Yes — upscaling scanned PDFs often improves OCR accuracy dramatically. Try upscaling first, then running OCR.
Large PDFs with many pages can take a few minutes since each page is upscaled individually. Free tier limits to 20 pages per operation.
Upscaling helps most when the PDF is made of images or scans. Text PDFs (where text is vector-based) stay the same since they are already resolution-independent.
