Convert JPG to WEBP
Turn JPG images into WEBP files right in your browser. No upload, no signup, no watermark.
Convert a JPG photo to WebP for a real, measured size saving — typically 25–35% at matched visual quality — with the encode verified in your browser before you download anything.

About JPG to WEBP
Why WebP is usually smaller
WebP uses more modern prediction than JPG's block-based transform, so it represents smooth gradients and soft detail — skies, skin, out-of-focus backgrounds — more efficiently. On an already heavily compressed JPG the gain shrinks, and occasionally the WebP comes out larger; the result panel reports the real numbers either way.
A verified encode, not a guess
Before converting, the tool runs an actual test encode to confirm your browser can genuinely produce WebP output. If it can't, you get a clear message instead of a file that's silently still a JPG wearing a .webp extension.
Settings and output
Quality slider
80 is the sweet spot for most web photography. Push to 90+ for images shown large or full-bleed; values below 60 start to show smoothing and colour banding in gradients.
When to use it
- Cutting page weight on a site that currently serves JPG photos.
- Preparing lighter images for an app, email template or CDN.
- Testing the real byte saving on a specific photo before committing to a format switch site-wide.
Limitations to know
- The conversion is lossy — it does not restore detail already lost by the JPG encoder.
- A handful of older desktop editors and print workflows still don't accept WebP files.
- Metadata such as EXIF camera data and GPS tags is not carried into the output.
Common problems and fixes
The WEBP is bigger than my JPG, not smaller.
This happens when the source JPG is already compressed hard — there's little left for WebP to gain, and re-encoding it can slightly increase size. Keep the JPG in that case rather than forcing the conversion.
It says my browser can't produce WEBP.
A small number of older or locked-down browser builds lack a WebP encoder. Try a current version of Chrome, Firefox, Edge or Safari.
Will people on old phones be able to see the WebP?
Every browser released in the last several years supports WebP. If you specifically need compatibility with very old software or a print vendor, keep a JPG copy as well.
How to use it
- 1Drop a JPG onto the upload area. The tool first runs a real encode test to confirm your browser can write WEBP — no user-agent guessing.
- 2Choose a quality value. 80 is the sweet spot for web photos; 90+ for hero images you'll display large.
- 3Convert. The output is verified to be a genuine WEBP blob, so a browser that silently falls back to another format is reported as an error instead of handing you a renamed file.
- 4Read the saving percentage — it's calculated from actual bytes — and download.
Frequently asked questions
How much smaller is WEBP than JPG?
At matched visual quality, typically 25–35% for ordinary photographs. Images with smooth gradients save the most. A heavily compressed JPG may convert to a larger WEBP, in which case keeping the JPG is the right call.
Can everyone open a WEBP file?
Every current browser displays WEBP, and most modern apps accept it. Some older desktop editors and print workflows still don't — keep a JPG copy if the file is going to a client or a printer.
Is WEBP lossy like JPG?
In this tool, yes: it uses lossy WEBP with your chosen quality. That means the same rule applies — convert once from your best source rather than re-encoding an export of an export.
Does converting keep my EXIF data?
No. Canvas-based conversion produces clean image data with no metadata attached, which is usually what you want for publishing.
What happens if my browser can't encode WEBP?
The tool runs a real test encode before converting and tells you plainly if WEBP output isn't available, rather than silently renaming a JPG or handing you a broken file.
Should I use 80 or 90 quality for a hero image?
90+ if the image is large and will be viewed close up or full-bleed; 80 is plenty for images below roughly 800px wide, where compression artefacts are much harder to see.
Can I convert a JPG that's already heavily compressed?
You can, but WEBP re-compresses compression artefacts that are already there, so the saving is smaller and sometimes the WEBP ends up larger than the JPG — the result panel reports that honestly.
