How to convert JPG to PNG
Upload one or more JPG files and download the PNG versions. The whole process runs locally in your browser — your files are never sent to a server.
PNG uses lossless compression, which makes it a solid choice for graphics, screenshots, and images you plan to keep editing without losing quality. For photos where small file size matters most, JPG or WebP usually work better.
Frequently asked questions
Why convert JPG to PNG?
PNG is a lossless format, so it's a good choice when you want to edit an image repeatedly without accumulating compression artifacts, or when you need a format that supports transparency for later editing.
Will converting to PNG improve quality?
No — a JPG has already been compressed, so converting to PNG preserves exactly what's there but can't restore detail that was lost. PNG just prevents any further quality loss from that point on.
Are my images uploaded anywhere?
No. Conversion happens entirely in your browser using the HTML canvas, so your images never leave your device.
Can I convert multiple JPGs at once?
Yes. Add several JPG files and each is converted to PNG separately for download.
