Why compress JPGs to 100kb
Large JPG image files can quickly become problematic when you're trying to upload them to a website, share them via email, or post them on social media. Many platforms impose strict file size limits, and oversized images often get rejected or take ages to upload. If you're working with product photos for an online shop, profile pictures for professional platforms, or images for a blog post, keeping your JPGs under 100KB ensures they'll load quickly and won't hit any size restrictions. Slow-loading images frustrate visitors and can even hurt your website's performance in search rankings.
Compressing your JPG files to 100KB makes them much more manageable without sacrificing too much visual quality. You'll find this particularly useful when you're uploading multiple images to a listing site, sending portfolio samples to clients, or optimising graphics for email newsletters where every kilobyte counts. Smaller files also mean faster page load times and less strain on your data allowance when you're working on mobile.
Zamzar's online JPG compressor handles this task quickly and simply. You can upload your image, let Zamzar compress it to your target size, and download the optimised file in moments. There's no need to install software or learn complicated settings, making it straightforward to get your images web-ready and shareable.
