Pixel color vs. palette
A color picker reports one location. A palette groups or ranks colors from the image, so it is better for themes but not a substitute for exact sampling.
Utility
Pick colors, extract text with OCR, inspect EXIF metadata, compare images, and extract palettes locally.
Quick decision guide
Use an inspection tool before changing the image
Utility tools answer different questions: which pixel or palette color is present, what text can be read, what metadata is embedded, or where two files differ. Choose the diagnostic that matches the decision you need to make next.
| What you need | Start with | Why |
|---|---|---|
| Sample one exact point in an image | Image Color Picker | Click a pixel when you need the displayed color value at a specific coordinate. |
| Find the main colors across the whole image | Color Palette Extractor | Use a palette when you need representative colors rather than one pixel. |
| Copy words from a screenshot or scan | Image to Text (OCR) | OCR estimates characters from pixels; proofread names, numbers, and punctuation. |
| Inspect or remove camera metadata | EXIF Viewer / Remover | Review embedded fields before sharing and create a cleaned copy when needed. |
| Check whether two images changed | Image Diff / Compare | Align comparable files and visualize pixel-level differences. |

How the key settings affect the result
These terms describe different parts of the job. Knowing which one the destination checks prevents unnecessary quality loss.
OCR confidence
Clear, upright, high-contrast text is easier to recognize. Decorative fonts, blur, handwriting, skew, and compression artifacts increase mistakes.
Visible content vs. metadata
EXIF can include camera settings, timestamps, software, orientation, or location when present. Removing it does not remove information visibly drawn into the pixels.
Pixel difference vs. perceived difference
A diff can flag compression noise or a one-pixel shift that people barely notice. Interpret the map in the context of the task.
Alignment
Two images must share dimensions and registration for a clean pixel comparison. Resize or crop changes can make the entire frame appear different.
Decoded color
The value displayed by a browser reflects the decoded image. Color profiles and conversions can make the same asset appear different in another managed workflow.
What you can do in the browser
Inspection and output generation occur on the local device. That is useful for screenshots, scans, and personal photos, but the result is still an aid: proofread OCR, interpret metadata carefully, and visually confirm image differences.
- Sample pixels or extract a representative color palette.
- Recognize text from a supported image and copy the result for editing.
- View available EXIF fields and make a metadata-cleaned sharing copy.
- Compare two aligned images and inspect a visual difference result.
Common failure cases
Check these before downloading or submitting the result.
Treating OCR as a transcript of record
Recognition can silently confuse similar characters. Verify totals, dates, names, and identifiers against the source.
Assuming no displayed EXIF means no sensitive content
Private information may be visible in the image itself, filename, or surrounding document. Review all surfaces before sharing.
Sampling an edge pixel
Anti-aliasing blends foreground and background colors around edges. Sample several interior pixels for a stable design color.
Comparing unaligned files
A crop, scale, or one-pixel translation can dominate the diff. Normalize dimensions and position before interpreting changes.
Removing metadata from the only master
Keep an original with useful capture information and create a separate cleaned copy for distribution.
Complete workflows
Use the tools as a sequence when the destination has more than one requirement.
Extract text from a screenshot
- Crop to the text region and use the clearest available source.
- Run OCR and compare every critical value with the image.
- Paste into an editor, correct line breaks, and save the verified text separately.
Privacy check before sharing
- Inspect EXIF and note any fields you want to retain in the master.
- Create a metadata-cleaned copy.
- Reopen the copy, check metadata again, and inspect the visible pixels for personal information.
Visual regression check
- Export the reference and candidate at identical dimensions.
- Run Image Diff and identify whether changes are global, shifted, or local.
- Review meaningful regions visually instead of treating every highlighted pixel as a defect.
