Stop Shipping Heavy Assets to Production
Bulk convert PNGs to WebP/AVIF, generate responsive image sets, and crush your LCP scores. No command line, no server uploads, just instant local optimization.
Performance is UX
You spend hours refactoring code to save milliseconds. Don't let a lazy 4MB hero image destroy your Lighthouse score.
Chasing the Green Score.
Largest Contentful Paint (LCP) is the enemy. Unoptimized images are usually the culprit. Batch compress your assets without visible quality loss and watch your Core Web Vitals turn green.
Context Switching Kills Flow.
You are in VS Code. You need a placeholder resized. Do not wait for Photoshop to launch. Do not configure an ImageMagick script. Just drag, drop, and get back to your code block in 30 seconds.
Next-Gen Ready.
Clients send JPEGs. The web needs WebP or AVIF. Convert entire directories of legacy assets into modern, lightweight formats supported by all modern browsers. Future-proof your builds instantly.
Localhost Security.
You're working on unreleased assets. Uploading them to a cloud converter is a security risk. Batch.pics runs entirely in your browser via WebAssembly. The data never leaves your machine, just like a local CLI tool.
The Frontend Toolkit
Generate your `srcset` assets and optimized fallbacks in one pass.
WebP & AVIF Conversion
Drag in a folder of PNGs or JPGs and output next-gen formats. Reduce file weight by 30-50% vs legacy formats for instant bandwidth savings.
Responsive Breakpoints
Need a version at 1920px, 1024px, and 640px for your `picture` tag? Batch resize to specific widths instantly to populate your source sets.
Precision Control
Dial in the exact quality setting (e.g., 80%). Strip metadata to shave off those extra kilobytes. Total control over the output for the performance-obsessed.
Frequently Asked Questions
It's different. CLI tools are great for build pipelines, but for ad-hoc optimization or visual checking, a GUI is faster. Plus, you don't need to remember complex argument flags. Just drag, drop, and done.
Yes, optimizing for web usually means removing unnecessary metadata (EXIF, GPS, etc.) to reduce file size. We handle this automatically to keep your assets lean.
Yes. Transparency is preserved when converting to WebP or resizing PNGs. We ensure your logos and UI elements stay crisp and transparent.
