FAQ
Will converting to PNG improve the quality?
No. It stops further loss but cannot undo what is already there. The compression artefacts in the JPG are now simply part of the image, and PNG reproduces them exactly.
Why did the file get so much bigger?
PNG is lossless, so it must store real information about every pixel. Photographs have no two identical neighbours and compress badly under those rules, while JPG got its small size by discarding detail. Several times larger is normal.
Does the PNG gain transparency?
It gains the ability to store it, but nothing becomes transparent by itself — the JPG had no transparency to recover. You would need an editor to remove a background afterwards.
When is this conversion actually the right move?
Before editing, when you plan to save repeatedly; when a tool or upload form insists on PNG; and when you need an exact pixel-level copy for comparison or archiving. For simply publishing a photo on the web, the JPG was already the better format.
What happens to EXIF and GPS data?
It is dropped. The conversion goes through the browser's canvas, which does not carry metadata across — so camera details and location are stripped, and the orientation tag is applied to the pixels rather than preserved as a tag.
How fast is it?
Effectively instant. This runs on the image decoder built into your browser rather than on a downloaded engine, so there is nothing to fetch before the first conversion.
Is it really free?
Yes — every conversion on this site, with no account, no watermark and no daily cap. The work happens on your own device, so there is no server bill for us to pass on to you.
Do I need to install anything?
No. It runs in any modern browser, on Windows, macOS, Linux, Android and iOS. There is nothing to download and nothing to sign up for, and once the page has loaded it keeps working with the network switched off.
