使い方
使い方
- Choose a JPEG, PNG, or WebP image within the displayed 20 MB and 40 megapixel limits.
- Use hue, saturation, and brightness controls, or switch to RGB channels, while checking the live preview.
- Choose an output format and download the adjusted image when it looks right.
Global color adjustments
HSL mode changes hue, saturation, and brightness across the whole decoded image. RGB mode adds or removes the same amount from each red, green, or blue channel. Values are clamped to valid 0–255 channel ranges.
Clear browser limits
The page accepts one local JPEG, PNG, or WebP up to 20 MB. Decoded images must be no more than 10,000 pixels on either side and 40 megapixels. Canvas output keeps the dimensions but does not retain EXIF, camera metadata, animation, profiles, or other source-file structure.
A focused editor, not a full photo workflow
This tool provides a live global adjustment only. It does not offer masks, selections, layers, curves, histograms, brush edits, batch processing, or local object-aware color replacement. Processing and encoding happen in your browser; nothing is uploaded.
よくある質問
あわせて知りたいこと
What is the difference between HSL and RGB mode?
HSL mode changes the whole image by hue, saturation, and brightness. RGB mode adds or subtracts fixed channel values from every pixel.
Can I recolor only one object?
No. This focused tool applies the selected adjustment globally to every pixel. Use a photo editor with selections or masks for local changes.
Are transparency and metadata preserved?
PNG and WebP can retain transparent pixels. JPEG fills transparent areas with white. Canvas encoding does not retain source metadata or animation.
Does the page upload my image?
No. The image is decoded, adjusted, previewed, and encoded locally in your browser.
