HOW TO USE

How to use image editing tools

Choose the editing task first—such as cropping, rotation, or color adjustment—then verify the result in the matching tool.
01

Choose the edit

Separate the task into composition, orientation, or brightness and color adjustment.

02

Edit the image

Select the image and adjust it while checking the preview and current settings.

03

Compare and save

Compare the original and edited result, confirm output settings, and download the new file.

EXPERT CATEGORY GUIDE

Core principles of browser image editing

Cropping, rotation, and color adjustment affect coordinates, resampling, re-encoding, transparency, and metadata—not only what appears on screen.

Non-destructive editing

The source file stays unchanged while settings are edited. Export creates a new pixel result, preserving the original.

Crop and aspect ratio

Cropping reduces a coordinate area; a fixed ratio constrains width and height. Smaller crop areas produce fewer output pixels.

Rotation and EXIF orientation

A photo may rely on EXIF orientation. The editor must normalize it before further rotation to avoid double rotation.

Resampling and repeated saves

Rotation and scaling recalculate pixels. Repeated edits and lossy saves can accumulate blur and compression artifacts.

Adjustment differences

Brightness changes overall lightness, contrast changes tonal separation, saturation changes color strength, temperature shifts blue-yellow balance, and sharpness boosts edge contrast.

Transparency and memory

PNG and WebP transparency uses an alpha channel. High-resolution images consume much more memory after decoding, so mobile limits are necessary.
