Compress multiple images at once, right in your browser. No upload, no account, no cost.
Why I like it
We've tried a lot of image compressors. This one is the fastest and most effective we've found for batch work. Drag in a handful of images, adjust your quality settings if you want to, and download them all compressed. That's it.
It handles JPEG, PNG, and WebP, and you can set max file size and dimension limits per batch. The defaults are solid for most web use, but having that control matters when you're optimizing for a specific platform or page speed target.
Why it's free (and safe)
Everything runs locally in your browser. Your images never leave your machine. There's no server on the other end receiving, processing, or storing your files, which means there's no infrastructure cost to pass along to you. It also means your images stay completely private, which is worth noting if you're working with client files or anything you wouldn't want sitting on a third-party server.
No account. No signup. No limit on how many images you run through it.
Why image compression matters
Large images are one of the most common reasons websites load slowly. A single uncompressed photo can be 3-5MB. Multiply that across a homepage with several images and you're asking visitors to download 20MB+ before the page even renders. Most people won't wait for that.
A good compressor can reduce file sizes by 50-70% with virtually no visible difference in quality. That means faster load times, better SEO performance, and a smoother experience for anyone visiting your site, especially on mobile.
When to use it
Any time you're adding images to your website, uploading product photos, or prepping assets for a project. If you're batch-processing more than a couple files at a time, this tool makes quick work of it. Get in the habit of compressing before you upload and your site will thank you for it.
