A real format conversion
The tool reads a JPEG file, decodes its pixels, and encodes a new PNG file. It checks the output header and dimensions before enabling Download. Changing a filename extension alone would not perform this conversion.

JPG to PNG
JPEG to PNG prepares a compatible copy when the next application, document, or upload form needs a different image format. Original and Result share a large preview, with both actual file sizes shown in the settings panel. The PNG encoder keeps the decoded pixels without adding a lossy compression step. This changes the storage format, not the detail the original captured.

UNDERSTAND THE RESULT
A little context before the next click.
The displayed dimensions stay
The result uses the same displayed width and height as the decoded source. There is no hidden resizing, cropping, or upscaling. Use Image Resizer separately when the destination also requires a different pixel size.
Lossless does not mean recovered detail
PNG stores the decoded image without further lossy compression. If the JPEG was already lossy, conversion cannot restore missing texture or remove compression artifacts. The PNG may be substantially larger.
HOW TO USE IT
From an original to a clear next step.
- Choose a still JPEG file, drop it into the workspace, or try Sample. The file contents are checked instead of trusting its extension.
- Switch between Original and Result to compare the PNG copy. The JPEG background stays part of the picture; PNG conversion does not automatically remove it.
- Check both file sizes and the result dimensions. Switch between Original and Result, using Fit or 100% to inspect either image.
- Download the .png copy. Your original JPEG remains unchanged. Clear releases the current image from the workspace, or choose another file to begin again.
EVERYDAY USES
Small image tasks, with room to see.
Match an upload requirement
When a service accepts PNG but not your JPEG, create a genuine compatible file. Check the service’s pixel and byte limits separately; format conversion alone does not guarantee they will be met.
Prepare for further editing
A PNG is useful when a later editing step benefits from avoiding another lossy save. Retain the source as well, particularly when its metadata, color profile, or original compressed size matters.
Understand the storage tradeoff
Look at the actual JPEG and PNG sizes instead of assuming one format is always smaller. Image content, source compression, and the browser encoder all influence the result.
YOUR IMAGE, YOUR DEVICE
Local processing. A separate result.
The selected image is read and processed in this browser. This tool does not upload the file to a server or save it in browser storage. Choosing another file or leaving the tool releases its working images. Downloaded copies remain wherever your browser saves them.
Every change starts from the original image in memory. Export creates a new raster file; original EXIF, camera information, and embedded profile metadata are not copied. Browser decoding and color management can affect the result, so keep your original for archival work.
This release handles one file at a time, up to 25 MB, 16 megapixels, and 16,384 pixels on either side. Animated images are rejected rather than flattened to one frame. Browser encoding support can vary. A failed export shows an error and never leaves an outdated result ready to download. Read the site privacy policy for the surrounding website.
File sizes and limits use decimal units: 1 KB = 1,000 bytes and 1 MB = 1,000,000 bytes. Rounded labels are for readability; target checks compare exact bytes.

Before you save or share.
Will JPEG to PNG improve quality?
No. Conversion changes the format. It cannot recover detail already lost in the original, increase real resolution, or repair blur automatically.
Does the image become transparent?
No. JPEG has no transparent pixels. Its existing background is copied into the PNG. Use a separate background-removal workflow if you need a cutout.
Why is there no quality slider?
PNG encoding is lossless for the decoded pixels, so a JPEG-style quality slider would suggest a tradeoff this tool does not make. The browser chooses the PNG encoding details.
Will the file get smaller?
Not necessarily. A compressed source can become a larger output, especially when converted to PNG. Both actual file sizes are shown before you decide to download.
Can I convert animated JPEG?
This converter accepts standard still JPEG files. It does not assemble, extract, or preserve animation sequences.
What happens to color and metadata?
The browser decodes the pixels and manages color conversion. Original EXIF, embedded profile metadata, and camera fields are not copied into the new raster. Keep the original for archival or color-critical work.
ANOTHER SMALL TASK?
Keep the next step close.
Ready for the image in front of you?
Make a PNG copy of your JPEG, with the same pixels and a clear size comparison.
