A fast JPG to PNG converter online that respects your privacy
PNG is a lossless image format that many design apps, websites and editing tools prefer. This JPG to PNG converter online changes your JPG or JPEG files into PNG in moments, so you can keep editing without adding more compression artifacts each time you save.
The conversion is handled by your browser's built-in Canvas engine. Your photos are decoded and re-encoded on your own device, which means they are never uploaded to a server. You can convert one picture or a whole batch and download each result separately.
JPG is great for keeping photo files small, but every save throws away a little more detail. Switching to PNG locks in the image as it is right now, which is ideal before cropping, annotating or layering it in a design. PNG is also the format many online forms, slide tools and print services ask for when they want a clean, predictable file.
There is nothing to configure. Drop your images in and the converter does the rest automatically, showing a preview and the new file size for every picture so you can check the results before saving them.

The PNG keeps the exact width and height of the original JPG, so it drops straight into your layout.

When to change JPG into PNG

- Uploading images to a website, form or print service that only accepts PNG.
- Creating a clean base image before adding text, shapes or a transparent background in a design app.
- Archiving edited pictures so repeated saving does not add more JPEG compression blocks.
- Converting a batch of scanned documents saved as JPG into a format your workflow expects.
Frequently asked questions
Is this JPG to PNG converter free?
Yes. It is completely free, needs no signup and adds no watermark to your converted images.
Will converting JPG to PNG improve quality?
Converting cannot restore detail already lost in the JPG, but PNG prevents any further quality loss when you edit and save again.
Why is my PNG larger than the JPG?
PNG is lossless, so it usually needs more space than a compressed JPG. This is normal and keeps every pixel intact.
Are my images uploaded anywhere?
No. The conversion runs in your browser using the Canvas API, so your images stay on your own device.
Does the converter make the background transparent?
No. JPG files have no transparency, so the PNG keeps the original background. You can remove it later in an editor.
