Why compress images online?
Large image files slow down websites, fill up storage, and take longer to email or share. Our free image compressor reduces file size for JPG, PNG, WebP, and BMP without uploading to our servers. Everything runs in your browser, so your photos stay private. You can compress one image or many at once and download the results or a single ZIP file.
You control the target file size (e.g. 0.5 MB or 1 MB), maximum dimension (e.g. 1920px for HD), and quality. This is ideal for preparing photos for the web, email, or social media. After compressing, you might use our resize image or crop image tools to adjust dimensions, or remove background for product shots and portraits. For passport-style photos, try our official photo maker.
Who should use this tool?
Perfect for website owners and developers who need to optimize images for fast loading, bloggers and content creators preparing images for posts, small businesses sending product photos by email or uploading to forms with size limits, and anyone who wants to free up storage or reduce bandwidth without losing acceptable quality. Because compression runs in your browser, it’s also suitable when you need to keep files private and don’t want to upload them to a third-party server.
How it works
Add one or more images; you can drag and drop or select files. Set your preferred maximum file size and quality. Click to compress; progress is shown per image. Download individually or as a ZIP. No account is required and there are no watermarks.
Frequently asked questions
Will compression reduce quality? You choose the target file size and quality. For most uses (web, email, social), a reasonable target (e.g. 100–300 KB for a large image) keeps visuals looking good. Resize to the dimensions you need first, then compress—see our compress without losing quality guide.
What formats can I compress? We support JPG, PNG, WebP, and BMP. For photos, JPG or WebP usually give the best size savings; PNG is better when you need transparency.
Are my images uploaded to your servers? No. All compression runs in your browser. Your files never leave your device.
Can I compress multiple images at once? Yes. Add multiple files, set your options, and download each result or a single ZIP.
