This free PNG to JPG converter is built for large PNG screenshots and exports that eat storage or fail upload limits. JPG usually produces a much smaller photo file for the same scene. Convert in your browser when you need a lighter copy for email, social posts, or forms. Important: transparency is lost, and clear areas typically become white. Keep the original PNG if you still need a clear background later.
Why convert PNG to JPG?
- Reduce large PNG file sizes for email and upload limits.
- Create lighter photo copies for social posts and messaging apps.
- Meet form requirements that accept JPG more reliably than PNG.
- Speed up sharing when perfect lossless quality is not required.
How to use this PNG to JPG converter
- Add your file. Choose a PNG screenshot, export, or photo.
- Convert. The PNG to JPG converter creates a smaller JPG in your browser.
- Download. Save the JPG and check that solid backgrounds look as expected.
What is a PNG file?
PNG is a common web and design format that uses lossless compression. It keeps sharp edges well and supports transparent backgrounds. That makes PNG strong for logos, UI assets, and graphics that sit over colored layouts.
For photos and detailed screenshots, PNG files can grow large. When you do not need transparency or pixel-perfect edits later, JPG is often the better sharing format. Convert only when a smaller, widely accepted photo file is the goal.
PNG vs JPG: what's the difference?
| Feature | PNG | JPG |
|---|---|---|
| Typical file size | Often larger for photos and detailed images | Usually much smaller for the same photo scene |
| Compression type | Lossless | Lossy |
| Transparency support | Yes (alpha channel) | No; transparent areas become a solid color, often white |
| Browser and app compatibility | Excellent on modern browsers and design tools | Near-universal for photos, uploads, and older software |
| Best use case | Logos, graphics, screenshots that need sharp edges or transparency | Photos, email attachments, and size-sensitive sharing |
Convert on iPhone, Windows, and Mac
iPhone
Open this page in your browser, add the PNG from Files or Photos, and download the JPG. Native iOS apps do not always offer a simple PNG to JPG export path. A browser tool is often faster for one-off converts.
Windows
Paint and Photos can open many PNG files, then save or export as JPG. That works well for single images. Use this converter when you want a quick web workflow without hunting through desktop menus.
Mac
Preview can open a PNG, then use File → Export and choose JPEG. That is a solid native option. The online PNG to JPG converter is handy when you are already in the browser or working on a borrowed Mac.
Is this converter safe?
Processing happens in your browser for this tool. Files are not sent to our servers just to convert. That is a better fit for screenshots that may include personal or work details.
Review the download before you share it. Remember that any transparent PNG areas will not stay transparent in JPG. Keep the original PNG if you still need a version with a clear background.
Frequently asked questions
Will converting PNG to JPG reduce the file size?
Often yes for photos and busy screenshots. JPG uses lossy compression, so the same image can become much smaller than a PNG.
What happens to transparent backgrounds?
JPG does not support transparency. Transparent pixels usually become white or another solid fill in the converted file.
Should I convert logos from PNG to JPG?
Usually no. Logos and icons often need sharp edges or transparent backgrounds. Keep PNG for those assets and convert photos instead.
Can I reverse a JPG back into a transparent PNG?
Not automatically. Once transparency is gone, converting back to PNG cannot restore the original clear background.
Is this PNG to JPG converter free?
Yes. It runs in your browser with no sign-up. Add a PNG, convert, and download the JPG.
