Tip: you can Ctrl/Cmd-click to open multiple downloads quickly.

Privacy: Everything runs in your browser. No files are uploaded.
Resize rule: Image is scaled to fit within Max width × Max height while preserving aspect ratio. Leave a limit blank or zero to ignore that dimension.
Quality: Used by JPEG/WEBP only (0..1). PNG ignores quality (lossless by design).
Transparency: JPEG drops alpha; PNG and WEBP preserve transparency.
Metadata: Canvas export strips EXIF/ICC. If you need metadata, keep originals.
Orientation: Most modern browsers decode with EXIF rotation applied. If an image looks rotated, rotate it before processing.
Filenames: Output uses the original name with _resized + new extension.

Edge cases & notes

If both limits are unlimited (0/blank), image is copied to the target format without resizing.
Very large batches may take time and use memory; process in groups for best performance.
Color profiles are not embedded in exports; colors may vary slightly across viewers.
