Frequently asked questions

How do I make a photo black and white online?

Upload the photo and click the Black and white preset, or drag the grayscale slider to 100 percent. Adjust contrast to taste, then choose a format and download. The edit happens in your browser and the original file is not modified.

Which adjustments does the image filter tool offer?

You can adjust brightness, contrast, saturation, grayscale, sepia, blur, hue rotation and invert, and start from presets such as Black and white, Vintage, Vivid, Cool and Faded. The preview updates live as you move each slider.

How do I add a sepia or vintage effect to a picture?

Choose the Vintage preset, or raise the sepia slider and lower contrast slightly while adding a little brightness. Sepia gives the warm brown tone associated with old photographs. Reset returns every slider to its default.

Are the filters applied to the downloaded file, not just the preview?

Yes. The download applies the same settings at the image original resolution. Some browsers, notably Safari, use a slower fallback that may not render blur or hue changes identically, so open the exported file to check the result.

What format should I export filtered images in?

Use PNG for full quality, JPEG for smaller photo files or WebP for the best size on websites. The tool saves JPEG and WebP at a fixed high quality. If you export JPEG, any transparent areas are filled white.

Can I undo a filter or go back to the original?

Yes. Click the Original preset or the reset button to set every slider back to its default. Your source file is never overwritten, because the tool downloads a separate edited copy with the word filtered added to the file name.

Is my data shared when using the Image Filters?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the Image Filters?

No, this tool is 100% free. There are no limits, sign-ups, subscriptions, or hidden charges required.

How do I reduce image sizes without losing transparency?

Export your image as WebP or PNG format. Standard JPEG format does not support transparent layers and will convert transparency to white.
