Choose a PDF task

Use the PDF tools to organize pages, combine documents, or adjust page size. Conversion tools export PDF pages to Word, Excel, PowerPoint, text, or images; supported image and Office files can also be saved as PDFs. Check the relevant guide for the result and its limits.

For example, PDF to PowerPoint makes one image-based slide per PDF page. PDF to Excel extracts supported selectable text and detected tables; scanned image-only pages are not OCR processed.

What Convert Hau Does

Convert Hau provides browser-based image and archive tools, browser-side PDF-to-text and PDF-to-image exports, and server-processed PDF editing, PDF compression, and supported document conversions. Each tool page describes its supported files and the result to expect.

The tool pages identify when a file is sent to Convert Hau's conversion service. Some server jobs use temporary working directories that the application cleans up after processing; this does not establish hosting, infrastructure log, or provider retention behavior.

Supported File Formats

Available formats depend on the selected tool. Image tools cover formats such as PNG, JPG/JPEG, WebP, GIF, BMP, SVG, ICO, and AVIF. Document tools include PDF, DOC/DOCX, PPT/PPTX, XLS/XLSX, and selected text or web formats. Check each tool guide and the format choices shown in the converter before selecting a file.

Some conversions change how content is represented: PDF-to-PowerPoint creates image-based slides, PDF-to-Excel extracts supported selectable text and detected tables, and converting a transparent image to JPG fills transparent areas with white.

Conversion details

For supported document conversions, the server-side service uses LibreOffice. PDF pages use fixed layouts, while editable formats may reflow content; review the downloaded file before relying on it.

Getting Started

To get started, open a tool, choose a file, and select an output format if the tool offers a choice. Start processing, then download and inspect the result. Keep the original until you have checked that the converted file meets your needs.

For detailed guides on specific conversions, check out our Blog section where we cover topics like "How to Convert JPG to PDF," "PNG vs JPG: Which Format Should You Use?", and much more.

File converter questions

Image conversion, archive creation, and PDF-to-text or PDF-to-image exports run in your browser.

        Practical notes for choosing formats and checking converted files. Open the linked tool page for supported inputs, steps, and current limits.

        Turn JPG images into a PDF

        Use Image to PDF when you want a photo or scan in a document that is easy to share or print. Select an image file, run the conversion, and review the PDF page before sending it. This tool creates a separate PDF for each selected image; it does not combine several images into one multi-page document.

        PNG or JPG: which should you choose?

        PNG is useful for graphics, screenshots, and images that need transparent areas. JPG is commonly used for photographs and usually produces smaller files, but it uses lossy compression and cannot keep transparency. Converting a JPG to PNG does not restore detail already lost. See the image conversion guide and inspect the output, especially where transparency or fine text matters.

        What to expect from WebP

        WebP supports lossy and lossless images and can preserve transparency. Whether it is a good choice depends on where the image will be used and which formats that destination accepts. Converting to JPG removes transparency; converting between formats does not guarantee a smaller file. Use the WebP converter and compare the file size and appearance.

        PDF to Word: check the layout

        The PDF-to-Word converter creates a DOCX file for editing. PDF pages use fixed positioning while Word content reflows, so columns, tables, fonts, and page breaks can change. Scanned pages are images and this tool does not promise OCR. Open and proofread the DOCX before relying on it.

        Choose a document format for the job

        PDF is useful when recipients should see a fixed-page layout. DOCX is designed for editing. Keep an editable source document when you expect revisions, and review any exported PDF for fonts, page breaks, and tables. Conversion results depend on the source document and the features it uses.

        About Convert Hau

        Convert Hau provides online tools for images, PDFs, and office documents. Image conversion, archive creation, and PDF-to-text or PDF-to-image exports run in the browser. PDF editing and compression, plus supported document conversions, are sent to the hosted conversion service.

        How the tools work

        Conversion results depend on the source file and the selected task. For example, PDF-to-PowerPoint creates image-based slides, while PDF-to-Excel extracts supported selectable text and detected tables. Each tool guide describes its input, output, and known limitations.

        The frontend uses HTML, CSS, and JavaScript. Browser-based image conversion and PDF preview or image export use browser technologies; supported document conversions use LibreOffice on the server.
