Free Image Compressor
Reduce image file size up to 80% without losing quality
About this tool
The Image Compressor shrinks your file size while keeping the picture good enough for websites, email, forms and social uploads. Big photos and screenshots slow pages down, bump into upload limits and make sharing a hassle. Compression keeps the same dimensions but trims the weight.
It's a good fit for bloggers, shop owners, students, marketers, developers — really anyone getting images ready for the web. Drop in a JPG, PNG or WebP, pick a quality level, and download the smaller version once it's done.
This matters a lot for SEO and page speed. Lighter images load faster, use less data and feel smoother on mobile. For most photos, a middle-of-the-road quality setting cuts the size way down and you'd be hard-pressed to spot the difference.
When to Compress Images
Compress before you upload — to a website, a product page, a blog post, a CMS, an email campaign, a job application, or any form with tight file limits. It also helps when you're sending photos over a slow connection or trying to keep a portfolio light.
For website images especially, do it up front rather than waiting until the page already feels sluggish. Keeping your assets small from the start saves you from cleaning up the mess later.
Choosing the Right Quality
Somewhere around 70-85 works well for most web photos. Push it higher for product shots, portfolios or anything detailed where quality really counts. Drop it lower for thumbnails, previews, or images where a small file matters more than perfect sharpness.
PNGs behave differently from JPGs — they're built for sharp graphics, transparency and screenshots. If a PNG stays stubbornly large after compression, try converting it to WebP or JPG when you don't actually need transparency.
