Will converting to PNG improve my image quality?

No — and no tool can. The detail lost to the original JPG compression is gone permanently. What PNG gives you is a guarantee of no further loss from here on.

Why is my PNG so much larger than the JPG?

That's expected. JPG throws away information to get small; PNG keeps everything. A 2MB photo JPG commonly becomes an 8–15MB PNG. Use the resize option if the result is unwieldy.

Does my JPG become transparent?

No. PNG supports transparency, but a JPG has none to carry over, so the converted image is fully opaque. You'd remove the background in an editor afterwards.

Are my images uploaded anywhere?

No. Conversion runs inside your browser tab using the HTML Canvas API. The image data never leaves your device, and nothing is stored once you close the tab.

Is there a file size or count limit?

You can queue up to 40 images at a time, each up to 50MB. The real ceiling is your device's memory — very large photos are best done in smaller batches on a phone.

Does it work on a phone?

Yes. The interface is responsive and touch-friendly, and converted files save straight to your device's downloads.

Do you add a watermark or resize my image?

Never. Output is exactly what you asked for — the original dimensions unless you deliberately choose a resize option.

JPG to PNG — Overview

About this tool

What is JPG to PNG?

JPG to PNG converts JPG and JPEG photos into lossless PNG files in your browser. PNG stores every pixel exactly as given, which makes it the required format for a surprising number of tools: design software, some printers, certain upload forms, and most image-editing pipelines where you'll be re-saving repeatedly.

The important thing to understand is what conversion can and cannot do. PNG will preserve the JPG perfectly from this point forward — no further generation loss no matter how many times you edit and re-save. It cannot recover detail the original JPG compression already discarded, and it cannot add transparency that was never there.

The practical result is a bigger file that is safe to edit. That is usually exactly the point.

How to use

How to use JPG to PNG

1
Drop your JPG files
Add one image or a whole folder. Both .jpg and .jpeg extensions are accepted.
2
Optionally resize
PNG files are large. If you don't need full resolution, capping the width here keeps the result manageable.
3
Download your PNGs
Grab each file, or take the batch as a zip.

Use cases & scenarios

Where it fits

Editing without generation loss

Every time you re-save a JPG it degrades slightly. Convert to PNG first and edit as many times as you like with no cumulative damage.

Meeting a PNG-only requirement

Some design tools, app-store asset specs and upload forms accept PNG exclusively.

Preparing a base for a transparent cutout

PNG supports transparency, so convert first and then remove the background in your editor.

Which format should I use?

JPG for photographs and anything you e-mail. PNG when you need transparency or perfectly sharp screenshots and diagrams. WebP when you control a website and want the smallest files. AVIF for the very smallest files, when you know your audience uses recent browsers.

Final thoughts

The bottom line

Converting JPG to PNG is about protecting an image from further damage, not repairing past damage. Do it before you start editing, and every save after that is free of consequence.
