All tools › Read the image
Check the dimensions
Size, ratio, format, colours, transparency and metadata, without changing the file.
It runs entirely in this browser tab: the file you open is never uploaded, and the result is re-encoded from pixels, so its metadata does not come with it.
Settings
- Show the metadata
- What the camera wrote, where the file still carries it.
- Print at
- Three hundred is the figure a print shop quotes. A number from 72 to 1200.
How to use it
- Paste your text into the box above, or open a file.
- Adjust the settings beside it until the result is what you wanted.
- Copy the result, or save it as a file. The result updates as you type.
Questions
- Is my picture uploaded anywhere?
- No. The whole application is carried as WebAssembly and runs on your own device. There is no server to send anything to, and none of these tools makes a network request while it works — not even the one that reads a photograph's location, which is why it gives coordinates rather than drawing a map.
- What happens to the EXIF data?
- It is gone. Every result here is written from pixels, so the camera, the date, the location and the copyright field are all dropped. That is the point of the location tool and a surprise to anybody who wanted the copyright kept, which is why every result says so.
- Is a blur enough to hide something?
- Usually not. A blur and a pixelation are averages of what was there, and both have been reversed in published work by blurring candidate images the same way and comparing. Only a solid fill or noise removes the information, and the tools say which method you chose.
- Why is the example a test pattern rather than a photograph?
- Because this workspace ships no image files anywhere, and a base64 photograph pasted into a source file would be one wearing a disguise. The patterns are drawn from nothing when the button is pressed.
Other tools for read the image
Pick a colour
The colour at a point in every notation, with whether black or white text sits on it.
Extract a palette
The dominant colours, with each one the average of its group rather than a bucket's middle.
Average colour
Averaged in linear light, which is correct, with the ordinary answer beside it for comparison.
Print size and DPI
What the pixels mean on paper, both ways round. It does not write the density field.
Image to Base64
A data URL, a CSS rule or an img element, with what the third it costs actually is.
Image to ASCII
Characters instead of pixels, with the cell counted as twice as tall as it is wide.
Where the photo was taken
Reads the position out of the metadata and hands back a copy without it. No map is fetched.
