JPG to PNG Converter - Free, Lossless, In Your Browser

Let us be straight about this one: converting a photograph from JPG to PNG will make the file three to five times larger and will not improve it by a single pixel. There are good reasons to do it anyway — they are just narrower than most pages admit, and it is worth knowing whether yours is one of them.

How to convert JPG to PNG

1. 1 Drop your .jpg or .jpeg file onto the upload area.
2. 2 Press Convert — there is nothing to configure, because PNG is lossless.
3. 3 Download the PNG. Note the size shown next to the file name before you commit to it.

It cannot restore what JPG threw away

This is the single most common misunderstanding about the conversion. PNG is lossless, so it stores whatever it is given perfectly — but what it is given is already a JPG, complete with the compression artefacts baked into it. Blocky skies, halos around branches, smeared fine detail: all of it is copied faithfully into the PNG. Lossless means nothing new is lost, not that anything is recovered.

When it genuinely helps

Three cases are worth the extra megabytes. First, editing: if you are about to crop, retouch and re-save an image several times, working in PNG stops each save from adding a fresh layer of JPEG damage. Second, systems that simply demand it — some upload forms, print templates, favicon generators and design tools reject JPG outright. Third, images you intend to cut out: you need an alpha-capable format before you can erase a background, and PNG is the usual choice.

What it will not do for you

It will not add transparency. A converted photo has a fully opaque alpha channel, ready to be edited but not magically cut out — removing the background is a separate task for an image editor. It will not sharpen a blurry shot, undo heavy compression, or increase the resolution. And it will not make the picture better for a website: there the PNG is simply a heavier version of what you already had.
