Frequently Asked Questions
How do I straighten a skewed document photo?
Upload your photo, and our interactive 4-corner mesh will automatically detect or allow you to drag the four corners of your document to fix perspective distortion and flatten the image.
What are the document enhancement filters?
You can choose between 'Magic Scan (B&W High Contrast)' which turns grey backgrounds into pure white and sharpens text, 'Grayscale', or 'Original Color'.
Does this tool support strict file size limits (KB / MB)?
Yes! You can select a target file size (e.g., under 100 KB, 200 KB, or 500 KB), and our automated binary search compressor will optimize the output file precisely.
Does the output file contain 300 DPI print metadata?
Yes. Our binary encoder injects verified 300 DPI JFIF density tags directly into the JPEG stream, making scans fully compliant with official submission portals.
Are my scanned identity documents saved on any server?
No. All perspective transformations, contrast enhancements, and compression run 100% locally inside your browser memory (RAM) with complete privacy.
