JPG to PNG Converter FAQ
Do I need to create an account?
No, you can use this tool immediately without signing up or logging in.
Is my data secure and private?
Yes, all processing happens directly in your browser, so no data is ever sent to our servers.
Does it work offline?
Once the page is loaded, the core logic works offline since it runs locally in your browser.
Does converting add transparency?
No. PNG supports transparency, but your JPG source contains none, so every pixel stays fully opaque after conversion.
Will the file get bigger?
Usually yes. PNG is lossless and uncompressed compared to JPG, so converted photos are often noticeably larger.
How is it different from similar tools?
Everything runs entirely in your browser as local JavaScript - there is no account step and nothing is uploaded.
What is the technical working principle?
It uses the HTML5 Canvas API to draw the JPG image and export it as a lossless PNG blob at the original dimensions.
What is a common use case?
Graphic designers use it daily to convert standard photos into PNG format to prepare them for further editing and transparency removal.
