Image Compressor

Compress images fast (privacy-first)

Use this Image Compressor to reduce file size for faster websites, smaller email attachments, and quicker uploads—without sending your image to a server. Processing runs locally in your browser, so your file stays on your device. Upload an image, choose a quality level, optionally set a maximum width, and download the compressed result. This is ideal for product photos, blog images, profile pictures, and any situation where you want smaller files without a noticeable quality drop. For best results, use WebP for modern browsers (usually smaller) or JPG for broad compatibility, then fine-tune the slider to balance size vs. clarity. Compression speed depends on your device and the original image resolution.

A practical approach is to reduce image dimensions first (if the photo is very large) and then compress. Most images don’t need to be 3000–4000px wide for the web. If you need exact dimensions, resize first using Image Resize, then come back to compress for the best size-to-quality result.

Recommended settings

• Photos: 70–85% quality (adjust visually)
• Large photos: set a max width like 1600–1920px
• Modern sites: try WebP first for smaller files

If you’re compressing images for a website, aim for a balance: small enough to load fast, but still crisp on mobile screens. As a rule of thumb, keep most content images under a few hundred KB when possible, and use smaller sizes for thumbnails. For text-heavy screenshots, avoid overly aggressive compression to prevent blurred text; resizing and using PNG (or high-quality WebP) is usually a better option. Your image is processed locally in the browser and is not uploaded for compression.

If you’re optimizing multiple images (for example, a product gallery), keep settings consistent so your site looks uniform. Use the same max width and similar quality levels across a set. After downloading, spot-check one or two images at 100% zoom to ensure faces, text, and edges look clean. If you notice artifacts, increase quality slightly or choose a different output format.
