- Source images are resized using
coverfit mode, meaning they are cropped to fill each square size. For best results, use a square source image. - When multiple files are uploaded, each gets its own subfolder in the ZIP (named after the source file).
- For a single file upload, all outputs are at the root of the ZIP with no subfolder.
- Files that fail validation or decoding are skipped, and a
skipped-files.txtis included in the ZIP explaining the issues. - Supported input formats: JPEG, PNG, WebP, AVIF, TIFF, GIF, HEIC, SVG, RAW, PSD, and more.
- EXIF orientation is auto-applied before resizing.
