What is WebP and when to use it instead of JPG or PNG
WebP appears more and more among image downloads from the internet, and many people wonder whether to use it or stay with JPG and PNG. The short answer is that WebP usually produces lighter files, but there are situations where another format is still the better choice. Let us see when.
What WebP is
WebP is an image format developed by Google and released in 2010. It brings together the best of JPG and PNG in one format: it supports lossy compression for photographs, lossless compression for graphics, transparency with partial levels and even animation. In other words, it can replace JPG, PNG and GIF.
All major current browsers, on computers and phones, display it without problems.
How much it really saves
Depending on content and settings, a WebP image with comparable visual quality usually weighs 25% to 35% less than its JPG equivalent, and for graphics with transparency it can be much lighter than a PNG. On a page with many images, that difference reduces load time, improving the experience on mobile connections with limited speed.
The improvement is not magic: it depends on the type of image. With very simple or very small images the difference can be minimal.
When to use WebP
Use it for images on websites, online shops, blogs and apps, where every kilobyte counts and the visitor uses modern browsers. It is also a good option for logos and graphics with a transparent background that you want lighter than a PNG.
It is especially recommended when you publish many product photos, since it speeds up the catalogue without the customer noticing any loss of quality.
When to stay with JPG or PNG
If you will send the image to a procedure portal, a printer or someone who will open it with old software, JPG remains the safest option. The same goes for PNG when you need maximum compatibility with transparency in office or editing software.
Many forms only accept JPG, PNG or PDF and reject WebP. If that happens, convert your file to the requested format.
How to convert to WebP with Zipnify
Choose the matching conversion tool: JPG to WebP, PNG to WebP, and also from GIF, BMP or AVIF. Select the quality, start with 80 to 85 and compare. Download the result, check the weight and make sure the important details are still sharp.
Conversion is done inside your browser, without uploading files.
A practical recommendation
For a website, always keep the originals in high quality and publish the WebP versions. If you need maximum compatibility, you can offer both. And for personal use, such as sharing photos by messaging, the format rarely matters: prioritise that the recipient can open them.
Remember that converting an already compressed JPG to WebP does not recover lost detail; the best result comes from starting with the original image.
