PNG ignores this — it is always lossless.

About this tool

Switch an image between JPG, PNG, and WebP without downloading desktop software. Each format has a sweet spot: JPEG handles photographs efficiently and is universally supported (every email client, every system). PNG preserves every pixel exactly and is the only one of these three that supports transparency — use it for logos, icons, and anything with a transparent background. WebP is Google's newer format that compresses much smaller than JPEG at the same visual quality (often 25-35% smaller files) and now works in every major browser. The converter runs entirely in your browser — no upload, no signup. Drop a file, pick the target format, download the result.

Frequently asked questions

When should I use PNG?
For graphics with transparency (logos, icons, screenshots with transparent areas), or when you need lossless quality (medical imaging, archival). PNG files are typically larger than JPEG or WebP for photos.
When should I use WebP?
For any image headed to the web. WebP files are 25-35% smaller than JPEG at the same visual quality. Supported in every modern browser since 2020. WebP also supports transparency, so it can replace PNG in many cases.
When should I use JPEG?
For maximum compatibility — every email client, every photo viewer, every printer accepts JPEG. Also when the recipient may be using older software that does not understand WebP.
Can I convert from HEIC (iPhone format)?
Right now, only formats your browser can decode. Most browsers decode JPEG, PNG, GIF, and WebP. HEIC support is patchy outside Safari — a dedicated HEIC converter is on the roadmap.
Why does my JPEG get bigger when converted to PNG?
JPEG is lossy compression — it discards visual information to shrink the file. PNG preserves every pixel including the JPEG artifacts. Converting JPEG → PNG never shrinks; it preserves the JPEG-compressed version losslessly. To get smaller files, go the other direction (PNG → JPEG or WebP).
