About JPG → WebP

Why convert JPG to WebP?

WebP gives you the same perceived photo quality as JPG with significantly smaller files, which means faster page loads and lower bandwidth bills. Every modern browser (Chrome, Firefox, Safari, Edge) renders WebP natively. If your site still serves JPG to non-Retina viewports, switching to WebP is the easiest win for Core Web Vitals.

What's the right quality setting?

WebP quality 80–85 usually matches JPG quality 90 visually, while being ~30% smaller. For hero images keep 85+. For thumbnails and decorative photos, 70–75 still looks clean and saves more bytes. The quality slider in verto previews the trade-off in real time.

Are my JPGs uploaded anywhere?

No. verto is a static page. The JPG bytes are decoded with the browser's Canvas API, re-encoded as WebP, and offered back to you as a download. Nothing leaves the tab. Closing the tab erases every file.

Each link below opens the converter with the right output pre-selected.

Supported formats

JPG, PNG, WebP and AVIF cover almost every web and design workflow. GIF input is accepted but only the first frame is used. Conversions run entirely in your browser.

TIFF, SVG, HEIC, RAW, PSD, AI, EPS and PDF are not supported in this version. Please export to JPG or PNG first if your source is in one of those formats.

Frequently asked questions

Is this image converter free?

Yes. verto is free to use, no account is required, and there are no paid plans.

Are my images uploaded to a server?

No. verto runs entirely in your browser. Your images are never uploaded, never seen by our infrastructure, and never stored anywhere outside your device. When you close the tab, every file is gone.

Which formats are supported?

Inputs: JPG, PNG, WebP, AVIF and GIF (first frame). Outputs: JPG, PNG, WebP and AVIF. TIFF, SVG, HEIC, RAW, PSD, AI, EPS and PDF are not supported in this version.

Can I convert images to WebP?

Yes. WebP is one of the recommended output formats and is supported in the browser on all modern devices.

Can I convert images to AVIF?

Yes, if your browser supports AVIF encoding. Most up-to-date Firefox and Chromium-based browsers do; if your browser refuses, you'll see a clear error and you can pick another format.

Why is HEIC not supported?

HEIC needs a separate, licensed codec that is not yet practical to run in the browser. Until that changes, please export HEIC images to JPG or PNG first.

Does JPG support transparency?

No. JPG cannot store transparent pixels. When you convert a transparent image to JPG, verto fills the transparent areas with white and shows a warning on the file row.

Can I convert multiple images at once?

Yes. You can convert up to 50 images in a single batch and download them individually or as a single ZIP.

Is there a file size limit?

Yes. Each file may be up to 20 MB. There's no daily or hourly cap because nothing runs on a server — your device is doing the work.

Are ads required to use the tool?

No. Ads are isolated from the converter. The tool works completely even if ads fail to load or are blocked.
