JPG ↔ PNG is a free online PaperStack tool for image tools. Convert between JPG and PNG when a site, printer, or editor demands one format.
JPG ↔ PNG switches formats in the browser. Use PNG for logos and screenshots with transparency or sharp text; use JPG for photographs and smaller emails.
You can use it on a phone, tablet, or computer. There is no sign-up, and processing runs in your browser so files and text are not uploaded to PaperStack for storage.
How JPG ↔ PNG is useful
The wrong format either looks blocky or is huge. Converting locally avoids uploading brand logos to a random converter.
Typical reasons people open this tool:
- Finish a one-off job without installing desktop software
- Keep documents and copy on the device they already use
- Move faster than emailing a file to themselves or waiting on IT
- Pair it with other Image Tools on PaperStack in the same sitting

Practical tips
- JPG cannot keep true transparency — use PNG for logos.
- Photos as PNG are often unnecessarily large.
- Compress after conversion if size still matters.
Why use PaperStack for this
Many “free converters” ask you to upload a file to a server you do not control. PaperStack is built around browser-side processing: you open the page, do the work, and download or copy the result. That is the difference when the file is a payslip, a contract, a customer CSV, or a draft that is not public yet.
You also get a consistent layout across PDF, Word, image, CSV, and text tools, so the next job does not require learning a new app.
Frequently asked questions
Is JPG ↔ PNG free?
Yes. You can use it without creating an account or paying a subscription.
Are my files uploaded?
No. Processing runs locally in your browser. PaperStack does not need your file on a server to run the tool.
Does it work on mobile?
Yes. Use a modern mobile or desktop browser. Very large files are more comfortable on a laptop because they use more memory.
Can beginners use it?
Yes. Follow the steps above. If something looks wrong, keep the original file and try a milder setting (for example less compression).
