PNG keeps transparency. JPG fills transparent areas with white.
The converter opens on Convert to PNG, so each JPG you drop in is saved as a PNG. The pixels the browser decodes from the JPG are written out unchanged, so the save itself adds no quality loss. Whatever compression the JPG already has stays in the picture.
Converting does not restore detail that JPG compression removed. Choose PNG when a program or site asks for it, not to make the picture sharper. A PNG of a small JPG is often larger than the original, and a JPG has no transparency for PNG to keep.
How to convert an image to another format
- Drop one or more images onto the box (or tap it to choose).
- Pick the format you need and, for JPG, WebP or AVIF, the quality.
- Download each file, or all of them as a ZIP.
Questions
Will converting make my blurry JPG sharp?
No. The JPG compression already removed some detail, and a PNG cannot bring that back. The copy keeps the same pixels, so the blur and blocky patches stay.
Why is the PNG so much bigger?
PNG stores every pixel exactly, while JPG throws away detail to save space. Photos with smooth gradients take more room as PNG, so expect a larger file, and compress it another way if a form has a size limit.
Will the images be uploaded?
No. Conversion runs in your browser, so the files stay on your device.
Why does my transparent PNG get a white background as JPG?
JPG has no transparency, so transparent areas are filled with white. Choose PNG or WebP to keep them.
Why is AVIF missing from the list?
AVIF is only offered when your browser can encode it. If it is missing, use JPG, PNG or WebP.
Can it open HEIC photos from an iPhone?
Only if your browser can read HEIC, and many cannot. If a file fails, use the HEIC to JPG tool, which converts it in your browser.
