🖼️ Image Tools
Check image width, height, aspect ratio, megapixels, format, and file size instantly.
Inspect the basic technical dimensions of a JPEG, PNG, or WebP image without uploading it or modifying the source file.
Inspect an image's decoded width, height, aspect ratio, file type, and byte size without uploading it. This is useful before submitting an image to a site with exact dimension requirements.
The selected image is decoded and processed in the browser. Keep the original until the downloaded output has been opened and checked on the target device.
Last reviewed for accuracy:
Scenario: A site requests at least 1200 × 630 pixels and the selected image decodes as 1730 × 909.
Result: The image exceeds both minimum dimensions and has an aspect ratio close to 1.90:1.
The browser reports intrinsic decoded pixel dimensions; dividing 1730 by 909 yields approximately 1.903.
File metadata supplies byte size and declared type, while actual image decoding confirms pixel dimensions. A successful decoder check is more trustworthy than relying on the filename extension alone.
No. This tool only reads browser-visible dimensions and file metadata; it does not rewrite or upload the source file.
No. Print size also depends on the chosen pixel density and layout. Pixel dimensions describe the digital raster itself.
