Image Dimensions Reader
Drop any image to see its dimensions, aspect ratio, file size, and detected format. Works for JPG, PNG, WebP, AVIF, GIF, SVG. Image stays in your browser — nothing uploads.
How to use the Image Dimensions Reader
Drop or pick an image file. The tool reads the file metadata locally and shows width/height/ratio plus file size and MIME type. For SVG it also extracts the viewBox.
Reading image dimensions and metadata
Before you place an image in a layout, size a thumbnail, or debug why one looks stretched, you need its real numbers: pixel width and height, aspect ratio, file size, and format. Opening a full editor just to read those is overkill.
Drop a file here and the tool reads it locally, reporting dimensions, aspect ratio, file size, and detected MIME type for JPG, PNG, WebP, AVIF, GIF, and SVG — and for SVG it pulls the viewBox too. Nothing uploads. Once you know the size, shrink it with the image compressor or strip its metadata with the metadata stripper.
Common use cases
- Layout planning — get exact dimensions before placing an image.
- Aspect-ratio checks — confirm a crop matches the target ratio.
- Debugging display — find why an image appears stretched or blurry.
- Asset auditing — read format and file size at a glance.
- SVG inspection — extract the viewBox from a vector file.
