iAiDoc 灵识文档Images to PDF
All document processing happens locally on your device to protect your privacy.
How it works
Turn JPG, PNG and WebP images into PDF. Detect document boundaries, adjust corners, rotate and correct perspective, then preview seven image effects. Review automatic boundaries before export.
Keep your originals and check page order, boundaries and clarity after export.
Which images and effects are supported?
Use JPG, PNG or WebP. Rotate, adjust corners and perspective, and preview color sharpening, soft color, black-and-white document, grayscale, original enhancement, original grayscale or crop-only.
What if automatic boundaries are wrong?
Move the four corners to the paper edges and review the preview, rotating if needed. Low contrast, occlusion and overlapping sheets can affect detection.
