About converting JPG to PNG
This is a free online JPG to PNG converter that runs entirely inside your browser, with no upload to a server and no account to create. JPG uses lossy compression tuned for photographic detail, trading a little fidelity for files that are often five to ten times smaller than an equivalent PNG. PNG is a lossless raster format with a full alpha channel, which makes it the default for screenshots, logos, icons and any artwork that needs clean transparent edges.
Most people convert JPG to PNG because something downstream refuses the original - an upload form, a printer driver, or an app that never added support for the newer format.
Because every conversion runs on your own device through WebAssembly builds of the same open-source engines desktop tools use, there is no upload queue, no file-size cap imposed by a server, and no copy of your JPG sitting in someone else's storage afterwards. That matters most for anything you would hesitate to hand to a third party - identity documents, contracts, medical scans, unreleased work, client material. It also means the converter keeps working with no network connection at all once the page has loaded.
JPG to PNG is one of many routes available here. If a direct path between two formats does not exist, the converter automatically chains several conversions together to reach the one you asked for, so you can get from almost any input to almost any output in a single step.

Frequently asked questions
- Is this JPG to PNG converter free?
- Yes, completely. There is no charge, no account, no watermark on the output and no daily conversion limit.
- Are my files uploaded to a server?
- No. The conversion runs in your browser using WebAssembly, so your JPG file never leaves your device and nothing is stored anywhere after you close the tab.
- Is there a file size limit for JPG to PNG conversion?
- There is no server-imposed limit, because there is no server involved. The practical ceiling is your own device's available memory, so very large files convert faster on a desktop than on a phone.
- Does converting JPG to PNG reduce quality?
- It depends on the target format. PNG output is produced at high quality settings, but converting into a lossy format always discards some data by design, and re-encoding an already-lossy file compounds that. Convert from the highest-quality source you have rather than from a previously converted copy.
