Frequently Asked Questions
What file formats are supported?
You can convert JPG, PNG, WebP, BMP, and TIFF images. The tool preserves the original format of each image whenever possible, so a PNG image stays a PNG.
Can I convert multiple images at once?
Yes! Upload as many images as you want and convert them all in a single operation. When processing multiple images, the results are downloaded as a convenient ZIP file.
Does converting to grayscale reduce file size?
Yes, converting an image to grayscale often slightly reduces its file size because the image no longer needs to store color data (RGB values) for every pixel, only luminance (brightness) values.
💡 Pro Tip
Need to submit physical photo prints? Converting your images to grayscale before printing ensures you have total control over the contrast instead of relying on the printer's default color-to-black conversion settings.
Privacy & Security
Your images are processed securely and automatically deleted from our servers shortly after processing. We never store, share, or analyze your files beyond the conversion operation you requested.
