Convert PNG images to smaller JPGs on your device — transparency flattened to white, quality slider, bulk files, no upload.

or — multiple files welcome. Nothing is uploaded; conversion happens on your device.
Files are processed entirely in your browser — never uploaded, never stored. Large photos convert in about a second each; the first HEIC file loads a small decoder module.
How it works
PNG screenshots and photos are routinely 5–10× larger than they need to be. If the image has no transparency, converting to JPG shrinks it dramatically with no visible difference — ideal for email attachments, upload limits, and web pages.

- Choose quality — 85–90% is the sweet spot for screenshots and photos.
- Download the JPGs; transparent areas become white, so keep logos and icons in PNG.
PNG vs JPG
| PNG | JPG | |
|---|---|---|
| Compression | Lossless | Lossy (adjustable) |
| File size (photos) | Very large | Small |
| Transparency | Yes | No |
| Best for | Logos, UI, line art | Photos, screenshots without alpha |
Tip: Sharp text on screenshots survives JPG well at 90%+, but if you see fuzz around letters, keep those in PNG and use the PNG compressor instead.
Frequently asked questions
When should I convert PNG to JPG?
For photos and screenshots without transparency, JPG is typically 5–10× smaller than PNG with no visible difference — better for email attachments, uploads with size limits, and web pages. Keep PNG for logos, line art, and anything needing transparency.
What happens to transparent areas?
JPG has no transparency, so transparent pixels are flattened onto a white background. If you need transparency preserved, convert to WebP instead.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using its built-in image engine — files never leave your device, which also makes it faster than upload-based converters and safe for private photos.
