Tips & tricks
- This is a pure lossless conversion with no quality slider — the PNG will always be visually identical to the source JPG, just in a different (larger) file format.
- The PNG will almost always be larger in file size than the original JPG — that's expected, not a bug, since PNG uses lossless compression while JPEG uses lossy compression.
- Only one file can be converted at a time — for multiple images, convert, download, click Clear, and repeat for each one.
- Only .jpg/.jpeg files are accepted — dropping a PNG, WebP, or other format shows an error asking for a JPG/JPEG file.

Frequently Asked Questions
Why would I convert a JPG to PNG?
PNG supports lossless compression and transparent backgrounds, making it better for logos, screenshots, and images with text or hard edges. If you're editing an image further, PNG preserves quality through multiple save cycles whereas JPEG degrades each time.
Does converting from JPG to PNG improve image quality?
No. Converting from JPEG to PNG stops further quality loss, but it cannot recover detail already lost during the original JPEG compression. If the JPEG looks fine, the PNG will look identical — just larger in file size.
Is my image uploaded to a server?
No. The conversion runs entirely in your browser using the Canvas API. Your file never leaves your device and nothing is stored or transmitted to any server.
Why is the PNG file larger than the original JPG?
JPEG uses lossy compression optimised for photos, achieving very small file sizes. PNG uses lossless compression, which preserves every pixel exactly — this results in larger files. PNG's advantage is quality retention and transparency support, not smaller size.
Can I convert multiple JPGs to PNG at once?
Currently the tool processes one image at a time. To batch convert, use each image in sequence — clear the previous result, drop the next file, and download. For large batches, a desktop tool like ImageMagick or XnConvert is more efficient.
What formats does the JPG to PNG Converter support?
The JPG to PNG Converter converts between jpg, jpeg, png. All conversions work in both directions — instantly, with no sign-up required.
Is my data safe when using the JPG to PNG Converter?
Completely safe. The JPG to PNG Converter processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
What image formats does the JPG to PNG Converter support?
The JPG to PNG Converter works with common image formats supported by your browser, including JPEG, PNG, WebP, and GIF. SVG support varies by tool. No format conversion plugin or driver is needed.
Does the JPG to PNG Converter work with large image files?
Yes. The JPG to PNG Converter processes files entirely in your browser using the Canvas API. Very large files (over 20 MB) may take a few extra seconds on older or lower-powered devices. Closing other tabs can free up memory for better performance.
