Temperature (Cooler ↔ Warmer)
100% — Neutral

Workflow & Usage

  1. Add your images Drag & drop, paste, or select JPEG/PNG/WebP files. Previews load instantly with correct rotation.

  2. Adjust global temperature Set the main Warm/Cool slider:

    • Below 100% → cooler, more blue/teal
    • Above 100% → warmer, more orange/red
    • 100% → original image temperature

  3. Fine-tune individual images Click Edit to open a modal with per-image temperature control. Adjust until the tones match the look you want.

  4. Include or remove images Toggle Include on each card, delete any photos you don’t want, or reset all values.

  5. Download your results

    • Single export: Click Download under an image.
    • Batch export: Use Download all as ZIP to save all processed files in one archive.

Everything stays on your device — fast, private, and offline-ready.

Use Cases

  • Fix color casts Correct images that look too blue (cool) or too orange (warm).

  • Make consistent photo sets Align product photos or thumbnails to the same warmth level.

  • Improve portraits Warm up skin tones for a healthier, more natural look.

  • Design and branding Create warmer/cooler variants of photos for ads and hero backgrounds.

  • Social media prep Give images a stylistic warm glow or a modern cool tone before posting.

Tips for Best Results

  • Start neutral, adjust gradually. Most warm/cool shifts look good within ±20% of the original.

  • Combine with hue or saturation. After temperature adjustment, refine colors further using the Hue Converter or
    Saturation Converter.

  • Warmer tones are good for people. Skin looks more natural with a bit of warmth.

  • Cooler tones are great for tech or modern designs. They give a clean, minimalist feel.

  • Use ZIP export for bulk edits. Saves time when adjusting large photo sets.

How It Works

  • Canvas warm/cool simulation Temperature is applied using a combination of sepia(), saturate(), and hue-rotate() filters — tuned to mimic photographic warmth and coolness.

  • Original format preserved Exports keep the same mime type and extension (JPEG→JPEG, PNG→PNG, WebP→WebP).

  • Pixel-accurate rendering No scaling or resizing; each image retains its exact resolution.

  • EXIF-aware loading Using createImageBitmap(), photos open with correct orientation.

  • Batch packaging ZIP files are created locally via JSZip, with clean filenames like: photo-temperature-132.jpg.

  • Privacy by design No servers, no uploads, no tracking — just fast, in-browser processing.
