Image Viewer

Downloaded a WebP, AVIF or HEIC picture that your computer refuses to open, or a TIFF, PSD or icon file with no program to view it? Drop it here. The viewer shows the image and its key facts — format, pixel size, aspect ratio, file size, transparency and animation — and can save a JPG or PNG copy that opens anywhere. Formats the browser cannot decode itself, such as TIFF or PSD, are converted on your device by a built-in image engine. Nothing is uploaded.

How to use this tool

1. Choose or drop one or more image files.
2. Optionally pick “Also save a copy as” JPG or PNG.
3. Keep the image engine on for TIFF, PSD, TGA and other uncommon formats.
4. Look at the previews and the details table.
5. Download the copies, or all files as a ZIP.

Formula

aspect ratio = width ÷ gcd(width, height) : height ÷ gcd(width, height); megapixels = width × height ÷ 1,000,000

The format is identified from the first bytes of the file (its “magic number”), not from the file name, so a misnamed .jpg that is really a WebP is reported correctly. Transparency is measured on a copy of up to 512 px; animation is read from the file structure (GIF frames, the WebP animation flag, the APNG acTL chunk).

Example

A 4032 × 3024 HEIC photo from an iPhone is reported as HEIC, 4032 × 3024 px, 12.19 MP, 4:3. With “save a copy as JPG” you get a 4032 × 3024 JPG that Windows Photos, email and any website accept.
