How to Adjust Photo Shadows

Upload Your Image

Choose an output format (JPEG, PNG, or WebP) and click Save Photo to download at full original resolution.

Why Use This Shadow Adjustment Tool?

  • Full-resolution output – edits are applied to the original image size, not a downscaled preview.
  • HEIC support – iPhone photos in HEIC/HEIF format are automatically converted before editing.
  • Multiple formats – save as JPEG, PNG, or WebP with adjustable quality for JPEG and WebP.
  • Works entirely in your browser – your photos are never uploaded to any server.
  • Shadow-only adjustment – the tool targets dark tones with a quadratic falloff, leaving bright highlights largely untouched.
  • Free & unlimited – no signup, no watermarks, no limits.

Common Uses for Shadow Adjustment

Adjusting shadows is one of the most effective ways to improve a photo’s overall look. Here are some of the most popular reasons people use an online shadow tool:

  • Rescue underexposed photos – brighten dark areas caused by harsh backlighting or insufficient flash.
  • Add depth to flat images – deepen shadows to create a richer, more three-dimensional look.
  • Improve portrait lighting – lift facial shadows for a cleaner, more professional headshot.
  • Prepare images for print – adjust shadow density to ensure details are preserved when printed.
  • Enhance social media photos – make your images pop before posting to Instagram, LinkedIn, or other platforms.

A positive value (up to +100) brightens dark areas of the image, which is useful for recovering detail in underexposed shots. A negative value (down to −100) deepens the shadows, adding contrast and richness to the dark tones. The adjustment is applied with a quadratic falloff so that midtones and highlights are largely unaffected.
Yes. Use the format dropdown above the Save button to choose JPEG, PNG, or WebP. For JPEG and WebP you can also expand the quality setting (the gear icon) to control the compression level from 1% to 100%.
