File Converter

What this tool actually does

The File Converter handles the everyday conversions a browser can do natively, without uploading anything. For images it decodes your file with the Canvas API and re-encodes it in the target format — JPG, PNG, WebP, or BMP. For data files it transforms the text directly: JSON can be pretty-printed for reading or minified for shipping, CSV can be extracted to plain text, and messy text can be cleaned up. The options you see adapt to the file you drop in, so you're never offered a conversion that can't work.

A worked example: JSON formatting

Drop in a minified JSON file containing {"name":"ToolsForge","tools":10,"free":true} (44 characters) and choose Pretty JSON. The output — produced by the exact code the tool runs — is:

{
  "name": "ToolsForge",
  "tools": 10,
  "free": true
}

That's 57 characters with two-space indentation, ideal for reading and code review. Minifying reverses the trade: the same data shrinks back to 44 characters for production use. Because the file is parsed before re-output, invalid JSON is caught and reported instead of silently corrupted.

Text cleanup, shown honestly

The TXT (cleaned) option collapses all runs of whitespace — spaces, tabs, line breaks — into single spaces. For example, " Hello world, thi…" becomes "Hello world, this text has chaotic spacing.". That's exactly what you want for text scraped from a PDF or web page, and exactly what you don't want for poetry — the line structure is gone for good.

Image conversions worth knowing about

PNG → JPG is the classic "make this screenshot smaller" conversion, but remember JPG has no transparency: transparent areas are flattened. JPG → WebP typically saves 20–30% at similar quality and is supported by every modern browser. BMP exists mainly for legacy Windows software that insists on it. Lossy targets (JPG, WebP) are encoded at quality 90, a deliberate high-quality default; if you want to choose the compression level yourself, use the Image Compressor instead.
