Frequently Asked Questions
For files uploaded directly, we read the size from the file itself. For URLs, we attempt to fetch the Content-Length header using a HEAD request. Access to this header from URLs can be restricted by server CORS policies.
This is usually due to Cross-Origin Resource Sharing (CORS) policies on the server hosting the image URL. If the server doesn't allow our website (or scripts running in your browser from our site) to read headers like Content-Length, we cannot determine the file size. Dimensions, format, and other data might still be available.
Similar to file size, reading EXIF data or analyzing colors from an image URL requires the hosting server to have permissive CORS policies that allow cross-origin access to the image data itself (not just the headers). Many servers restrict this for security reasons. Uploading the image file directly usually bypasses these URL-based CORS limitations for EXIF and color analysis. For more on EXIF, see our article on understanding EXIF data.
EXIF (Exchangeable image file format) data is metadata embedded within image files, typically JPEGs from digital cameras or smartphones. It can include details like camera model, date/time taken, exposure settings (aperture, shutter speed, ISO), focal length, and sometimes GPS location. Not all images contain EXIF data. We have a detailed blog post about EXIF data if you'd like to learn more.
We use the HTML Canvas API to draw the image (or a scaled-down version for performance) and then sample pixel colors from several different areas of the image to provide a representative palette. It's not a complex dominant color algorithm but aims to give a quick overview of the image's tones.
We currently support the following image formats for analysis: JPEG (JPG), PNG, GIF, WebP, BMP, and SVG. Ensure you are providing a direct link to an image file or uploading one of these types.
Direct links to image files (ending in .jpg, .png, etc.) or uploaded image files work best. URLs from hosting services/CDNs are often compatible if they provide direct file access and have suitable CORS policies. Links to web pages containing images will not work for URL analysis.
No. All processing (loading dimensions, reading EXIF, analyzing colors, getting file info) happens entirely within your browser using JavaScript. When using a URL, your browser makes requests directly to the image's server. When uploading, the file is read locally by your browser. No image data is sent to or stored on our servers.
