Select a page and tap Adjust page. Saving page adjustments requires Pro.
Choose an adjustment
- Crop trims the page. Drag the corners or edges to set the area you want to keep.
- Correct edges changes the page boundary to correct perspective. Place the corners along the intended page edges.
- Straighten corrects a small tilt. Use the angle slider; the reset button beside it returns this angle to 0°. It does not reset other adjustments.
- Enhance offers Auto enhance, Black & white, Grayscale, and sliders for background whitening, brightness, contrast, and shadows.
Crop and edge adjustments work from the displayed page result, including adjustments you have already made. Review any annotations near the new edges before saving.
Reduce a gray or yellow paper background
In Enhance, increase Whiten background gradually. The lower range is gentler; the upper range cleans more strongly and can reduce a light yellow paper tint.
Watch the page rather than relying only on the slider position. Updating preview… means the preview is still being prepared. Wait for the latest result before judging the setting. Use a lower strength if faint writing, photos, or pale colors lose detail.
Compare and save
Hold Hold to show original to compare with the source image. Release it to return to the adjusted preview. Restore original resets the adjustments; it is different from resetting only the straighten angle.
Use Undo and Redo to review changes, then tap Done to save. If you cancel after changing the page, choose whether to keep editing or discard those changes.
