Processed entirely in your browser — nothing is uploadedWhy PNG photos are often oversized
PNG is designed for lossless storage, which is great for screenshots and graphics but wasteful for photographs, where JPEG's lossy compression can cut the file size dramatically with barely any visible change. If a form is rejecting your PNG photo for being too large, converting to JPEG here — and compressing further with our size compressor if needed — usually solves it in one step.
How to use Convert PNG to JPEG
- Upload the file you want to convert using the upload box above.
- The tool reads the file and converts it automatically — no extra settings to fill in for most conversions.
- Preview the converted result shown on screen.
- Download the converted file, ready to use anywhere the original format wasn't accepted.
Tips for best results
- Keep your original file until you've confirmed the converted version opens correctly wherever you need it.
- If a converted file looks wrong, double-check your browser actually supports decoding the source format (this matters most for newer formats like HEIC and AVIF).
- Batch conversions go faster if your source photos are a similar size — very large files take longer to process.
❓ Frequently asked questions
Is there a watermark on the converted file?
No — the output is a clean file with no watermark or branding added.
Does this work offline?
The page itself needs to load once from the internet, but the conversion itself happens locally in your browser without needing an ongoing connection.
Will my transparent PNG background survive conversion to JPEG?
No — JPEG doesn't support transparency, so any transparent areas will become solid white.
How much smaller will my file get?
It varies by image, but photographic PNGs often shrink by 60-90% when converted to JPEG at good quality.
Should I compress further after converting?
If your form has a specific KB limit, run the JPEG through our flexible compressor afterwards to hit that exact target.
