Bulk WebP Converter
A tool I built for myself and reach for constantly. Drop in a batch of JPG, JPEG or PNG files and it converts them all to WebP in one go — the modern format that keeps images looking sharp at a fraction of the file size.
It's plain vanilla JavaScript running entirely in your browser. Your images are never uploaded anywhere — the conversion happens on your own machine, so it's fast and private.
What it does
- Batch convert — drag and drop a whole folder of JPG / JPEG / PNG at once.
- Sensible defaults — resizes to a max of 1920×1920 (aspect ratio kept) at around 85% quality.
- See the savings — it reports average file-size reduction and total data saved.
- Download everything — grab every converted file in a single click.
