How to finish your task
Correct four corners and export an image or PDF. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.
Practical example
Align the four corners of a receipt or document clockwise. Inspect the corrected image and optionally export an image-based PDF.
Scope and limitations
Corners are selected manually. Shadows and blurred text are not restored; use OCR afterward if you need editable text.
Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.
When is this useful?
Correct a photographed document using four corners. Blurred lettering and shadows are not restored.
Input and result example
document photo + four corners → corrected image/PDFExamples illustrate the workflow; actual size, support and recognition depend on the source and settings.
