Good to know
Converting to JPG or lossy WebP applies the quality level you choose. JPG and BMP have no transparency, and our GIF encoder does not carry transparency either — transparent areas are flattened to the background for all three. Animated GIF input is read as its first frame.

How to convert JPG to WebP

  1. Click Choose files (or drag & drop) and select one or more JPG files. You can also paste an image from your clipboard.
  2. Adjust the quality slider if you want smaller files or maximum fidelity (92% is a good default).
  3. Press Convert to WebP. Each file is converted with a live progress indicator.
  4. Open the download page to save your files individually or grab everything as a single ZIP.

Why convert JPG to WebP?

WebP encodes the same photo roughly a quarter to a third smaller than JPG at equal visual quality. If you publish images online — a blog, a shop, a portfolio — converting JPGs to WebP is one of the easiest page-speed wins available. Set the quality slider to taste and batch-convert entire folders.

What this tool preserves — and what it changes

✓ Preserved

  • Dimensions — no resizing happens on this path
  • Visual appearance at the quality you pick (default 92%, adjustable 50–100%)

↺ Changed

  • A second lossy generation: the JPG's existing compression is baked in and the WebP encode adds its own — converting back and forth never recovers detail
  • EXIF metadata (camera, GPS) is stripped by the canvas re-encode

Known limits & edge cases

  • The size win depends on the source: an already heavily-compressed JPG re-encodes smaller but softer — the Labs quality ladder charts size against quality with this same encoder
  • A browser without a WebP encoder gets an explicit error suggesting a current Chrome, Edge or Firefox — not a wrong-format download

About the formats

What is a JPG file?

JPG is the most widely used photo format on the web. It uses lossy compression that keeps file sizes small while preserving the detail that matters in photographs. Nearly every device, browser, app and website accepts JPG, which makes it the safest choice for sharing and uploading pictures. It does not support transparency or animation.

What is a WebP file?

WebP is a modern image format developed by Google that compresses roughly 25–35% smaller than JPG at the same visual quality, and also supports transparency and animation. It is the default download format on many websites today. All current browsers display WebP, but some older apps, photo editors and printing services still reject it — which is the most common reason to convert it.

A one-step page-speed upgrade

If your site still serves JPG photos, converting them to WebP is one of the cheapest performance wins available: typically 25–35% smaller files at the same visual quality, which compounds across every image on the page and every visitor on a slow connection. Faster image loading improves Largest Contentful Paint, one of the Core Web Vitals that Google uses in ranking — so the benefit is measurable, not cosmetic.

Use the quality slider deliberately. Re-encoding an already-compressed JPG at a very high WebP setting can occasionally grow the file; around 80–85 is the sweet spot where WebP’s encoder does its best work on photographic content. Batch-convert an entire image folder in one drop, download the ZIP, and swap the files in your CMS — file names are preserved with the new extension, so references are easy to update.

Frequently asked questions

Is this JPG to WebP converter free?

Yes — completely free, with no sign-up, no watermarks and no daily quota. Processing happens in this browser, so the practical limit is the memory available on your device.

Can I convert multiple JPG files at once?

Yes. Select or drop as many files as you like — each one is converted in sequence with its own progress status, and you can download the results individually or all together as a ZIP archive.

Will I lose quality converting JPG to WebP?

WebP uses lossy compression, so there is a quality/size trade-off you control with the quality slider. At the default 92% the difference is practically invisible while files stay small. For archival-grade copies choose PNG instead.
