Understanding How to Convert JPG to PNG
What is JPG to PNG Conversion?
When you convert jpg to png, you transform a JPG file that uses lossy compression into PNG — the Portable Network Graphics format designed for lossless storage. Unlike JPG, PNG uses the DEFLATE algorithm to compress image data without discarding any pixels, so every jpg to png file you produce is a pixel-perfect copy of the source. Our jpg to png converter handles this conversion entirely in your browser in seconds, with no quality trade-off and no size limits.
How Our JPG to PNG converter Works
- Upload your JPG files. Drag and drop or click to select one or multiple JPG images. Our jpg to png online accepts any valid JPG file with no restrictions on size or count.
- Automatic lossless conversion. Each jpg to png image is drawn onto an HTML5 Canvas and exported as a PNG data stream. PNG is always lossless — there are no quality settings to configure.
- Download your PNG files. A single converted file downloads immediately as a
.png. If you uploaded multiple images, they are bundled into a ZIP archive and downloaded in one click.
What Gets Changed During Conversion
- Compression algorithm: JPG's lossy compressionis replaced by PNG's lossless DEFLATE compression — no pixel data is discarded or altered.
- File size: PNG files are typically larger than JPG because lossless compression retains full pixel data. The exact size depends on image content.
- Transparency: If the source format supports alpha (e.g. WebP, GIF), the transparent areas are preserved in the output jpg to png file. JPG sources have no alpha channel, so PNG output will have an opaque background.
- Metadata: Our jpg to png converter focuses on image data; EXIF and other embedded metadata are not carried across to keep output files clean.
Privacy, Compatibility & Tips
Our jpg to png online processes everything in your browser — your jpg to png image files never leave your device. PNG is universally supported across every browser, operating system, image editor, and design tool. For the smallest possible lossless file, consider using a PNG optimiser (such as TinyPNG or pngcrush) on the output; our jpg to png converter prioritises speed and correctness over post-processing optimisation.

Frequently Asked Questions About JPG to PNG converter
A jpg to png converter is a tool that transforms JPG images into PNG — the Portable Network Graphics format. When you convert jpg to png, the source file's compressed pixel data is decoded and re-encoded using PNG's lossless DEFLATE algorithm. The result is a pixel-perfect copy that supports transparency and works in every browser, editor, and design tool.
No — never. PNG uses lossless compression, so every jpg to png file you produce is a pixel-perfect reproduction of the source. There is no quality slider because none is needed. The only trade-off is file size: PNG files are typically larger than JPG because no pixel data is discarded.
Absolutely. Our jpg to png online processes everything locally using the HTML5 Canvas API. Your jpg to png image files are never uploaded to any server. No data ever leaves your device during the entire jpg to png conversion process, ensuring complete privacy.
PNG stores every pixel without discarding any data, while JPG uses lossy compression to reduce file size. A converted jpg to png file contains the full pixel information that JPG had thrown away, so the PNG is larger. This is the expected and correct trade-off for lossless quality.
PNG natively supports full alpha transparency. If your source JPG file has no transparency (like a standard JPG), the converted jpg to png file will have an opaque background. If the source format supports alpha (like WebP or GIF), those transparent areas are preserved exactly in the PNG output.
There is no hard limit imposed by our tool — processing is limited only by your device's available memory. Most JPG images convert instantly. Very large files (over 20 MB) may take a moment as the browser processes each frame, but all jpg to png conversion still happens locally at full quality.
Yes, 100% free. Our jpg to png converter has no file size limits, no signup requirement, no premium tier, and no usage caps. Convert jpg to png as many times as you need, completely free and with no watermark added to the output.
