Batch processing for real workflows

Optimizing images one at a time is fine for a single hero image. But when you're processing a product shoot, preparing thumbnails for a catalog, or resizing a batch of photos for a client presentation, you need a tool that handles the volume without making you babysit it.

What each preset does

Web Hero outputs AVIF at quality 70 with a max width of 1920px — ideal for above-the-fold hero images where file size directly impacts your Core Web Vitals score. Thumbnail produces WebP at 400px wide — perfect for product grids and gallery previews. Social / OG creates JPG at exactly 1200×630 pixels — the standard Open Graph size for social media previews. Email-safe outputs JPG at 800px wide and quality 78 — small enough for email clients that choke on large attachments.

Privacy at scale

Every image is processed entirely in your browser. Whether you're optimizing 5 photos or 50, none of them ever leave your device. The ZIP file is assembled client-side too.
