One stack, repeatable results
Brightness, contrast, saturation, temperature, blur, sharpening, pixelation, vignette and grain stay visible as numbers. A preset is a starting point, not a hidden black box.

Build a look, not just a one-click filter
Start from a crafted preset, then tune every ingredient while a true before/after split keeps the edit honest.

Export the finished image
The source and every rendered pixel stay in this browser. No request contains your image.
Judge the edit against its source
The split preview aligns original and result pixel for pixel. For stricter QA, send both full-resolution images straight into the five-mode comparison lab.
Export the finished image
Render at the original dimensions and choose JPEG, PNG, WebP or AVIF. The result can continue to compression without downloading and selecting it again.
Before you start
Effects get reached for in two very different moods. One is corrective: a photo is too dark, too flat or too blue, and you want it to look like what you remember seeing. The other is stylistic: you want the image to carry a mood it did not have. The controls are the same either way, but the stopping point is not, and most over-edited images are corrective work that kept going after it was finished.
What catches people out
Every save of a JPEG costs you a little
Editing a JPEG decodes it, changes it and re-encodes it, and the re-encode loses detail whether or not you changed much. Do all your adjustments in one pass rather than saving between each one, and keep the original file.
Raising contrast throws away the ends first
Pushing contrast clips highlights to pure white and shadows to pure black, and clipped detail cannot be brought back by lowering it again. If the image will be edited further, leave headroom at both ends.
Screens disagree about what you just did
A warm grade on a cool monitor looks neutral, and a subtle shadow lift disappears on a phone in daylight. If the image has a known destination, judge it there rather than on the screen you happen to be editing on.
