Photo & document essentials / 12
Make a photographed or scanned page easier to read. Lighten the paper, bring out the ink, and compare the result before you download.
Use an evenly lit image of light paper with darker writing. Crop the edges or correct rotation first with Crop & Rotate. A sharp source helps more than a strong filter.
Increase paper lightening to reduce gray backgrounds, then adjust brightness and contrast. Keep Color mode for colored annotations or stamps. Grayscale removes color; Black & white turns every pixel into black or white.
For example, lighten a photographed receipt while checking that pale price digits remain legible. Reset if the settings remove detail. Export PNG or JPEG and inspect the full-size result before sharing.
Paper lightening estimates a local average brightness and brightens pixels relative to it. It can help with light gray paper or mild uneven lighting. Deep shadows, colored paper, creases, photographs and dense printing may need different settings or a better source photo.
Not always. Strong lightening, contrast and threshold settings can remove pale details or change colors. Start with Color mode and gentle settings. Keep an unchanged original; cleanup is not a way to authenticate or restore a document.
This tool accepts one JPEG, PNG or WebP image. Use PDF to Images first, then clean the exported pages individually. Use Images to PDF to combine cleaned images afterward. It does not create searchable text.
Yes, it keeps the browser-oriented source pixel dimensions. Transparent areas become white and source metadata is discarded. Browser image density tags may differ from the original. Use Dimensions & DPI Checker for print-size estimates.
Input is limited to 20 MiB, 24 megapixels and 12,000 px per side; encoded output is capped at 60 MiB. Preview cleanup has a 15-second worker limit and full export a 60-second budget. Large images can use substantial browser memory; try a smaller image if needed.
Use Tab to reach controls and arrow keys on each slider. New settings replace pending preview work. Cancel terminates active pixel processing; an in-flight browser decode or image encode must finish before its data is released. Changed settings invalidate previous downloads.
