Introduction
PNG is ideal for graphics with transparency, but photographic PNGs are often much larger than equivalent JPEGs. PNG to JPG converts your PNG file to JPEG format in the browser, with a quality slider so you can choose how much compression to apply before downloading.
What This Tool Does
PNG to JPG loads your PNG into a Canvas element, fills the canvas with white (replacing any transparent pixels), redraws the image, and exports it as JPEG at your chosen quality level. The downloaded file uses a .jpg extension and is typically smaller than the source PNG when the image contains photographic content.
When to Use It
- Email attachments — JPEG files are smaller and more widely accepted than large PNG photos.
- Websites without transparency needs — Hero photos and blog images rarely need alpha channels.
- Legacy systems — Some upload portals accept JPG but not PNG.
- Storage reduction — Convert camera-exported PNG screenshots to JPG to save disk space.
- Social media — Many platforms display JPG efficiently; converting before upload can reduce upload time.
Step-by-Step Guide
- Upload your PNG file (max 25 MB).
- Set the JPG quality slider — 92% is a good starting point for photos.
- Note that transparent regions will become white in the output.
- Click Convert & Download.
- Check the downloaded JPG at full size before replacing your original.
Limitations
Transparency cannot be preserved in JPG format — this is a format limitation, not a tool limitation. Logos, icons, and screenshots with sharp text may show JPG compression artifacts, especially at lower quality settings. The tool processes one file at a time. Converting a PNG that is already small (e.g., a simple icon) may produce a larger JPG with worse quality.
Common Mistakes
- Converting logos with transparency — A logo on a transparent PNG will get a white background. Keep it as PNG or use Remove Background for transparency needs.
- Using low quality on text-heavy images — JPG compression blurs sharp edges. Screenshots and UI captures should stay PNG or use high quality.
- Assuming conversion is reversible — Converting PNG → JPG → PNG does not bring back transparency or original PNG compression benefits.
Tips
- Preview at 92% quality first; only lower if the file is still too large for your use case.
- For photos with transparency (e.g., a cutout portrait), consider Remove Background to get a clean PNG instead of filling with white.
- After conversion, run Compress Image if you need further size reduction without changing format.
- Keep the original PNG archived if you might need transparency later.
