Photograph in good lighting
Even lighting without shadows reduces file complexity, which helps compression. Natural daylight or overhead light gives the cleanest, flattest scan-like appearance.
Enhance contrast before compressing
Open the Photo Editor tool. Increase contrast to +20–30 and increase brightness by 10–15 to make text darker and the background whiter. This pre-processing makes the handwriting more legible and compresses more efficiently.
Crop to the note content only
Remove the desk, background, and any surrounding area using the Crop tool. Cropping to the page content only reduces pixel count and file size before compression.
Resize to 1200px wide
Handwritten note photos display at 800–1200px in most apps. Resize to 1200px wide — enough for legibility of small handwriting without the 4000px overhead of a smartphone photo.
Compress at 80% JPG quality
At 80% JPG quality and 1200px wide, a handwritten notes photo typically compresses to 100–300KB — small enough for any message or email, while keeping all handwriting legible.
