How to use this tool

- Processing starts automatically — there is nothing to configure.
- Check the result panel, which shows the original size, the final size and the output dimensions.
- Click Download to save it.
Converting to PNG makes the file lossless from this point on, but usually much larger for photographs. Useful when you need to edit without further generation loss.
The specification
| Input format | JPG |
|---|---|
| Output format | PNG |
| Quality | High — 90% where the target format is lossy |
| Transparency | Preserved |
| Metadata | EXIF is not carried across, which also strips GPS location data |
Why uploads get rejected
Meeting the size is only part of it. These are the failures that actually come up:
- The file is not really a JPG despite its extension. Renaming a file does not change its format.
- The file is corrupt or was only partially downloaded.
- The upload target does not accept PNG. Check before converting.
How it works
Your browser decodes the JPG file, then re-encodes it as PNG. Both steps use the browser's own image pipeline, so no library is downloaded and nothing is sent over the network.
Where the source has transparency and the target format does not support it, transparent areas are filled with white rather than black — the default that catches people out with other converters.
Who uses this
Fixing format rejections on upload forms, preparing images for software that only accepts certain formats, and reducing file size where the source format is inefficient.
Frequently asked questions
Does converting lose quality?
The conversion itself is high quality, but note that quality already lost in the source cannot be recovered. Converting a heavily compressed JPEG to PNG preserves the artefacts at a larger file size.
Is EXIF data preserved?
No. Metadata including camera details and GPS coordinates is discarded during conversion. For most people that is a privacy benefit, but if you need EXIF retained, this is not the right tool.
Can I convert several files at once?
Not currently — one file at a time. Each conversion takes under a second, so a small batch is quick.
Are my files uploaded to a server?
No. Everything runs inside your browser on your own device. Your file is never transmitted and never stored by us. You can confirm this by opening your browser’s Network tab while you use the tool — you will see no upload request.
Is there a limit on how many files I can process?
No. There is no daily cap, no account, and no watermark. Because the work happens on your device rather than our servers, there is nothing for us to ration.
Is this tool really free?
Yes — no account, no trial, no watermark, and no cap on usage. It runs on your own device rather than our servers, so there is no cost for us to pass on.
Does it work on mobile?
Yes. The interface adapts to phone and tablet screens, and everything runs in the browser, so there is no app to install.
