Convert an Image — Free & Private
Convert between PNG, JPEG, and WebP right in your browser. Everything runs locally — nothing is uploaded.
PNG vs. JPEG vs. WebP
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| PNG | Lossless | Yes | Logos, screenshots, text-heavy images |
| JPEG | Lossy | No | Photos, no transparency needed |
| WebP | Lossy or lossless | Yes | Smaller web files at similar quality |
When to convert
Converting a photo from PNG to JPEG usually shrinks it dramatically with little visible difference, since PNG isn't built for photographic detail. Converting to WebP is worth trying whenever file size matters most — it supports both lossy and lossless modes and generally beats both PNG and JPEG at the same visual quality. Convert to PNG when you need transparency or lossless editing, such as a logo or a screenshot with sharp text.
Frequently Asked Questions
Does this upload my image to a server?
No. The conversion happens entirely in your browser using the Canvas API. Your image is never uploaded or transmitted anywhere.
Which formats can I convert between?
You can convert PNG, JPEG, and WebP images to any of those three formats.
Why convert to WebP?
WebP typically produces smaller files than PNG or JPEG at a similar visual quality, which is why it's a common choice for faster-loading websites.
Does converting to PNG lose quality?
No, PNG is lossless. Converting a JPEG or WebP to PNG won't lose any additional quality beyond what the original file already had, though the file size may increase.
Can I convert images automatically, without a browser?
Yes — the free Image Tools API lets you convert images from a script, backend job, or AI agent, with the same logic that powers this page.
