PNG is a superb format — until you check the file size. A single full-screen PNG photo can be several megabytes, which slows down websites and clogs up email. Converting to JPG often cuts that by 80% or more with no visible difference. But it isn't always the right move. Here's how to decide.
The quick rule
Convert PNG to JPG when the image is a photograph and you want a smaller file. Keep PNG when you need crisp text, sharp lines, or transparency.
Why JPG is so much smaller
PNG is lossless — it stores every pixel exactly, which is overkill for photographs full of subtle gradients. JPG uses lossy compression tuned for photos, throwing away detail your eye won't miss. For a sunset or a portrait, the saving is huge and the quality drop is invisible.
When converting makes sense
- Photos you want to email or post that are currently multi-megabyte PNGs.
- Images for a website, where smaller files mean faster page loads.
- Screenshots of photos (not text) that you're sharing casually.
When to keep PNG
- Logos, icons and diagrams with sharp edges and flat colours.
- Screenshots full of text — JPG adds fuzzy halos around letters.
- Anything needing a transparent background (JPG can't do transparency).
Step-by-step
- Open the PNG to JPG converter and drag in your files.
- Pick a JPG quality (90% is a safe default).
- Convert and download — one image or a whole batch.
It runs in your browser, so your images stay on your device.
Tip: Converting removes transparency — transparent areas become a solid background. If you need transparency, keep the PNG.
What about quality loss?
At 90% quality the difference is invisible for photos. Going lower saves more space but can introduce artifacts, so only drop below 80% when size truly matters. If you need it even smaller afterwards, run it through the image compressor.
Frequently asked questions
Why convert PNG to JPG?
JPG files are far smaller for photos, which helps email and website speed.
Will I lose transparency?
Yes — JPG has no transparency, so transparent areas become solid. Keep PNG if you need it.
Can I convert many PNGs at once?
Yes — batch-convert a whole folder and download them together.
