FAQ
Is this converter really free and offline?
Yes—conversion runs locally in your browser, so your files aren’t uploaded.
Can I convert MP4 to MP3 or change video codecs here?
No. This tool can convert any file to Base64/Data URL/Hex, but true media transcoding needs heavy codecs not included.
What image formats can I convert between?
You can re-encode images to PNG, JPG, or WebP (and optionally resize and set JPG/WebP quality).
How do I embed a file in HTML?
Use File → Data URL, then paste the result into an src attribute (images/video/audio) or CSS.
Can I turn a Base64 string back into a file?
Yes—switch to Text/Base64/Hex/Data URL → File, paste your input, and download the generated file.
Why is the output truncated?
Large outputs can be huge; the tool shows a preview to stay fast. Use Download output text for the full content.
Does it support PDF, DOCX, ZIP, or other documents?
Yes for Base64/Data URL/Hex conversion and decoding back to a file; it doesn’t edit document contents.
