Is Pikkx really free?

Yes! The free tier lets you optimize up to 10 images at a time (5 MB each) with full access to compression, resizing, and format conversion. No credit card, no account required.

Are my images uploaded to a server?

No. All processing happens 100% in your browser using WebAssembly. Your images never leave your device — there are no uploads, no servers, and no third-party access.

What image formats are supported?

Pikkx supports JPEG, PNG, and WebP for both input and output. You can convert between any of these formats while optimizing. AVIF support is coming soon in the Pro tier.

How does the compression work?

Pikkx uses jSquash WebAssembly codecs — the same algorithms used by professional image tools. You control the quality slider to balance file size and visual quality. The processing runs entirely in your browser's Web Worker for fast, non-blocking performance.

What's the maximum file size?

Free tier supports images up to 5 MB each, with up to 10 images at a time. The upcoming Pro tier will support files up to 50 MB and unlimited batch sizes.

Can I resize images for different screen sizes?

Yes. Pikkx includes three built-in viewport presets (mobile, tablet, desktop) so you can generate responsive image variants in one step. Custom viewport sizes are coming in the Pro tier.

Do I need to create an account?

No. Pikkx works instantly with no sign-up, no login, and no tracking. Just drop your images and optimize.

How does this improve my website's performance?

Images are typically the largest assets on a web page and the biggest factor in Core Web Vitals scores like LCP (Largest Contentful Paint). Optimized images load faster, reduce bandwidth, improve SEO rankings, and deliver a better user experience.
