Choosing an image format
Compare PNG, JPEG, WebP, AVIF, HEIC, TIFF, BMP, and PDF output; understand transparency, quality, resize, and image conversion limits.

Practical file conversion guides
Clear explanations of format choices, conversion steps, and common limitations—so you can choose the right output and keep a reliable copy of your original files.
Vignar’s converters run in your browser. These guides explain what each tool can do and where browser, file-format, or device differences matter. Conversion is not a substitute for checking the result: open exported files in the software and on the devices where you plan to use them.
Documents
Converting text and documents
Choose between Markdown, HTML, plain text, and CSV-to-Markdown table conversion while preserving structure and checking the output.
Data
Working with CSV and structured data
Prepare JSON, CSV, TSV, XML, and YAML for conversion, and avoid common problems with delimiters, quoting, and data types.
PDF
Organizing and merging PDF pages
Reorder, rotate, remove, and combine pages in a browser, with a checklist for reviewing the saved PDF.
Media
Audio and video conversion basics
Understand browser codec support, output formats, trimming, speed, and why a browser may choose a different media codec.
Privacy and file safety
Vignar’s tools are designed to process selected files locally in your browser and do not intentionally upload them to a Vignar server. Keep the original file, avoid processing files you are not authorized to use, and verify important exports. Your hosting provider may still process ordinary connection and security logs. Read the Privacy Policy for details.
Frequently asked questions
Will converting a file overwrite my original?
No. The tool creates a separate download; your selected source file is left as it was. Keep a backup anyway when the file is important.
Why can the same file behave differently in another browser?
Browsers and operating systems ship different decoders and encoders. Some formats use additional browser-loaded codecs, and large files need more memory. See the relevant format guide and try a current desktop browser if a conversion fails.
Does a format name guarantee compatibility?
No. The file extension describes a container or encoding, but software support varies. Open the result in the app that will use it and check its contents before sharing or archiving it.
