Frequently asked questions

Are my files uploaded to a server?: No. All image processing runs entirely in your browser on your device. Your files are never uploaded, stored, or transmitted to any server.
Is grayscale the same as black and white?: Yes. Grayscale removes color information, leaving shades from black through white. True black-and-white may also imply high-contrast styling.
Does converting to grayscale reduce file size?: Slightly, because color data is removed, but format and compression settings matter more. Use Compress for significant size reduction.
Can I convert back to color after grayscale?: No. Color information is discarded. Always keep your original color file if you might need it later.
Which photos look best in grayscale?: Portraits, street scenes, and images with strong shapes and textures often excel. Photos that rely on color contrast may look flat without adjustment.
Should I adjust contrast before or after grayscale?: Convert first, then adjust contrast. Desaturation changes how tones relate, so final contrast tweaks are best done on the monochrome result.
What format should I save grayscale images in?: PNG for lossless archival quality, or JPEG at high quality for smaller web-friendly files without transparency needs.
