Capabilities
Built for private, web-ready images
Two capabilities cover the job: free JPEG, PNG, and WebP compression in the browser, and client-side processing that never uploads your files.
02
Private Client-Side Optimization
Compression runs entirely in your browser. No data is uploaded to any server. Nothing is queued, stored, or shared, so brand assets and client work stay on your machine.
- Client-side
- No upload
- Device-only

Deep dive
Everything you need to know about Braiv Image Optimizer
Most online image compressors upload your files to a server before they shrink them. That is slow, and it is the wrong default for brand assets, client work, or anything you would rather keep on-device.
Braiv Image Optimizer compresses JPEG, PNG, and WebP entirely in your browser so you can produce web-ready files without an account, a queue, or a privacy tradeoff.
Smaller images, faster pages, better rankings
Image weight is one of the easiest Core Web Vitals wins available. Oversized hero images and thumbnails delay Largest Contentful Paint, which costs you rankings and conversions on exactly the pages you spent the most time building. Compress before you upload and the same visual quality arrives in a fraction of the bytes.
Pick the format that fits the job
WebP is usually the right default for websites because it holds detail at much smaller sizes. JPEG remains the safest choice for photography and older email clients, and PNG is the one to keep when you need clean transparency for logos and UI graphics. Export to any of the three from the same upload, and compare quality against the original before you download.
Part of a free toolkit that keeps going
Optimizing images is one job in a bigger publishing workflow. Pair this tool with Braiv Compressor when the next file is video, or move up to the Braiv platform when you want thumbnails, captions, and metadata generated from the video itself.
