What this JPG to PNG converter does
This free JPG to PNG converter changes JPEG images into PNG files directly in your browser. It is useful when a form, design workflow, app, or editing process specifically needs PNG instead of JPG.
The output keeps the same pixel dimensions as the source image. PNG uses lossless encoding, so the converted file avoids adding another layer of JPEG compression on future saves or edits.
How JPG to PNG conversion works
Read the JPG
The tool loads the JPG or JPEG image in your browser and prepares the existing pixels for export.
Draw to canvas
The image is rendered to a canvas at the original width and height so the PNG keeps the same dimensions.
Export as PNG
The canvas is encoded as a PNG file, then shown in the preview and offered as a direct download.
Worked example
Suppose you have a 1600 × 900 JPG screenshot that you want to annotate in a design tool that prefers PNG files.
Input
- Format: JPG
- Dimensions: 1600 × 900 px
- Use case: Screenshot or reference image
- Goal: Save as PNG for editing or repeated export
Output
- Format: PNG
- Dimensions: 1600 × 900 px
- Compression: Lossless container
- Best for: Editing, archiving, annotation, and repeated saves
The image will not magically become sharper, but future edits can stay in PNG format without introducing new JPG compression each time.
When to use PNG instead of JPG
Choose PNG when
- You want a lossless output file for future editing.
- You are exporting screenshots, diagrams, or annotated images.
- Your workflow or upload form requires PNG specifically.
Keep JPG when
- You need smaller files for web delivery.
- You are dealing with photos where lightweight size matters most.
- You do not need a lossless working format.

Frequently asked questions
Does converting JPG to PNG improve image quality?
It does not restore detail already lost in the JPG. The new PNG avoids additional lossy compression, but any compression artifacts present in the original JPG will remain visible.
Why convert JPG to PNG at all?
PNG can be useful when you want a lossless output format for editing, annotation, screenshots, repeated saves, or workflows that specifically require PNG files.
Is this JPG to PNG converter private?
Yes. The conversion happens locally in your browser, so your image is not uploaded to a remote server by this tool.
