Does converting a JPG to PNG improve image quality?

No. JPG compression is lossy, meaning pixel data was discarded when the file was originally saved. Converting to PNG preserves whatever quality remains, but does not recover lost data. The image will look identical before and after the conversion.

Will the converted PNG have a transparent background?

No. JPG files do not support transparency, so the converted PNG will have a solid background matching the original. To remove a background, you would need to do that separately in an image editing tool after converting.

Why is the PNG file larger than the original JPG?

PNG uses lossless compression, which stores all pixel data without discarding anything. JPG achieves smaller file sizes by permanently removing data the algorithm considers redundant. The PNG is larger because it retains the full decoded pixel information and cannot compress it as aggressively.

Is there a file size limit for the converter?

There is no server-side upload limit because files never leave your browser. Practical limits depend on your device's available memory. Very large images may be slow to process on lower-end devices.

Is the JPG to PNG converter free?

Yes. QuickBrew's JPG to PNG converter is free to use with no account required, no watermarks, and no file count limits.

How to Convert a JPG to PNG (Without Losing More Quality)

Convert JPG to PNG now

You have a JPG, but you need a PNG. Maybe the platform you're publishing to requires it, maybe you're dropping it into a layered design file, or maybe you're about to edit the image multiple times and don't want the quality to degrade further with every save. JPG isn't built for that workflow. PNG is.

When You'd Need This

The most common reason to convert a JPG to PNG is editing continuity. JPG applies lossy compression every time you save. If you're going through multiple rounds of edits (color correction, resizing, cropping) each save compounds the degradation. Converting to PNG first locks the current pixel state in place, so subsequent saves don't add more artifacts on top of existing ones.

Some platforms and tools explicitly require PNG. Certain CMS platforms, app stores, and design tools (Figma, Canva, presentation software) treat PNG as the expected format for logos, icons, and UI assets. If a tool is rejecting your JPG or the output looks wrong, the format requirement is often the issue.

Graphic designers also reach for PNG when they need transparency support. JPGs don't support transparent backgrounds. The conversion itself won't add transparency to your image (more on that below), but it puts your file in a format that can hold transparency once you edit out the background.

What's Actually Happening During the Conversion

Converting a JPG to PNG does not restore quality. That's the most important thing to understand about this process. JPG compression is lossy, meaning the original pixel data was discarded when the JPG was first created. Those pixels are gone. The conversion takes whatever pixel data remains in the JPG and wraps it in PNG's lossless format.

What you're getting is a guarantee that no further quality will be lost on future saves. The artifacts already present in the JPG will still be there, frozen in place, but they won't get worse. For images that are visually clean already, this is often a perfectly acceptable trade-off for a more stable editing format.

The file size increase is real and sometimes significant. PNG uses DEFLATE compression, which is lossless. JPG achieves its small file sizes through DCT-based lossy compression, which can throw away a lot of data. A 500KB JPG might become a 1.5–2.5MB PNG, sometimes more depending on image complexity and dimensions.

JPG vs PNG: Format Comparison

Property	JPG	PNG
Full name	JPEG (Joint Photographic Experts Group)	Portable Network Graphics
Typical file size	Small (high compression)	Larger (2–5x JPG at equivalent dimensions)
Quality model	Lossy (data discarded on save)	Lossless (no data lost on save)
Transparency	Not supported	Supported (8-bit and full alpha)
Browser support	Universal	Universal
Best use case	Photographs for web display	UI assets, logos, editable graphics, transparency

Your Files Stay in Your Browser

QuickBrew's converter runs entirely in WebAssembly in your browser tab. Your images never leave your device. Nothing is uploaded to a server, no account is required, and the files aren't logged or stored anywhere. That makes it suitable for client work, product photography, and anything else where you'd rather not send files through a third-party service.
