Adjust Light & Color
Adjust Light & Color hands you the exposure and color sliders that actually matter, with a press-and-hold compare so you can judge each move against the original.
How to adjust the light and color of a photo
- 1
Open your photo
Drag an image in, paste it from your clipboard, or click to browse for a file. It loads right away and stays on your device — nothing is sent anywhere.
- 2
Fix the light first
Set overall lightness with exposure or brightness, then add a touch of contrast to restore depth. The preview updates as you drag each slider.
- 3
Tune the color
Use vibrance for richer color that spares skin tones, saturation for an even boost, temperature to correct warm or cool white balance, and tint to fix a green or magenta cast.
- 4
Check it against the original
Press and hold the eye button (or the \ key) to see the untouched photo, release to see your edit. Nudge any slider that went too far, or reset one back to zero.

Download your result
Export as PNG, JPG, WebP or AVIF and pick the quality you want — free, no watermark, no sign-up.
Why use PicStudio for this?
Some photos are 90 percent there. The portrait is sharp but the room was dim. The product looks fine but flat against the white backdrop. The sunset you remember as orange came out gray-blue. This is the tool for that last 10 percent: seven sliders — exposure, brightness, contrast, saturation, vibrance, temperature and tint — instead of a preset that decides everything for you and gives you no say in the result.
Fine-tune brightness, contrast, saturation, warmth & more.
Every slider redraws the image as you drag it, and holding the compare button (the eye in the top bar, or the \ key) snaps back to the untouched original for as long as you hold it, so you can confirm you actually improved the shot rather than just made it different. The work happens in your browser using a canvas in the page itself, which means the file is processed on your device and never uploaded — no progress bar, no account, no watermark, and no copy of your photo sitting on someone's server.
Order matters more than people expect. Get the overall lightness right with exposure or brightness first, then add a small amount of contrast to put the depth back. For color, reach for vibrance before saturation: vibrance leaves already-strong colors and skin tones alone, so faces don't turn orange when you push it. Temperature is your white-balance fix — warm up a photo shot under cold fluorescent light, or cool down the yellow cast of a tungsten bulb. Tint is the last resort, there to kill a faint green or magenta shift the temperature slider can't reach.
When the look is right, export to whatever the destination needs: PNG for screenshots and graphics with hard edges, JPG for photos headed to email or a feed, WebP when you want the smallest file at the same visible quality. Nothing locks you in afterward — crop it, drop a filter on top, sharpen the eyes, or compress the result, all in the same session without sending the image anywhere.

Frequently asked questions
Is the Adjust Light & Color tool free?
Yes, fully. There's no sign-up, no watermark on your export, and no cap on how many photos you adjust.
Are my images uploaded to a server?
No. The adjustments run on a canvas inside your browser, so the photo is processed on your own device and never leaves it. Nothing is uploaded or stored.
When should I use vibrance instead of saturation?
Use vibrance when you want muted colors to come up without overcooking the rest. It protects already-strong colors and skin tones, which keeps portraits looking natural. Saturation pushes every color equally and is better for graphics or when you want a deliberate, punchy effect.
What's the difference between temperature and tint?
Temperature slides the image between warm orange and cool blue, which is how you correct a white balance that was off. Tint handles the other axis — green versus magenta — for the slight color cast that temperature alone can't remove.
Will adjusting lower my image quality?
The edits are applied at full resolution, so the picture itself isn't downscaled. The only thing that changes file size is the format and quality you choose at export time.
What formats can I open and save?
You can open JPG, PNG, WebP and HEIC files, and export your edited photo as PNG, JPG, WebP or AVIF.
Does it work on my phone?
Yes. The sliders and the press-and-hold compare are touch-friendly and responsive, so adjusting a photo works on phones and tablets as well as on a laptop.
