Frequently Asked Questions
Learn how local file conversion works, why an output can be larger, which browsers and formats are supported, and how to retry a failed conversion.
Can I convert files now?
Image, PDF, document and data tools marked Working can process supported files locally. Check browser requirements and limits on each tool page.
Will I need an account or subscription?
The working tools are free to use and require no signup. Conversions add no watermark.
Will files be sent to a server?
Conversion runs in browser memory. The website loads code and static libraries, and the converter code has no file-upload service. Reset clears selected files and results from the workspace. Your browser handles downloads and memory disposal.
Can I convert Word documents?
Word to PDF is currently unavailable and marked Coming soon. It does not accept DOC or DOCX files. TXT to PDF is available for supported plain-text files.
Which browsers and file sizes are supported?
Image tools test the browser’s native decoder and encoder. Each converter describes its accepted formats and file, page or table limits.
Why is the converted file larger?
Format changes can trade smaller size for compatibility or lossless pixel encoding. A PNG from a JPEG often uses more space. Compare the actual result size and use the JPG or WebP quality controls when lossy compression suits your task.
Can conversion restore image detail or Word layout?
A new format cannot restore detail already missing from the source. PDF page tools copy ordinary page content with documented losses of interactive features. TXT and Markdown exports follow their own font and structure limits. Read the output notes on the chosen tool page.
How can I retry a failed conversion?
Read the error, then choose a supported file or adjust the settings and convert again. For PDF rendering errors, select fewer pages or lower the DPI. Reset releases temporary results and lets you start over.
Are there advertisements?
