1. QR Code Generator – Create Custom QR Codes Easily
Sharing a long website address, Wi-Fi details, contact information, or a social media profile can be inconvenient when people have to type everything manually.

Toolstwenty’s QR Code Generator helps you create QR codes for everyday, personal, and professional use. Select the type of information you want to share, enter the relevant details, customize the design, preview the result, and download the finished code in a supported format.
What can you create with this QR code tool?
Customize the QR code to match your brand
A QR code does not always need to look plain and generic. Depending on the available design options, you can customize colours, use gradients, adjust dot and corner styles, add a logo, choose a frame, and review the live preview before exporting your code.
The tool provides PNG, JPEG, and SVG export options. PNG and JPEG are useful for many everyday digital uses, while SVG can be useful when you need a scalable graphic for compatible design and print workflows.

Large image files can be difficult to upload, email, share, or store. They can also increase the amount of data a browser needs to load when those images appear on a website.

Have you ever needed to send several scanned pages, receipts, screenshots, or photographs as one document? Attaching every image separately can make a collection harder to organize and review. Converting supported images into a single PDF can make them easier to share, store, and open as one document.
Toolstwenty’s Image to PDF Converter lets you select multiple JPG, JPEG, and PNG images and combine them into one PDF document. You can review the selected images and adjust available page, orientation, and compression settings before creating the PDF.
What can this image-to-PDF tool help you do?
Add a watermark when needed
The converter also provides an optional text watermark with an opacity setting. This can be useful when preparing a document that needs a visible label, such as a draft or reference copy. Remember that a watermark is not a substitute for proper access controls or document security.

YouTube thumbnails give viewers a quick idea of what a video is about before they watch it. Creators, bloggers, and designers may want to inspect thumbnail designs, compare image quality, or save a thumbnail for permitted reference and workflow purposes. Finding the correct image manually can take extra time.
Toolstwenty’s YouTube Thumbnail Downloader lets you enter a supported public YouTube video link or video ID to preview the thumbnail versions available for that video. You can then download an available image or copy its direct image URL.

An image may look perfectly fine but still be the wrong size for a website, social media profile, video thumbnail, banner, or online form. Some platforms require specific pixel dimensions, while others work better with square, portrait, or landscape images. Changing dimensions without care can also stretch or distort the original image.

Choose the resizing method that fits your task
