Turn colour photos into smooth shades of gray or pure black and white. Works on JPG, PNG, WebP, HEIC, AVIF, GIF, BMP, SVG, ICO or TIFF images, one or a batch.
Work on one photo or a batch. Edit in editor opens one original photo separately.
Switching to the editor opens originals on separate pages. Each page is edited individually, with no Apply to all pages. Batch settings and results stay separate from editor edits. Switching back restores each mode's session until reload.
Export one editor page or all pages as a ZIP. Save project keeps editable layers and embedded original image bytes, including original metadata. Exported images are rebuilt from pixels and do not retain that metadata.
Shades of gray keeps smooth tones between black and white, which works well for photos. Black & white uses only those two colours, which can help with simple drawings or high-contrast scans. It can lose faint details; compare the result before saving.
A pixel darker than the threshold becomes black; the rest becomes white. Start at 128, then raise it for more black or lower it for more white. The threshold is only used in Black & white mode. Save as PNG or lossless WebP for exactly two colours; JPG compression can add gray pixels near edges.
Yes, the conversion keeps transparent and partly transparent pixels. PNG and WebP preserve them by default. JPG fills transparent areas with white; add Format to choose the background colour.
Yes. Add up to 20 files, with 20 MB per file and 100 MB total. In Batch, the same mode and threshold apply to every image. In Interactive Editor, each page has its own grayscale settings and reset. Downloads get a -grayscale suffix so they are easy to tell apart from the originals.
Yes. Add Grayscale Image to an image workflow, choose the mode, then Preview or Run. You can chain it with Crop, Resize, Compress, Image to PDF or other compatible steps and save the workflow settings for later.
No. Conversion and comparison happen in your browser. Keep the tab open until you download your images; reloading clears the batch. Website hosting and performance measurement are described in our Privacy notice.
