Fill transparency with white

Why convert JPG to PNG?

JPG (JPEG) is a lossy format built for photographs — it squeezes file size by throwing away detail, and it cannot store transparency. PNG is lossless, so every pixel is preserved exactly, and it supports an alpha channel for see-through backgrounds. Converting a JPG to PNG is the right move when you need clean edges for a logo, a screenshot, a graphic with text, or an image you plan to edit repeatedly without the quality loss that stacks up each time a JPG is re-saved.

How the conversion works

This tool draws your image onto an HTML canvas and re-encodes it as a PNG using your browser's own image engine. Because a JPG has already discarded some data, converting to PNG will not magically restore lost detail — but it locks in the current quality with no further loss, and gives you a format that most editors, print shops, and design tools treat as the gold standard. You can also tick "Fill transparency with white" for source formats like WEBP or GIF that carry an alpha channel you want flattened.

How to use it

Click the file box and choose one or more images — JPG, WEBP, GIF, BMP, or others your browser can read.
Optionally check "Fill transparency with white" if you want a solid background instead of a transparent one.
Wait a moment while each image is converted on the spot — a preview appears for every file.
Click "Download PNG" under any thumbnail to save it. Use "Clear" to start over.

FAQ

Are my images uploaded to a server?: No. Everything happens inside your browser using JavaScript and canvas. Your files never leave your device, so it is completely private.
Can I convert many images at once?: Yes. Select multiple files and each one is converted and offered as a separate PNG download. Batch conversion is fully supported.
Will the PNG look better than the JPG?: It will look identical to the current JPG. PNG is lossless, so it preserves what is there, but it cannot recover detail the original JPG compression already removed.
Why is my PNG larger than the JPG?: PNG stores every pixel without lossy compression, so photos often end up bigger. That extra size is the trade-off for perfect, editable quality.
