Universal file converter
How to convert a file
Universal file converter is a free tool that changes a file from one format to another in your browser, for images, PDF, Word, Markdown, HTML, audio, video, subtitles and data, without uploading it.
- 1. Add a file
Drop a file on the box, or click it to select one. You convert one file at a time, up to 1 GB.
- 2. Select the format
Select the output in Convert to Format. The list shows only the formats that this type of file can become. For JPEG and WebP, you can also set the quality.
- 3. Convert
Click Convert Now. To turn a PDF into text, the tool reads each page, so a long PDF takes more time.
- 4. Download
Click Download to save the result. Click Clear to start again with a different file.
Frequently asked questions
Are my files uploaded?
No. The conversion runs in your browser, on your own device, and the file is not sent to our server. To turn a PDF into Word, text, Markdown or HTML, the page first downloads an open-source text reader (OCR) and its Vietnamese and English language data from jsDelivr and tessdata.projectnaptha.com; your PDF is not sent to them.
Is it free? Is there a limit?
It is free, with no account and no daily limit, because your own device does the work. Each file can be up to 1 GB, and you convert one file at a time.
Which conversions can it do?
An image becomes PNG, JPEG, WebP, BMP, an ICO icon with 16, 32, 48 and 256 px pictures (only the sizes that your image is big enough for; the image keeps its shape, with a transparent border), a one-page PDF or Base64 text; JPEG, BMP and PDF cannot keep transparency, so a transparent background becomes white. A PDF becomes Word, text, Markdown, HTML, or an image of its first page. A Word .docx file becomes PDF, HTML, text or Markdown, a Markdown file becomes PDF, Word, HTML or text, and an HTML page becomes PDF, Word, Markdown or text. Between Word, Markdown and HTML, the headings, bold and italic text, links, lists and tables stay. Audio becomes WAV, a video gives its sound as WAV or one frame as PNG or JPG, SRT and VTT subtitles become each other, and CSV and JSON become each other. A CSV file can use commas or semicolons, and a cell in double quotes can hold a comma or a line break.
Does Word, Markdown or HTML to PDF keep all of the text?
Yes. The tool puts all of the text on as many A4 pages as it needs, with headings, lists, quotes and line breaks, in your device’s own font, so accented letters, Vietnamese included, come out right. Each page is saved as a picture of the text, so you cannot select or search the text in the PDF. Images, the original fonts and the page layout are not kept, and a table becomes rows of text.
Does PDF to Word keep the layout?
No. The tool takes the text of each page, also from scanned pages with text recognition (OCR) in Vietnamese and English, and puts it in an editable Word file as paragraphs. Tables, images, columns and fonts are not kept, so check the text before you use it.
Can it convert a video to MP4, or audio to MP3?
No. From a video it takes only the sound as WAV or one frame as an image, and audio becomes WAV. To turn a MOV or WebM video into MP4, use Compress video: it always saves MP4.
Can it open HEIC or TIFF photos and animated GIFs?
HEIC and TIFF depend on your browser, because the tool opens an image with the browser’s own image reader. Chrome and Edge cannot read either, so the tool tells you so and offers only Base64 there: Base64 copies the file’s bytes as they are and needs no reading of the picture. For any other format, save the picture as JPEG or PNG first. For HEIC on an iPhone, select Settings › Camera › Formats › Most Compatible for new photos, or export the photo as JPEG from the Photos app. For TIFF, open it in Preview (Mac) or Paint (Windows) and save a copy as PNG or JPEG. An animated GIF opens, but PNG, JPEG, WebP, BMP, ICO and PDF are still images, so they keep only its first frame. Base64 keeps the file as it is, with every frame.
Why did the conversion fail?
The file can be damaged, protected with a password, or in a format that your browser cannot read (a HEIC or TIFF photo in Chrome can only become Base64); save it in a common format, such as JPEG or PDF, and try again. An old Word .doc file is refused with a message: open it in Word, LibreOffice or Google Docs and save it as .docx first.
