JPEG to PNG Converter

Convert JPG and JPEG images into PNG files locally in your browser. Keep the image’s pixel dimensions and download each PNG or the complete batch as a ZIP.

Convert JPEG to PNG in three steps

Select JPEG images or drag them into the workspace.
Choose Convert. The browser decodes each image and creates a PNG at its original pixel dimensions.
Download individual PNG files or choose the ZIP option for several images.

When PNG is a useful choice

PNG is useful when an application asks for that format or you plan to edit an image without repeatedly applying JPEG compression. This conversion keeps the decoded image dimensions; it cannot restore detail already discarded when the JPEG was created. A photograph saved as PNG can be much larger than its JPEG source.

What happens to transparency and metadata?

A JPEG has no alpha transparency. Converting it to PNG keeps its existing background; it does not cut out the subject. The browser re-encodes the decoded pixels, so camera metadata and embedded profiles are not guaranteed to survive. Color can vary with browser decoding and profiles. Keep the original for archival or color-critical work.

From images to PDF

If your real goal is a document, use JPG to PDF directly. To combine PNG images into a document, use Image to PDF JPEG to PNG JPEG to JPG Pixels to inches. Check pixels to inches before choosing a print size. Our JPEG-to-PNG guide explains the quality trade-off.

How this conversion works

The conversion uses the browser’s image decoder and PNG canvas export. See the canvas export documentation for browser behavior.

Questions and answers

Does this upload my photographs?

No. The selected images are read and converted in your browser. This tool has no image upload endpoint.

Can I convert several JPEG files at once?

Yes. Select up to 30 files per batch and download them individually or as a ZIP.

Will PNG make a blurry JPEG sharp?

No. The export cannot reconstruct lost detail or remove blur.

Will the PNG have a transparent background?

No. The JPEG background remains unless you remove it in an image editor.

Why is my PNG larger than the JPEG?

PNG and JPEG use different compression. PNG often needs more storage for photographs.

Which files are accepted?

JPEG files up to 40 MB each. PNG conversion limits decoded images to 32 megapixels to reduce browser memory failures.

Convert JPEG to PNG without expecting recovered detail

PNG can store a newly decoded image without adding JPEG-style compression, but it cannot reverse detail already lost in the JPEG source. Use it when a destination requires PNG, and compare the file size with the original. A larger PNG is not proof of a sharper picture.
