Workflow & Usage

  1. Add images Drag & drop, paste, or click to upload JPEG/PNG/WebP files. Thumbnails appear instantly, using EXIF orientation for correct rotation.

  2. Adjust brightness & contrast Every image starts at a clean 100% brightness and 100% contrast — a neutral baseline that mimics how most cameras capture exposure.

  3. Fine-tune each image Click Edit to open the modal editor.

    • Use sliders to brighten or darken the image
    • Add or remove contrast for more pop or softer tones
    • Reset returns to neutral 100/100

    The preview updates as you drag.

  4. Select your batch Toggle Include per image, remove extras, or reset all to defaults for a consistent starting point.

  5. Export

    • Single file: Click Download to save the edited image in the original format.
    • All files: Use Download all as ZIP to export the whole selection. Filenames include helpful tags like: photo-brightness-120-contrast-80.jpg.

Everything runs fully on-device. No uploads, no logins, no waiting.


Use Cases

  • Fix underexposed or low-light shots Brighten images taken in dim environments without losing detail.

  • Normalize product photos Give your e-commerce catalog a clean, consistent look with matching contrast and exposure.

  • Enhance social content Bring out colors and balance tones before sharing on Instagram, Pinterest, or TikTok.

  • Prepare blog and marketing assets Make graphics cleaner and easier to read without jumping into a full editor.

  • Bulk-correct event or travel photos Drop in your camera roll, adjust, download everything in one ZIP.


Tips for Best Results

  • Start subtle. Increase brightness by small increments (5–10%) to avoid washing out highlights.

  • Use contrast for clarity. Higher contrast makes subjects pop — especially for product photos.

  • Match exposure across sets. For consistent grids or listings, apply similar brightness/contrast levels to every image.

  • Reset if you go too far. The Reset button instantly brings the image back to the neutral 100/100 baseline.

  • Export in original format. JPEG for photos, PNG/WebP for graphics or transparency.

  • Pair with compression. After adjusting, use Image Compressor or Progressive JPEG Converter to reduce file size for the web.


How It Works

  • Canvas filtering. Images load via createImageBitmap({ imageOrientation: 'from-image' }) to ensure correct rotation. Adjustments use the browser’s high-quality Canvas filtering and image smoothing.

  • True full-resolution export. While previews are scaled for speed, exports are generated at the original resolution — preserving sharpness and detail.

  • Neutral baseline. Brightness and contrast start at 100% each, equivalent to zero change. You adjust relative to the original pixels.

  • Batch ZIP packaging. Selected images render client-side and are packaged into a ZIP using JSZip, ready for one-click download.

  • Privacy by design. No servers, no uploads, and no tracking of your images — everything stays on your device.
