WebP is generally the better choice for web use today: it produces smaller file sizes at comparable visual quality and supports alpha transparency, which JPG lacks entirely. JPG remains the safer choice when you need maximum compatibility — with older software, printing services, and tools that don't yet support WebP.
WebP vs JPG at a glance
| Factor | WebP | JPG |
|---|---|---|
| Typical file size | Often 25–35% smaller than JPG at comparable visual quality, per Google's own published WebP comparisons | Larger on average for the same visual quality |
| Transparency | Yes — full alpha channel support | No alpha channel |
| Animation | Yes — supports animation | No |
| Browser support | All modern browsers, universally since roughly 2020 | Universal — supported by software dating back to the 1990s |
| Editing software support | Native support in current versions of Photoshop, GIMP, and similar tools, but many older versions and print/embroidery/legacy tools still don't recognize it | Universally supported everywhere |
| Best for | Web pages, app UI, anywhere Core Web Vitals or page speed matters | Email, Office documents, print workflows, older or niche software |
Which should you use?
The right answer depends on where the image is going, not on which format is "better" in the abstract.
- Publishing to the web, and you control the display context: use WebP. Smaller files mean faster page loads, which matters for both user experience and search ranking signals.
- Sending the image somewhere you don't control — email, a client, a print shop, or an older piece of software: use JPG. It's the format least likely to get rejected or rendered as a broken icon.
- You need transparency in a lossy-compressed file: WebP is your only option between these two, since JPG has no alpha channel at all.
This comparison covers WebP vs JPG specifically. For an even smaller file size in modern browsers, AVIF is worth considering too — see our AVIF to JPG converter for the reverse direction, or use the format selector on our homepage tool to convert into AVIF.

Frequently asked questions
Is WebP always better than JPG?
Usually, but not always. WebP is typically smaller at comparable visual quality and supports transparency, which gives it the edge for most web use. JPG still wins on universal compatibility with older software, print workflows, and legacy tools that have never been updated to recognize WebP.
Can I convert between WebP and JPG for free?
Yes. PhotoConvert offers a free JPG to WebP converter and a free WebP to JPG converter, both of which run entirely in your browser with no signup, no watermark, and no upload to a server.
Does WebP lose quality compared to JPG?
At comparable quality settings, no meaningful visible difference exists for most photos. WebP's lossy compression algorithm is at least as efficient as JPEG's, which is why it can usually match JPG's visual quality at a smaller file size.
