Why Use This Tool

PNG supports transparency and lossless compression, making it the preferred format for logos, screenshots, web graphics, and any image that will be edited further. JPG doesn't support transparency and degrades every time you re-save it. Converting to PNG locks in the current quality and prevents further loss.

Most online converters upload your files to their servers for processing. This tool runs entirely in your browser using the Canvas API — your images never leave your device. You can batch convert up to 5 images at once, and each conversion preserves the original image quality pixel-for-pixel.

Note: converting JPG to PNG will not recover quality already lost during JPG compression, and PNG files will typically be larger. But for any workflow where you need PNG format, this is the fastest private way to get there.

Frequently Asked Questions

No — converting from JPG to PNG does not recover quality lost during JPG compression. JPG is a lossy format, and the quality reduction is permanent. However, converting to PNG prevents any further quality loss since PNG is lossless. The image will look exactly the same, but won't degrade if edited and saved again.
PNG supports transparency (alpha channel), which JPG does not. PNG also uses lossless compression, so editing and re-saving a PNG file won't degrade quality further. Designers, web developers, and anyone needing transparent backgrounds often need PNG instead of JPG.
No — all conversion happens entirely in your browser using the Canvas API. Your images never leave your device. You can verify by disconnecting from the internet after the page loads — the tool continues to work.
Usually yes — PNG uses lossless compression which produces larger files than JPG's lossy compression. A 500KB JPG might become a 2–5MB PNG. This is normal and expected. The trade-off is that PNG preserves every pixel perfectly with no compression artifacts.
You can convert up to 5 JPG images at once. Each image is processed sequentially in your browser. For larger batches, simply run the tool again after downloading your first batch.
