How it works

How to convert an image to grayscale

  1. Choose photos, a whole folder, or drop them on the page.
  2. Pick a look and set the strength; the preview shows before and after.
  3. Save each photo, or all of them as a ZIP.

Black and white, sepia and vintage photo filters

Classic, soft and high-contrast black and white, a red-filter look, noir, sepia and duotone sit next to colour looks such as film, vintage, warm, golden, teal and orange, matte and moody.

Filter many photos at once, at full resolution

Drop a whole folder: every photo gets the same look and strength and is saved at full size with its EXIF data, one by one or as a ZIP.

Grayscale converter: Questions

What is the difference between grayscale and black and white?

Grayscale keeps every tone as a shade of grey from the photo's brightness. A black and white look also changes how colours turn into greys and adds contrast, like a print. Both are here; Soft is the neutral grayscale.

Can I make the filter weaker?

Yes. The strength slider mixes the look with the original, from 0 % (unchanged) to 100 % (the full look), and the preview follows right away.

Is the photo saved at full quality?

Yes. The effect runs on the full-resolution pixels and the photo is saved at high quality (JPG 90 by default, or PNG / WebP). The date, camera data and colour profile are kept, and the photo is turned the right way up.

Can I do hundreds of files at once?

Yes. Drop a whole folder or select as many files as you like. They are processed a few at a time on all your processor cores, with progress for every file. You can pause, stop, retry, and save as a ZIP or straight into a folder.

Are my photos uploaded anywhere?

No. FotoJock runs entirely in your browser: the files are read, converted and saved on your own phone or computer. Nothing is sent to a server, and it keeps working offline once the page is open.

Is it really free?

Yes, with no account, no watermark and no limit on the number of files. FotoJock is made by Foto Jocković, a photo shop in Belgrade.
