COLOR ACCURACY GUIDE

Image Color Profile Guide

Two files can look identical on one screen and noticeably different on another. Color profiles and how each format stores them explain much of that gap, especially after you convert or re-encode an image.

What color profiles and ICC data are

A color profile (often an ICC profile) tells software how to translate stored pixel values into colors on a specific display or printer. sRGB is the usual default for web photos and UI graphics; Adobe RGB and Display P3 cover wider gamuts common in cameras and modern phones.

JPG and JPEG often embed a profile in EXIF or APP2 markers. PNG can store an iCCP chunk. WEBP and AVIF may carry profile-related metadata depending on how the file was created. Viewers that ignore the profile still show an image, but they may assume sRGB and shift hues or saturation.

Why colors can shift after conversion

Conversion usually decodes pixels in the browser, then encodes a new file. That path may keep an embedded profile, replace it with a default, or drop profile data while leaving pixel values unchanged. Each choice changes how the next app interprets the same numbers.

Lossy formats such as JPG re-sample color data, which can soften reds, greens, or skin tones even when the profile is preserved. Moving between wide-gamut sources and sRGB targets without explicit color management can make exports look dull or oversaturated on different monitors.

JPG, PNG, WEBP, and AVIF in practice

JPG to PNG or PNG to JPG is a common handoff step. PNG is lossless for pixels but does not magically fix a missing profile; if the source was interpreted wrong, the PNG copy inherits that look. Re-saving JPG at lower quality can change colors more than the format change itself.

PNG to WEBP and WEBP to PNG are popular for web performance. WEBP encoding may not carry the same metadata layout as your PNG editor exported. AVIF can look excellent at small sizes, but aggressive compression and profile handling vary by encoder, so compare against your PNG or JPG reference before you ship hero images.

Web and ecommerce checklist before publishing

Open the final file on the monitor you care about, then on a phone or second display if customers use both. Check product reds, neutral grays, and skin tones against your source, not only file size.

When a marketplace or CMS asks for sRGB JPG, convert from your master, avoid unnecessary extra re-encodes, and keep an archived original. Use local conversion when you do not want files uploaded to third-party servers during tests.

Limits and what browser conversion can do

ImageConvert runs conversion in your browser. It is built for practical format changes and everyday quality settings, not a full color-management studio with soft-proofing for every printer profile.

Some outputs may retain display-related chunks; others may flatten to what the browser canvas exports. Always verify important brand colors on the converted file. If metadata removal is part of your workflow, remember that stripping EXIF can also remove embedded profiles, which changes how downstream tools read the image.

  • Remove EXIF - Strip metadata locally; note that embedded ICC color profiles in EXIF may be removed too, which changes how other apps interpret colors.
