JPG to PNG Converter

Convert JPG images to PNG for free, entirely in your browser. PNG is lossless and supports transparency, which makes it the right choice for graphics, logos and any image you plan to keep editing.

When this conversion makes sense

There are two good reasons to turn a JPG into a PNG, and one common bad one.

• You need transparency. JPG cannot store an alpha channel at all. If you are about to cut out a background or place the image over a coloured layout, you need PNG.
• You are going to edit it repeatedly. Every time you re-save a JPG it loses a little more detail. PNG is lossless, so you can save it a hundred times with no degradation. Convert first, edit, then export back to JPG at the end.
• You think it will improve quality. It will not. See below.

Expect the file to get much bigger

PNG compresses by finding repeated patterns, which works beautifully on flat colour and terribly on photographic noise. A 400 KB photographic JPG commonly becomes a 3–4 MB PNG. That is normal and not a sign anything went wrong.

Notice the reversal on the last two rows: for graphics and screenshots PNG is genuinely smaller as well as sharper. The format comparison guide explains why.

How to convert

1. Drag your JPG file into the box above, or click to browse. Multiple files at once is fine.
2. Confirm PNG is selected as the output format.
3. Adjust the quality slider if the format is lossy.
4. Click Convert, then download the PNG files individually or as a single ZIP.

Does converting JPG to PNG improve the quality?

No. PNG is lossless, so it stops any further degradation from happening — but it cannot undo what JPG already discarded. Convert to PNG to protect an image going forward, not to repair one.

Will the background become transparent?

No. PNG supports transparency but converting does not create it — the background stays exactly as it was. To actually remove it, use the Background Remover and export as PNG.

Why is my PNG ten times larger?

Because PNG stores every pixel exactly and photographs have no repeating patterns to compress. This is inherent to the format, not a settings problem.

Should I upload PNG to an exam or government form?

Almost never — those portals overwhelmingly require JPEG. Converting to PNG for a form upload will get it rejected. See the form photo guide.
