How to use Cool Filter a PNG
- 1. Upload your PNG. Add the photo you want to give a cooler mood, such as photo.png. Portraits, landscapes and product shots all respond well to a blue-green color shift.
- 2. Set the coolness level. Drag Coolness (%) to control how strongly the image shifts toward blue and green tones, from a barely-there tint to a heavy, wintry color cast.
- 3. Download the filtered PNG. Save the resulting image, which is shifted toward cool tones, and use it wherever a calmer, colder color mood fits the photo better than the original.
When to use Cool Filter a PNG
Cool Filter a PNG shifts the image balance toward blue and green tones, giving a photo a colder, calmer mood without touching its composition. Cool Filter a PNG works entirely in your browser and suits quick color grading passes where opening a full photo editor would be overkill.
- Grading a winter-themed photo set. A photographer preparing images for a winter campaign wants a consistent cool color mood applied across a batch of otherwise neutral outdoor shots.
- Matching a brand's cool color palette. A social media manager posting product photos for a brand built around blue and teal tones shifts each image toward cooler colors to match the feed's look.
- Toning down a warm, orange-tinted photo. Someone with a photo that came out too warm from indoor lighting applies a cool shift to bring the color temperature back to something more neutral.

You can shape the output with the Coolness (%) setting, and the result refreshes the moment you change it.
