Preview

Drop a photo to preview Original vs Adjusted. Zero upload. No AI cloud.

How it works

Four steps from drop to download. Nothing is uploaded. Preview updates live as you drag.

  1. 1

    Drop or paste

    Add JPG, PNG, WebP, HEIC, GIF, or AVIF. One photo or a batch. Paste from the clipboard when you need speed.

  2. 2

    Drag the sliders

    Tune Brightness, Contrast, and Saturation. Use Low, Balanced, or High, or reset one slider with the icon after it.

  3. 3

    Compare live

    Original and Adjusted update as you drag. There is no separate Preview button.

  4. 4

    Download under Preview

    Pick Original, JPEG, PNG, or WebP. Download one file or a ZIP. JPG, PNG, and WebP can still carry location tags.

Frequently Asked Questions

Honest answers about what each slider does, edit order, export, and privacy.

What do Brightness, Contrast, and Saturation do?

Brightness lifts or darkens the whole photo. Contrast stretches lights and darks so the image looks punchier or flatter. Saturation boosts or mutes color strength. Each slider runs from -100 to +100 with Low, Balanced, and High presets.

What order should I edit in?

Set Brightness and Contrast first. Then move Saturation. Color is easier to judge after the light looks right.

Does export strip EXIF?

No. JPG, PNG, and WebP downloads can still carry location and camera tags. The warning sits at the top of Preview. Remove EXIF Data opens with this photo already loaded. HEIC, GIF, and AVIF do not keep those tags in the new file.

Can I adjust HEIC from my iPhone?

Yes. HEIC is accepted. If this browser cannot read the file, convert it with HEIC to JPG first. The photo stays on this device.

Can I adjust many photos at once?

Yes. Add several photos. The same sliders apply to every included photo. Download All ZIP packs them together.

Do my photos get uploaded or run through AI?

No. Adjustments run in your browser. Your photo is not sent to a NixRey server. The page may load normal app/runtime code like any website. That is app/runtime code, not an upload of your image. There is no cloud AI enhance.
