Is this an AI photo editor?

No — every adjustment is a standard, documented per-pixel formula (brightness offset, contrast scaling around mid-gray, saturation blending toward luma), the same category of math behind familiar CSS and Instagram-style filters, not a machine-learning model.

Can I combine a preset with the sliders?

Yes — brightness, contrast and saturation apply first, then the selected preset (grayscale/sepia/invert) applies on top of that result.

What file format does the edited photo download as?

A JPEG, which keeps the file size reasonable for a photo; use the watermark tool or background remover instead if you specifically need a PNG with transparency.

Is my photo uploaded anywhere?

No — every adjustment runs entirely in your browser via the Canvas API; nothing is uploaded to a server.

Why does increasing contrast make dark areas darker, not lighter?

Contrast scales each pixel's distance from mid-gray (128) — a pixel already darker than mid-gray moves further from it (darker), while a pixel lighter than mid-gray moves further the other way (lighter), which is the standard definition of a contrast adjustment.

Can I undo just one slider without resetting everything?

Drag that slider back to 0 (or the preset back to "None") — Reset is a shortcut for resetting all of them at once, but each control is otherwise independent.

Free tool — real filters, not AI

Photo editor online

This photo editor online applies real Canvas-based adjustments — brightness, contrast and saturation sliders, plus one-click grayscale, sepia and invert presets — running entirely in your browser. Every effect is a standard, well-documented per-pixel image-processing formula (the same math behind familiar CSS/Instagram-style filters), not an AI-powered "smart" enhancement.

How to use the photo editor

Upload a photo. Choose any JPEG, PNG or WebP image to edit.
Try a one-click preset (optional). Grayscale, Sepia or Invert apply instantly and can be combined with the sliders below.
Adjust brightness, contrast and saturation. Drag each slider to see the change applied live in the preview.
Reset if needed. Click Reset to return every slider and preset to its default, unedited state.
Download the result. Download saves the edited image as a real JPEG file.

Worked examples

Brightening an underexposed photo

Setting brightness to +30 lifts every pixel's RGB values by roughly 77 (30% of 255), visibly lightening a dark photo without altering its contrast or color balance.

A real grayscale conversion

The Grayscale preset uses the standard ITU-R BT.601 luma weights (29.9% red, 58.7% green, 11.4% blue) to compute each pixel's brightness — the same formula broadcast television uses to derive a black-and-white signal from color.
