmpty(ImagePath) == false)
{
	byte[] imageData = File.ReadAllBytes(ImagePath);
	form.Add(new ByteArrayContent(imageData, 0, imageData.Length), "image", "image.jpg");
}
else if (string.IsNullOrEmpty(PdfPath) == false)
{
	byte[] imageData = File.ReadAllBytes(PdfPath);
	form.Add(new ByteArrayContent(imageData, 0, imageData.Length), "PDF", "pdf.pdf");
}
HttpResponseMessage response = await httpClient.PostAsync("https://apix.ocr.space/parse/image", form); 
string strContent = await response.Content.ReadAsStringAsync();

This endpoint is especially tuned for uploading large PDF docs.

Hello. I’m also having the same issue but using the free account. I can’t seem to process files larger than 1MB. Can you kindly help?

@misslgd The free OCR plan has indeed a 1MB size limit. The PRO plans do not have this limit.
