When to use JPEG vs PNG
The most widely used format for photographs. Lossy compression produces much smaller files with minimal visible quality loss at 75-85 quality. A lossless raster format with full transparency support. Ideal for logos, icons, screenshots, and UI elements with sharp edges.

|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | No | Yes |
| Best for | Photographs, complex images | Logos, icons, screenshots |

Websites and landing pages
Converting images to PNG reduces file size and improves page load speed, which directly affects Google Core Web Vitals.
Email and document attachments
PNG files are typically smaller and more compatible across email clients and document workflows than JPEG.
Social media and content
PNG format ensures your images display correctly across social platforms without unexpected re-encoding artifacts.
Design and development workflows
PNG is widely supported in design tools and browsers. Export assets in the right format for handoff without extra steps.
Your files never leave your browser.
Most online tools upload your file to a server, convert it remotely, then send it back. This converter is architecturally different. Conversion runs via the browser's Canvas API on your own CPU. There is no server that receives your JPEG file. Not even temporarily.
