JPG
JPEGThirty years on, still the default for photographs. Its lossy compression discards detail the eye barely notices, and quality 75–85 is the sweet spot where files shrink dramatically without visible damage. No transparency support.

PNG
Portable Network GraphicsLossless compression with a real alpha channel, created as a free replacement for GIF. Perfect for logos, screenshots and interface art with sharp edges; wasteful for photographs, where JPEG or WebP will be a fraction of the size.

Questions about converting JPG to PNG
Is this JPG to PNG converter free?
Yes. Converting JPG to PNG here is free, with no account, no watermark and no daily quota. The work runs on your own device, so there is no server cost to pass on to you.
Is my JPG file uploaded anywhere?
For browser-based pairs, your file is read locally and converted by Squoosh in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
Is there a file-size limit for JPG to PNG?
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
Does converting JPG to PNG lose quality?
Nothing is intentionally discarded in this step, because PNG is lossless. A JPG file encoded with lossy settings stays lossy, so missing detail is not recovered.
Can I convert several JPG files to PNG at once?
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
Does JPG to PNG work on a phone, Mac or Chromebook?
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
