Convert Image to PNG

First, the thing worth knowing before you convert

Converting a JPG to PNG does not improve the image, and a lot of people do it expecting exactly that.

JPEG compression is lossy, and the detail it discarded is gone. The soft blocks in a sky, the grey halos around text, the smeared fine detail — those are not a property of the file format, they are baked into the pixels themselves. Converting to PNG stores those same pixels, artifacts included, without losing anything further. It preserves the damage perfectly.

And the file usually gets much larger. PNG is lossless, which for a photograph typically means three to five times the size of the JPG you started with — same picture, bigger file. If your goal was a better-looking or smaller image, this conversion gives you neither.

The only way to get a genuinely better version is to go back to the original — the camera file, the RAW, the export before it was saved as a JPG.

When converting to PNG is the right call

There are good reasons, and they are all about what happens next rather than about improving what you have.

You are about to edit it repeatedly. This is the strongest reason. Every time a JPEG is saved it is re-compressed, so editing and saving a JPG several times compounds the damage visibly. Convert to PNG first and use that as your working copy: the edits stop costing quality. Export back to JPG once, at the end.

You need to add transparency. A JPG has no transparency to preserve — that is not what this does — but PNG can store it. So converting first means you can then cut out a background, round the corners, or drop the image onto a coloured layout without a white box around it.

Something requires PNG. Plenty of systems do: certain print workflows, some app icon and asset pipelines, upload forms that reject JPG, tools that expect a lossless input.

The image has sharp edges. Screenshots, diagrams, logos, anything containing text. PNG is the right home for these, and keeping them as PNG from here on stops further degradation — though it cannot undo what the JPEG already did.

Why there are no settings

Deliberate, and worth a sentence. PNG compression is lossless, so quality is not a variable — every PNG of the same image looks identical and only the encoder's efficiency differs slightly. A quality slider on a PNG converter would be meaningless, so there isn't one. If a converter offers you one, it is doing something other than what it says.

Transparency is preserved for any source that has it, which matters if you are converting WebP or GIF files rather than JPGs.

Several at once

Add multiple files and each is converted with its own download row; two or more come back as a single ZIP. Everything happens in the page, so screenshots, documents and personal photos are not uploaded anywhere to have their container changed.

Convert Image to JPG goes the other way, which is the more common need — and the page explains when that is a good idea and when it is not. Convert Image to WebP is usually the better modern choice if the goal is a small file for the web, since WebP supports transparency at a fraction of PNG's size, and Compress Image reduces file size without changing format.
