02 Good to know
The browser applies Canvas filters and saves a PNG. Transparency is preserved; source metadata is not copied.
03Adjust brightness, contrast and saturation
Brightness changes overall lightness, contrast changes separation between lighter and darker areas, and saturation changes color intensity. Move one control at a time and compare the preview with the source.
The available range is 0% to 200%. A high setting can clip highlights or shadows and make colors look unnatural, so check the result before sharing it.
04Choose a format for the adjusted copy
The browser applies Canvas filters and re-encodes the image. Under More options, keep the source format or choose PNG, JPG, WebP, or AVIF. Transparency is retained by formats that support it; source metadata is not copied. Keep the original if you may need its unadjusted pixels.
