Straighten artwork, homework, notes, and document photos. Clean the background, preserve paper texture, and save a new photo. All processing stays on your device. Description Happy Lens is a lightweight local photo cleanup tool for artwork, homework, handwritten pages, notes, and document photos. When you take a quick photo of a paper sheet or artwork, the image is often tilted, uneven, shadowed, or surrounded by a messy background. Some scanner apps also process images too heavily, losing color, paper texture, and real brush or pencil details. Happy Lens focuses on one photo at a time, making the cleanup flow simple and fast. Choose a photo from your library, and Happy Lens will detect the main paper or artwork area, crop the edges, and correct perspective so the result looks more straight and natural. If automatic detection is not perfect, you can manually drag the four corners to adjust the frame. Key features: Detect artwork or document edges automatically Adjust the four-corner frame by hand Correct perspective for tilted photos Artwork mode to preserve texture, color, and brush details Ink Wash mode for soft ink tones and paper highlights Document mode for cleaner pages and clearer lines Fine-tune brightness, contrast, and background cleanup Press and hold to compare with the original photo Export results as new photos without replacing the original Happy Lens does not require an account and does not rely on cloud processing. Your image processing stays on your device, and your photos are not uploaded to a server. Great for: Children’s drawings, crafts, homework, and practice sheets Classroom handouts, paper notices, handwritten notes, and sketches Artwork, ink wash, calligraphy, and document photos taken at an angle Turning a quick photo into a cleaner image for saving or sharing Happy Lens is not a complex scanning, OCR, or file management app. It is a quiet, focused tool for straightening one photo, cleaning the background, preserving the original feel, and saving the result back to Photos.
