Free browser-based image tools for a faster website
Images are usually the heaviest part of a web page, so getting them right is one of the biggest wins available for speed and SEO. These free image tools handle the everyday jobs, compressing, converting to WebP, resizing and cropping, without installing software or uploading your files anywhere. Everything runs on your device using the browser's Canvas API, which keeps private and client images off third-party servers and makes the tools fast enough to process a whole folder at once.
Start with the Image Compressor to reduce JPG, PNG and WebP file size, with an optional target like 100KB or 200KB for forms and uploads. Use the WebP Converter to turn JPG and PNG into lightweight WebP, or convert WebP back to JPG or PNG when you need a universal format. The Image Resizer changes dimensions by pixel or percent with presets for social platforms and common resolutions, and the Image Cropper crops to exact ratios like 1:1 and 16:9 with a draggable box.
The EXIF Viewer reads the metadata inside a photo, camera model, exposure, and any GPS location, which is useful both for understanding an image and for checking what a file would reveal before you share it. Each tool links to the others, so you can chain them: crop to the right shape, resize to the display size, then compress or convert to WebP for the smallest file.
How image optimization helps SEO and Core Web Vitals
Google measures loading performance through Core Web Vitals, and the metric most affected by images is Largest Contentful Paint, which times how quickly the main image or content block appears. Serving an image larger than it displays, or in an older, heavier format, drags LCP down and can cost you rankings on image-heavy pages. Resizing to the display size, compressing sensibly and using WebP together often cut an image's weight by an order of magnitude.
The practical workflow is simple: right-size the image first so you are not shipping a 4000px photo into a 600px slot, then compress it or convert it to WebP for the smallest file that still looks good. Doing this before you publish removes the single biggest source of slow pages and pairs naturally with the on-page checks in our free SEO tools.
Private by design, and built for batches
Because these image tools never upload your files, they are safe for sensitive photos, unreleased product shots and client work. They are also built for volume: drop in up to 200 images or import an entire folder, and the tools preserve your folder structure when they hand back a ZIP. That makes preparing a full set of blog images or product photos a matter of seconds rather than opening each file in an editor.
