How to convert JPG to WebP

Transform your JPG images into WebP in seconds. Everything runs in your browser — no file ever leaves your device.

4 min readUpdated on April 25, 2026

You want transparency, higher visual quality, or to work in an editing pipeline that needs exact pixel preservation. You're publishing to the web — direct bandwidth savings with no visible quality loss.

What is JPG?

A lossy-compressed image format created by the Joint Photographic Experts Group in 1992. It's the most universal photo format — every browser, app, and OS opens JPG without anything extra.

  • Photos with lots of detail and color variation
  • Images sent over email or social media
  • Cases where file size matters more than absolute quality
  • Mid-quality print material

Why convert to WebP

A modern format created by Google in 2010, designed for the web. Supports both lossy and lossless compression, transparency, and animation. WebP files are ~25-35% smaller than equivalent JPG/PNG with similar visual quality — that's why it became the de-facto standard on optimized sites.

  • Images published on websites and blogs
  • E-commerce and online marketing banners
  • Replacing both JPG and PNG in web workflows
  • Ads and paid media (loads faster)

Step-by-step: convert your image

1. Upload the file

Drag your JPG file into the upload area, or click to select it from your computer. You can upload several files at once — they'll be converted in batch.

2. Check the quality setting

WebP has adjustable quality in most cases. Leave it at 85-90% for the best size/quality balance. For professional material, bump it to 95-100%.

3. Click convert and download

Processing is near-instant (seconds per image) because it happens right in your browser. When it's done, download each file individually or all together as a ZIP.

JPG vs WebP: technical comparison

Before converting, it's worth understanding what each format brings to the table:

JPG — best for:

  • Photos with lots of detail and color variation
  • Images sent over email or social media
  • Cases where file size matters more than absolute quality
  • Mid-quality print material

JPG — limitations:

  • No transparency (background is always opaque)
  • Repeated compression degrades quality (visible artifacts)
  • Not ideal for graphics with text, fine lines, or flat color areas

WebP — best for:

  • Images published on websites and blogs
  • E-commerce and online marketing banners
  • Replacing both JPG and PNG in web workflows
  • Ads and paid media (loads faster)

WebP — limitations:

  • Near-universal support today, but some old readers can't open it
  • Editors outside the web ecosystem (older Photoshop) may need a plugin
  • For professional print, traditional formats still dominate

  • E-commerce and online marketing banners

Frequently asked questions

Quality depends on both formats. For conversions between modern formats with similar quality (PNG → WebP, for example), the visual loss is imperceptible. For conversions to lossy formats (anything → JPG), quality depends on the level you pick — 85-90% is practically indistinguishable from the original.
