Frequently Asked Questions

What is JPEG 2000?
JPEG 2000 is an advanced image compression standard, created as an improvement over standard JPEG. While it offers superior quality, it is rarely used in common apps today. You might still find these files in older government archives, satellite maps, or specialised medical equipment in hospitals.
Why should I convert JPEG 2000 to JPG?
Standard JPG is the universal format supported by every device—from a basic smartphone in Chennai to a high-end desktop in Bangalore. JPEG 2000 files often won't open on standard gallery apps or email clients. Converting them ensures you can view and share them anywhere without any 'file not supported' errors.
Which browsers support this tool?
Safari typically has native support for JPEG 2000. For Chrome, Edge, and Firefox—which are very popular in India—this tool uses advanced browser scripts to attempt conversion. If the file doesn't open in one browser, you may try another or use Safari if available.
Will I lose image quality?
There may be slight quality loss as JPEG 2000 uses superior compression. However, using our 90-95% quality setting usually results in an image that looks identical to the naked eye while being much easier to share via WhatsApp or email.
Is my data safe?
Absolutely. All conversion happens locally within your browser on your device. No files are sent to our servers. Your data remains completely private and is cleared as soon as you close the tab.
