What each adjustment does

AdjustmentEffectUse it when
BrightnessLightens or darkens everythingDark indoor photo
ContrastPushes lights and darks apartDull or hazy image
SaturationColor intensityFaded colors, or black and white at -100
ExposureMultiplies light, in stops (EV)Under- or overexposure
TemperatureBlue or orange castFix yellow indoor lighting
VignetteDarkens the cornersDraw the eye to the center

\[ \text{exposure} + 1 \, \text{EV} = \text{light} \times 2 \]

Tip: several small moves (10 to 30) look more natural than one big one.

Filters, crop, frames and text

The 15 filters are combinations of adjustments (for example "Vintage" = partial sepia, lower saturation, vignette and a warm tint). A strength slider mixes them from 0 to 100%, and your manual settings stack on top.

  • Crop: 1:1, 4:5, 4:3, 16:9 or 9:16 with zoom and position, plus 90° rotation and mirror.
  • Text: an automatic outline keeps it readable on any background; drag it anywhere.
  • Stickers: 16 emoji you can place and resize.
  • Frames: white, black, Polaroid, rounded or double line, in any color.

Undo, compare, save

Every action is remembered: Undo and Redo walk through up to 60 steps. "Before/after" overlays the original on your edit with a comparison slider.

The saved file keeps your photo's resolution up to 4,096 pixels on the longest side. All processing happens in your browser: nothing is uploaded, no copy is kept, and metadata such as GPS location is not carried over.

3 real-life examples

1

Rescue a dark photo

A birthday picture taken indoors is dim. Exposure +0.8, contrast +15, temperature +10: faces come forward without blowing out.

2

A square post for Instagram

Crop to 1:1, apply the "Pop" filter at 70%, add "Summer 2026" in white with an outline, then a thin white frame. Export as JPG.

3

A retro look

"Vintage" filter at 100%, vignette +20 and a Polaroid frame: your family photo looks like an old album page.

Frequently asked questions

How can I edit a photo online for free?
Drop your photo, drag the adjustment sliders or pick a filter, add text or a frame if you like, then download. No sign-up is needed.
Are my photos uploaded to a server?
No. Every edit is calculated in your browser and the photo stays on your device.
Can I undo a change?
Yes. Undo and Redo walk through your last 60 actions, and "Reset" brings back the original photo.
Does saving lower the quality?
Not with PNG. JPG and WebP use 92% compression, which is almost invisible. Images are capped at 4,096 px on the longest side.
How do I compare before and after?
Turn on "Before/after" and move the slider: the left side shows the original photo, the right side your edited version.
