Convert, resize, rename: by the folder, not the file.
Drop a folder, pick a format, set a max width, name them in a pattern. Walk away with a ZIP. JPEG, PNG, and WebP, all in your browser. No upload, no re-export from Photoshop, no waiting on a tab to spin.
Aspect ratio preserved. Leave blank to keep original size.
Rename Pattern
Tokens: {name}{n}{date}{w}{h}. Leave blank to keep original name.

// 01
Canvas-based encoding
Images are decoded by the browser, drawn to an offscreen canvas, and re-encoded via toBlob(). Quality slider controls JPEG and WebP compression. PNG output is always lossless.
// 02
Smart defaults
JPEG output fills transparency with white (otherwise: black). "Keep original" preserves each file's input format so a mixed batch stays mixed. Skip resize fields to keep original dimensions.
// 03
Naming patterns
Use tokens like {name} (original stem), {n} (1-based index, zero-padded to batch size), {date} (YYYYMMDD), {w}/{h} (output dimensions). Extension is added automatically.
