Fix an underwater photo, free

Pick a blue or green dive photo. VividSea's Auto color brings back the reds the water took, right here in your browser. Your photo is never uploaded.

Want more than one photo?

The free tool fixes one photo at a time. The VividSea app does the same Auto color on your phone and adds what the browser can't:

• 50+ underwater looks on top of Auto, with a strength dial (7 are free)
• Video color correction on iPhone for GoPro and phone clips (Pro)
• Batch editing for up to 50 photos at once (Pro)
• Full-resolution saves to Photos that keep the capture date and location

How it works

Water absorbs red light first, so a dive photo's red channel comes out dark and compressed. Auto color looks at your photo's own pixels, rotates the hue just enough to lift the average red to a healthy level, rebuilds the red channel from all three channels, then stretches red, green and blue between the darkest and brightest levels the photo actually uses. The strength slider blends that correction with the original. Read more in the underwater color correction guide.

Common questions

Is my photo uploaded?

No. The photo is opened, corrected and saved by your browser on your own device. Nothing is sent to a server, so it also works offline once the page has loaded.

Is this the same correction as the app?

Yes. It is the same Auto color calculation that VividSea uses in the app, ported to run in the browser: it reads the photo's own pixels, rebuilds the red channel and stretches each color channel.

What does the free tool not do?

It works on one photo at a time and has no looks, no video and no batch editing. The saved JPEG does not keep the original capture date and location. The VividSea app does all of that on your phone.

Which files work?

JPEG and PNG work in every modern browser. HEIC photos from an iPhone open in Safari. Very large photos are saved at up to 16 megapixels so they fit in a phone browser's memory.
