Leave it on Best Quality, or pick a KB target (20/50/100/200KB or custom) if you need a specific file size.
Click Convert
The file downloads automatically as soon as it's ready.
JPG vs WebP
Compression. Both are lossy formats, but WebP's compression algorithm is newer and generally more efficient at the same visual quality - it typically needs fewer bytes to represent the same photographic detail than JPG does.
File size. For photos, WebP files are commonly 25-35% smaller than an equivalent-quality JPG, though the exact figure varies by image content.
Quality at matching size. At the same file size, WebP tends to show fewer visible compression artifacts (blockiness, blurring around edges) than JPG, since its compression is better suited to modern content.
Browser support. Every current major browser supports WebP natively, and it's been a recommended web image format for several years - compatibility is rarely a concern today.
Common Use Cases
- ·Shrinking an existing photo gallery or blog's images to speed up page load
- ·Preparing product photography for an ecommerce site without sacrificing visible quality
- ·Reducing page weight to improve Core Web Vitals and search performance scores
- ·Converting camera or phone photos before publishing them online
Frequently Asked Questions
Not at equivalent settings - WebP typically matches JPG's visual quality at a smaller file size, rather than trading quality for size.
Yes - set a target size in KB and the tool searches for the highest quality that still fits under it.
It depends on the image, but a 25-35% reduction at matching visual quality is a common result for photographic content - busier, more detailed photos tend to compress less dramatically than simpler ones.
You just need to reference the .webp file instead of the .jpg wherever the image is used - a plain <img> tag with a WebP source works in every modern browser without any special markup.
All current major browsers (Chrome, Firefox, Safari, Edge) support WebP. Only very old browser versions, now a small share of traffic for most sites, lack support.
No - once JPG or WebP compression has discarded detail, converting to a different format afterward can't bring it back. If you need to preserve the option of a fully lossless copy, keep the original file too.
It's good practice to keep your original as a backup, especially if you might need to re-convert at different settings later or use the image somewhere WebP isn't accepted.
