How to Convert Images to WebP / PhotoScape X and Online Tools

Converting JPG or PNG images to WebP can reduce file size while preserving good visual quality. For a blog, this can make image-heavy pages load faster without forcing you to remove useful screenshots or photos.

This guide explains how to convert images to WebP with PhotoScape X or a browser-based converter, how to choose a practical quality setting, and what to check before publishing the converted files.

Convert images with PhotoScape X

PhotoScape X is an all-in-one image editor with tools for photo editing, batch editing, viewing, collages, animated GIFs, screen capture, and more. Its batch editor is useful when you need to convert several blog images to WebP at once.

Install PhotoScape X

Install PhotoScape X before you begin. Windows users can follow this guide to find and install PhotoScape X from the Microsoft Store. The app is available in free and paid Pro editions and supports common editing tasks as well as RAW images.

Convert images to WebP in PhotoScape X

1. Open PhotoScape X.
2. Select Batch from the top menu.
3. Choose the folder containing your images from the folder tree in the upper-left corner.
4. Select one or more images and drag them into the center workspace.
5. Click Save in the lower-right corner.

6. Select WEBP as the image format.
7. Choose an appropriate quality setting.
8. Click OK. PhotoScape X saves the converted images in the selected folder with the specified names.

Choose a WebP quality setting

The right quality setting balances clarity and file size. A very low setting may introduce visible blur or compression artifacts, while a very high setting may deliver little reduction in file size.

For images embedded in a blog post, a quality value between 70 and 85 is usually a practical starting point. Use 80 or higher for travel or food photography where fine detail matters. A value around 70 may be sufficient for simple screenshots and explanatory graphics.

Always inspect the result after conversion. Compare the original and WebP versions, paying particular attention to small text, edges, gradients, and color shifts.

• The WebP image below was converted at 90% quality and is 104 KB.

• The WebP image below was converted at 80% quality and is 64 KB.

What to check when converting blog images

First, keep the original files. If you delete the source JPG or PNG after conversion, you may not have a sufficiently large or clean file for a later redesign. Keeping separate source and converted-image folders makes future edits easier.

Second, confirm that transparency survives the conversion. This is especially important for logos, icons, and banners that rely on a transparent background.

Third, check whether your publishing platform accepts WebP uploads. Most modern websites and blogging platforms support WebP, but some older systems may restrict uploads or fail to generate previews.

Use an online WebP converter

If you do not want to install an application, you can convert images in a web browser. For example, the following tool performs the conversion locally in the browser and lets you adjust image quality:

Because the conversion takes place without uploading the image files to a server, it can also be useful when you prefer to keep the source files on your device.
