Is my data uploaded to your servers?

No. Conversions happen locally in your browser, so your files stay on your device.

Which formats do you support?

Converters include JSON, CSV, XML, Excel (XLSX), Base64, and common image formats.

Can I convert both directions (for example JSON to CSV and CSV to JSON)?

Yes. Several converters work both ways, including JSON⇄CSV and JSON⇄XML.

Why does my JSON fail to convert to CSV?

Nested objects/arrays and inconsistent keys can cause issues. Try flattening or selecting a consistent structure before converting.

Is there a file size limit?

There is no hard limit, but very large files may be slower because processing runs in your browser.

Will converting change my data values?

The goal is to preserve values, but formatting differences (dates, decimals, escaping) can vary between formats.

Can I convert images to Base64 for embedding in code?

Yes. Use Image to Base64 to generate a Base64 string for HTML/CSS/JSON or API payloads.

Does Image Compressor reduce quality?

Compression aims to reduce file size while keeping good visual quality, but extreme compression can reduce detail.
