Frequently Asked Questions
Why convert JPG to PNG?
PNG uses lossless compression — ideal for logos, screenshots, and images where every pixel detail matters.
Will converting to PNG increase file size?
Typically yes. PNG files are larger than JPEG because they store full colour data without applying lossy compression.
Does JPG to PNG conversion add transparency?
No. JPEG images have no transparency channel. The resulting PNG will have a solid background matching the original JPEG.
Is my image uploaded to a server?
No. Everything runs 100% in your browser — your files never leave your device.
Is this tool free?
Yes. Completely free with no sign-up, no watermarks, and no usage limits.
What JPEG files are supported?
Any standard .jpg or .jpeg file up to 20 MB is supported.
