Acerca de esta herramienta

JPG's compression was designed in 1992. WebP, released by Google in 2010, uses techniques borrowed from video encoding and typically produces files 25-35% smaller at visually equivalent quality - the same photograph, a third less data. On a page carrying twenty images that is a substantial difference to load time, which is why converting to WebP is one of the standard steps in making a site faster and why Core Web Vitals reports so often recommend it. Support is no longer the obstacle it once was: every current browser handles WebP, including Safari since 2020. The remaining gaps are outside the browser - some older desktop software, certain print workflows and a few upload forms still expect JPG. So the rule is straightforward: use WebP for anything displayed on the web, keep JPG for anything being handed to another system. Conversion runs in your browser with nothing uploaded.

Cómo usar esta herramienta

  1. Add your JPG filesDrop them in or browse. Several can be converted at once, which is the usual case when preparing images for a site.
  2. Set the qualityAround 80 is the sweet spot. WebP holds detail better than JPG at the same number, so you can often go lower than you would expect.
  3. ConvertEach image is re-encoded as WebP in your browser - no upload, no queue.
  4. Download and compareCheck the size difference. A 30% reduction across a page of images is a real speed improvement.

Por qué usarla

  • Typically 25-35% smaller than JPG at equivalent visual quality, which directly improves page load time.
  • Supported by every current browser, so there is no fallback to maintain for modern visitors.
  • Batch conversion, so preparing a whole gallery is one operation.
  • Runs on your device - client photos and unreleased product shots are never uploaded.
  • No account, no watermark and no conversion limit.

Usos comunes

  • Speeding up a website, where oversized images are the most common cause of poor performance scores.
  • Acting on a PageSpeed or Lighthouse recommendation to serve images in next-gen formats.
  • Reducing bandwidth costs on an image-heavy site.
  • Preparing product photography for an online shop, where load speed affects conversion.
  • Shrinking a gallery before uploading it to a CMS.

Consejos para mejores resultados

  • Convert from your highest-quality JPG. Converting an already heavily compressed file just re-encodes existing artefacts.
  • Quality 80 in WebP looks better than quality 80 in JPG, so try lower settings than you are used to before assuming you need more.
  • Resize before converting. An image displayed at 800px wide gains far more from being 1600px than from format alone.
  • Keep the JPG originals for anything that might be sent to a print shop or older software.
  • For photographs on a website, WebP is now the sensible default rather than a special case.

Errores a evitar

  • Converting images that will be emailed or printed rather than displayed on the web, where recipients may not open WebP.
  • Expecting WebP to fix an image that is simply too large in dimensions - resize first, then convert.
  • Converting a low-quality JPG and expecting the result to look better. Format change cannot restore lost detail.
  • Deleting the JPG originals, leaving nothing for the systems that still refuse WebP.
  • Using very low quality settings because "WebP is efficient" - it degrades too, just more gracefully.

Preguntas frecuentes

Add your JPG images above, set a quality level and convert. Each is re-encoded as WebP in your browser and downloads immediately.

Yes. No account, no batch limit and no watermark.

Typically 25-35% smaller than the equivalent JPG at comparable visual quality, though it varies with image content. Photographs with smooth gradients gain the most.

No - at a comparable quality setting it generally looks the same or slightly better, because the compression is substantially more modern than JPG's.

Every current browser does, including Safari since 2020. The gaps are outside the browser: some older desktop software, print workflows and upload forms still expect JPG or PNG.

For photographs and graphics displayed on the page, yes - it is the standard recommendation from PageSpeed and Lighthouse, and the size saving is genuine. Keep JPG copies for anything leaving the website.

Yes. It runs in your browser using its own encoder, so the images are never uploaded.

AVIF compresses better still, but encoding is much slower and support, while now broad, arrived later. WebP remains the pragmatic default; AVIF is worth it for very large image libraries where the extra saving justifies the effort.
