Image Compressor
Upload your images
Compression removes data the eye barely notices to make files smaller. Lighter images mean faster pages, lower bandwidth and better search rankings, especially on mobile connections.
Pick a format and quality
Choose WEBP or JPEG and drag the quality slider to trade a little visual fidelity for a big drop in file size. The tool reports how much each image shrank so you can find the sweet spot.
Download the optimized files
All processing happens in your browser, images are never uploaded. Save the compressed results one by one or grab them together in a ZIP.

What Is an Image Compressor?
An Image Compressor reduces the file size of digital images while aiming to preserve an acceptable level of visual quality. It removes or simplifies image data that may not be noticeable during normal viewing, producing lighter files that are easier to store, transfer, and publish online.
Large image files can increase page weight and require visitors to download more data. This can slow page loading, particularly on mobile devices or limited internet connections. Image optimisation reduces the amount of data transferred and can improve the speed at which visual content appears.
How to Compress Images
Upload the images you want to optimise, then choose WebP or JPEG as the output format. Adjust the quality setting to control the balance between visual detail and file size. A lower quality level generally produces a smaller file, while a higher level preserves more detail.
The tool displays the original and compressed file sizes so you can evaluate the reduction before downloading the result. You can save each optimised image separately or download multiple processed files together in a ZIP archive. All processing takes place in the browser, and the images are not uploaded to a remote server.
Choosing Between WebP and JPEG
JPEG is widely used for photographs and other images containing detailed colour variations. It uses lossy compression, which can substantially reduce file size by removing some image information. Excessive compression, however, may create visible artefacts or reduce sharpness.
WebP supports both lossy and lossless compression and can often produce smaller files than older image formats at a comparable visual quality. It is broadly supported by modern browsers and can be a suitable choice for website images, product photographs, banners, and editorial visuals.
The appropriate format depends on where the image will be used, the required browser compatibility, and the level of detail that must be preserved. Reviewing the compressed preview and file-size reduction helps identify the most suitable balance.
Why Image Compression Matters for Websites
Images frequently account for a significant proportion of the data downloaded on a web page. Optimising them can reduce bandwidth usage, improve mobile performance, and help pages display visual content more quickly.
Faster image delivery can also support important user experience metrics. When a large image is the main visual element above the fold, reducing its download time may improve Largest Contentful Paint performance.
Image compression is particularly useful for e-commerce product images, blog visuals, portfolio pages, landing page banners, campaign assets, and websites containing large image galleries. Optimising files before uploading them helps prevent unnecessarily heavy images from becoming part of the live website.
Balancing File Size and Visual Quality
The smallest file is not always the best result. Strong compression may reduce loading time but also introduce blurring, colour changes, or visible compression artefacts. The ideal setting keeps the image clear enough for its intended purpose while removing unnecessary file weight.
Product details, portfolio photography, text embedded in images, and highly detailed graphics may require a higher quality setting. Decorative visuals, thumbnails, and images displayed at smaller dimensions may tolerate stronger compression.
The most effective approach is to compare the original and optimised versions, review the image at its intended display size, and select the lowest file size that still provides the required visual quality.
