The Local-First Philosophy

Welcome to Nalas Tools. We believe that basic web utilities shouldn't require you to sacrifice your privacy, view intrusive advertising, or wait in server queues. Traditional online tools force you to upload your files to a third-party server. We took a different approach.

By leveraging WebAssembly (FFmpeg.wasm), our Universal Converter processes images, videos, and audio entirely on your own device — GIF to MP4, WebP to PNG, MP4 to MP3, and hundreds of other combinations. The moment you close this tab, your data is gone.

  • Absolute Privacy. No data is transmitted to our servers.
  • Unrestricted Access. No registration or premium paywalls.
  • Instant Execution. No waiting for server responses.

Professional Grade Output

We designed these tools to bypass the artificial limits common in traditional online generators. When you export a QR code, you receive an ultra-high 1024x1024px PNG or a mathematically perfect vector SVG. When you convert files with the Universal Converter, FFmpeg runs at full quality — the same engine used by professional video studios, running entirely in your browser.

Questions & Answers

Are these tools entirely free?

Yes. Nalas Tools operates without premium tiers, hidden watermarks, or usage quotas. It is designed to be a completely free utility suite.

Why is there no server upload required?

Your modern web browser is incredibly powerful. Instead of uploading your image to convert it, our tool instructs your browser to convert the image locally. This removes server costs on our end, and ensures 100% privacy and speed on your end.

Which image formats do you support?

You can drag and drop WebP, PNG, JPEG, AVIF, and GIF files. Our encoder allows you to batch-convert them into highly optimized WebP, PNG, JPEG, or AVIF formats.

Can the QR Code Generator handle vCards or Emails?

Yes. The generator simply encodes the text you provide. Standard prefixes like mailto: (for emails), tel: (for phone numbers), or raw vCard text blocks will be processed and formatted correctly for mobile scanners.
