One report instead of five guesses
Debugging a problem image usually means hopping between tools: is the format wrong, is it too heavy, are the dimensions off, is transparency lost, which colours dominate? Each question alone is quick, but together they eat an afternoon when files pile up.
This analysis combines every check into a single table per file: true format, decoded dimensions, friendly file weight, pixel and transparency summary, plus the leading colours with their shares. You see the whole story in one glance and know exactly which fix to apply.
Analysis that respects your privacy
The entire inspection — decoding pixels, counting colours, measuring transparency — runs locally in your browser on your own hardware. Your images are never uploaded, copied to a server, or seen by anyone but you, no matter how sensitive they are.
There is no sign-up and no history: analyze up to ten images, copy what you need, and close the tab with nothing left behind. Only the tool itself may be cached so it works offline; your pictures never are.
When to analyze and what to do next
Analyze mystery downloads, client deliveries, stock shortlists or exports that behave oddly. The colour and transparency rows are especially handy before converting formats, removing backgrounds, or building a design around a photo's palette.
Follow up with Compress image for heavy files, the format converters for wrong types, or Image color palette when you need more swatches. Each tool picks up exactly where this report leaves off.
Questions
Are my files uploaded?
No. The full analysis runs inside your browser on your own device. Your images are never sent to us or to anyone else.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
Which colours are reported?
The three most common opaque colours, grouped into 5-bit buckets to merge near-identical shades. Percentages show each colour's share of all pixels.
Why does transparency show a percentage?
Pixels can be fully transparent, fully opaque, or somewhere between, such as soft shadows. We report the share that is transparent or semi-transparent so you know if alpha data survives.
