OPTIMIZE WEBP
WebP is the workhorse format of the modern web: meaningfully smaller than JPG and PNG, supported by every current browser, and accepted by far more platforms than its newer rivals. Most images you save from websites today come down as WebP, and most sites that care about speed serve it.
These tools cover both directions of that reality. Convert your PNG and JPG images to WebP to make pages lighter, or convert WebP downloads back into JPG and PNG when an app, editor or upload form refuses them. Everything runs natively in your browser, with nothing uploaded.
| Format | File size | Transparency | Best for |
|---|---|---|---|
| WebP | Small | Yes | Everyday website images with broad platform support |
| AVIF | Smallest | Yes | Cutting-edge sites squeezing out every kilobyte |
| JPG | Medium | No | Universal sharing: every app and device opens it |
| PNG | Largest | Yes | Lossless editing, screenshots and sharp graphics |
WebP arrived with a simple pitch: JPG-like photos and PNG-like graphics at a fraction of the weight, with transparency included. A photo converted at quality 85 typically lands 25 to 35 percent smaller than the JPG original with no visible difference, and PNG graphics often shrink far more than that.
A decade of browser support means it now works everywhere that matters, and unlike newer formats it is also accepted by most CMS platforms, marketplaces and tools. That combination of savings and reach is why WebP remains the default recommendation for site images.
The format has one recurring annoyance: an image saved from a website arrives as WebP, and then an older editor, a printing service or an upload form rejects it. The fix takes seconds. WebP to JPG produces the most compatible file possible, and WebP to PNG produces a lossless copy that keeps transparency for editing work.
One detail worth knowing: some WebP files are animated. Converting those to a still format keeps the first frame, so for animations you want to stay in WebP or use the GIF tools instead.
If your pages still serve PNG screenshots and JPG photos, converting them is one of the highest-value performance wins available. Run graphics through PNG to WebP and photos through JPG to WebP at quality 85, and most pages shed a third or more of their image weight without anyone noticing a difference.
Keep the originals as your masters, and serve WebP on the site. If you want to go further, AVIF is smaller still, and the picture element lets you serve AVIF first with a WebP fallback so every visitor gets the best format their browser handles.
Almost always yes. Photos typically shrink 25 to 35 percent versus JPG and graphics often far more versus PNG, with no visible quality change at sensible settings. Every current browser supports it.
Open the WebP to JPG converter, drop in your files and download the JPG copies. The conversion runs natively in your browser with nothing uploaded, and JPG output opens in essentially every app ever made.
Yes. PNG output is lossless and preserves the full alpha channel, which makes it the right choice for logos, graphics and anything headed into an editor.
AVIF files are 20 to 30 percent smaller again, but WebP is accepted by more platforms and tools. The strongest setup is AVIF with a WebP fallback via the picture element; if you maintain one format, WebP is the safer default.
The encoder here is lossy, but at quality 85 the result is visually identical to the original for normal images. Keep your originals as masters and treat the WebP copies as the versions you publish.
Converting an animated WebP to JPG or PNG keeps the first frame only, since those are still formats. For animations, keep the WebP or work with the GIF tools instead.
Browser support arrived years before desktop software caught up, so older editors, viewers and upload pipelines still reject the format. Converting once to JPG or PNG fixes it permanently.
No. Your browser decodes and re-encodes everything on your own device, so files never touch a server and there are no size caps or daily limits.
