Available tools
QR Code Generator
Create custom QR codes — free, forever.
Most QR code generators online force you to sign up, show ads, or watermark your result. Nalas Tools' QR code generator is completely free with no limits. Every code is generated entirely in your browser using the Canvas API — no data is ever sent to a server.
- 6 dot pattern styles: Square, Dots, Rounded, Classy, Classy Rounded, Extra Rounded

- Works with URLs, plain text, phone numbers, email addresses and more
- Live preview updates instantly as you type
Image Converter
Convert WebP, PNG, JPG & AVIF instantly.
Converting images traditionally means uploading them to a third-party server — which raises privacy concerns and is often slow. Nalas Tools converts everything locally using the HTML5 Canvas API. Your images are processed at full speed right inside your browser.
- Supports WebP, PNG, JPEG, AVIF and GIF as input
- Convert to WebP, PNG, JPEG or AVIF with adjustable quality
- Drag-and-drop multiple images and convert them all at once
- Download all converted files as a single ZIP with one click
- 100% private — your images never leave your device
Frequently asked questions
Everything you need to know about Nalas Tools and how it works.
Are all tools really free?
Yes — every tool on Nalas Tools is completely free. There are no hidden fees, no premium tiers, no watermarks and no ads. The tools run entirely in your browser, so there's no server cost on our end for processing your files.
Do I need to create an account?
No. Nalas Tools requires no account, no email and no registration of any kind. Open the tool you need and start using it immediately.
Is my data private? Are files uploaded to a server?
Your files and data are never uploaded to any server. Everything — QR code generation, image conversion — happens entirely within your browser using JavaScript and the HTML5 Canvas API. The moment you close the tab, nothing is retained anywhere.
What image formats does the Image Converter support?
You can upload WebP, PNG, JPEG, AVIF and GIF files. As output you can choose between WebP, PNG, JPEG and AVIF. You can also adjust the quality level for lossy formats like JPEG and WebP.
Can I generate QR codes for things other than URLs?
Yes. The QR Code Generator works with any text input — URLs, plain text, phone numbers (use the tel: prefix), email addresses (mailto:), Wi-Fi credentials and more. Any text that fits within QR code data limits can be encoded.
What's the difference between PNG and SVG export for QR codes?
PNG is a raster image format — ideal for web usage, social media and quick sharing. ToolHub exports PNG at 1024×1024 pixels for excellent clarity. SVG is a vector format, meaning it scales to any size without loss of quality — ideal for printing on large materials like posters, banners or merchandise.
