Prepare your launch assets
Resize a listing image. Export a WebP.
Fit your screenshot, logo or campaign image inside a chosen size, then compare the actual export before using it in your listing.
The tool reads and processes your selected image locally. It does not upload the file or save it to an account. Ordinary site analytics may record this page visit.
PNG, JPEG or static WebP. Up to 10 MiB, 6 million pixels and 8,192 pixels per side. Animated images and SVG are not supported.
Fits inside both dimensions without cropping or enlarging. Quality controls the encoder; it is not a visual-quality score. A smaller file is not guaranteed.
A listing-image example
A 2,400 × 1,200 screenshot fitted inside 1,200 × 630 becomes 1,200 × 600. The whole image remains visible. A 320 × 160 logo stays 320 × 160 because enlarging it cannot recover detail.
Start at 80% quality. Inspect small text and edges in the actual output, then lower the setting if the result still reads clearly. The measured file size may increase for an already optimized source.
Check the destination requirements
This preserves aspect ratio; it does not crop or add padding to force an exact social-card shape. Check the destination’s accepted formats, aspect ratio and file-size limit. A WebP export is not a promise that every directory accepts it.
The browser re-encodes pixels, so original metadata and color profiles may change. Keep your original. This tool supports static images only and does not inspect accessibility, licensing or whether text remains readable.
