Frequently asked questions
How do I convert my files?
Choose or drop your files, adjust the options if you like, then press “Convert” and download the result.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser, so your files never leave your device — safe for private photos and documents.
Is there a file size limit?
There is no fixed limit. Very large files (hundreds of MB) depend on your device's memory and can be slow on phones.
Is it free?
Yes — free and unlimited, with no sign-up and no watermark.
About the formats
JSON
JSON is the text format web APIs and apps use to exchange data. It stores lists and objects as names and values, and is easy for programs to read.
CSV
CSV is a plain-text table: one row per line, with the values separated by commas or semicolons. Every spreadsheet, database and programming language can read it.
