图像 OCR 和 PDF OCR 有不同的工作

Use image to text OCR when you need editable text from a screenshot, photo, scan, or image-based PDF. The result is plain text that is easy to copy, paste, search, and save as TXT.

Use scanned PDF to searchable PDF when you need the file to remain a PDF. The output keeps the original page look and adds a hidden text layer for search and text selection.

Both OCR modes start processing immediately after upload on a compatible worker and keep the requested output at full quality.
