These Upload Problems Happen All the Time
Here are the three most common causes — and how to spot them.
Wrong File Format
LearnCastAI only accepts PDF and DOCX files. Other formats such as .txt, .pptx, or .odt will be rejected.
Check the file extension in your file manager and convert the file if needed.
File Too Large
The maximum file size is 20 MB. Very large documents or files with embedded images often exceed this limit.
Compress the PDF or split the document into smaller sections before trying again.
Scanned PDF Without Text
A scanned document consists only of images. The AI cannot extract any text and the upload will fail.
Open the PDF and try to select some text with your mouse. If that's not possible, it's an image-only PDF with no searchable text.
3 Steps to a Successful Upload
Work through these steps in order — most problems are resolved after the first or second step.
Check the File Format
Make sure your file is a PDF (.pdf) or Word document (.docx). Other formats are not supported.
Open your file manager and check the file extension. If needed, export the document from your word processor in the correct format.
Check the File Size
Verify that the file size does not exceed 20 MB. Right-click the file and select "Properties" to check.
If the file is too large, compress the PDF with an online tool like ilovepdf.com or smallpdf.com. You can also split the document into smaller parts.
Make Sure the File Contains Text
Open the PDF and try to select a paragraph of text with your mouse. If you can't, the document contains no machine-readable text.
Scanned PDFs can be converted to searchable PDFs using OCR software (Optical Character Recognition). Many online services offer this for free.
More Tips for a Smooth Upload
Sometimes the cause lies elsewhere. Here are more common pitfalls and how to fix them.
Check PDF for Text Content
Open the PDF in your browser or a PDF reader and try to select some text. If that's not possible, the document is an image-only scan.
Use DOCX as an Alternative
If you have trouble with PDF files, save the document as a .docx file (Word format). DOCX files always contain selectable text.
Page Limits by Plan
Depending on your plan, different page count limits apply. Very long documents may need to be split up.
Clear Your Browser Cache
An outdated browser cache can cause upload issues. Clear the cache (Ctrl+Shift+Del) and try uploading again.
Use a Stable Connection
Large files require a stable internet connection. If your Wi-Fi is unstable, try switching to a wired connection or mobile data.
Contact Support
If none of the steps above help, contact our support team. Describe the problem and include the file type and size.
