The converter tools handle file format transformations that span between the image and PDF categories — tasks where the input and output formats are fundamentally different types of content.

The Word to PDF Converter uses mammoth.js to extract content from .docx files and renders it as a clean document in your browser, then uses the browser's native print-to-PDF function to produce a searchable, text-based PDF rather than an image scan. The Markdown to HTML Converter uses marked.js to process CommonMark and GitHub Flavored Markdown with a live preview panel and a downloadable .html file output — useful for README files, documentation, and blog posts written in Markdown.

The GIF Maker creates animated GIFs from a sequence of uploaded images with adjustable frame delay. The GIF to WebP and WebP to GIF converters handle format switching — animated WebP produces files 50–60% smaller than GIF while maintaining animation smoothness. The Favicon Generator outputs all required icon sizes from a single source image, covering every browser, mobile platform, and PWA requirement in one download.

Frequently Asked Questions

What Word document elements are preserved when converting to PDF?

Headings H1 through H6, bold, italic, underlined text, ordered and unordered lists, tables with borders, hyperlinks, and embedded images are all preserved. Custom fonts are substituted with browser-safe equivalents. Complex multi-column layouts, text boxes, and advanced header and footer designs may not carry through exactly — for pixel-perfect output use Microsoft Word's own Export to PDF function.

What Markdown syntax does the converter support?

CommonMark specification plus GitHub Flavored Markdown extensions including tables, task lists, and strikethrough. Code blocks with language identifiers produce the correct HTML class attributes for syntax highlighting libraries such as Prism.js. Footnotes and LaTeX mathematical notation are not currently supported.

Why use WebP instead of GIF for animations?

Animated WebP uses modern compression algorithms that reduce file sizes by 50–70% compared to GIF, while supporting a full colour palette rather than GIF's 256-colour limit per frame. Most modern browsers and devices support animated WebP. GIF remains the safer choice for email clients and older platforms that have not yet added WebP support.

What favicon sizes should I generate?

The minimum set for modern web use: 16×16 for the browser tab, 32×32 for the bookmarks bar, 180×180 for the Apple Touch Icon on iOS home screens, 192×192 for Android Chrome, and 512×512 for Progressive Web Apps. The Favicon Generator outputs all five plus a 48×48 icon for Windows. Start with a square, high-contrast source image at 512×512 or larger for best results.

Can the Image Collage Maker handle photos with different aspect ratios?

Yes. The collage maker supports 2, 3, and 4-cell grid layouts. Each cell crops and centres its source image to fill the cell proportions automatically. You can adjust the gap between cells and download the final collage as JPG or PNG at a resolution you specify.
