Is my data secure when converting files?

Many conversions are processed locally in your browser, so your files can stay on your device during the conversion.

Which formats are supported?

This collection includes converters for JSON, CSV, XML, Excel (XLSX), Base64, images, and text-to-PDF.

Is there a file size limit?

There is no fixed hard limit, but large files may be slower because your browser does the work.

Can I convert multiple files at once?

Most tools process one file at a time. Some workflows can be repeated quickly for multiple files.

Why does JSON to CSV fail for nested JSON?

Nested arrays/objects may need flattening or a consistent structure to map cleanly into CSV columns.

Will converting change my data values?

Values are preserved where possible, but formatting differences (dates, decimals, escaping) can vary between formats.

Can I convert images to Base64 for code?

Yes. Image to Base64 creates a Base64 string you can embed in HTML/CSS or send in API requests.

Does image compression reduce quality?

Compression reduces file size while aiming to keep good visual quality, but very high compression can reduce detail.
