Cleanor: Image Compressor, Converter & Screenshots

Compress & convert images (HEIC, AVIF, WebP, PDF), take screenshots, and save every image on a page. On your device, private.

Cleanor is a fast, private image toolkit that lives in your browser toolbar. Compress and convert your pictures, resize and crop them, capture screenshots, and save every image on a page, all without uploading a single file. There is no account, no server, and no tracking: your images are processed on your own device and never leave your computer. Whether you are speeding up a website, shrinking a photo to fit an email limit, turning iPhone HEIC pictures into JPG, or grabbing a full page screenshot, Cleanor gets it done in a couple of clicks. WHAT YOU CAN DO Compress images Reduce image file size by up to 90% with a simple quality slider, or set an exact target like "under 200 KB" and let Cleanor find the best quality for you automatically. Every result shows exactly how much you saved, so you can compress images with confidence. Convert between formats Convert images to WebP, AVIF, JPEG, PNG, or PDF. Open HEIC (iPhone) and AVIF photos and save them as universal WebP, JPEG, or PNG that opens anywhere. It doubles as a reliable HEIC to JPG converter and a WebP converter that runs completely offline. Resize and crop Resize by maximum width, fit within set dimensions, an exact width by height, or a percentage, with one tap presets (4K, 1920, 1280, 800). Crop to a fixed aspect ratio such as 1:1, 4:3, 3:2, 16:9, or 9:16 for avatars, thumbnails, and social posts. Batch process Add many images at once by drag and drop, the file picker, or paste from the clipboard, then download them all as a single ZIP archive, or combine them into one multi page PDF. Right click any image Right click a picture on any web page and choose "Convert image with Cleanor", then pick WebP, AVIF, JPEG, PNG, or PDF. The converted file downloads instantly with no extra window. You can also copy any result straight to your clipboard to paste it into a document, email, or chat. Save every image on a page Right click a page and choose "Download all images" to grab them as one tidy ZIP, or "Convert all images" to compress an entire page into a single archive. Files are named correctly by type, even when the site's image links have no file extension. Built in screenshots Capture the visible area, the full scrolling page (Cleanor scrolls and stitches it for you, like a dedicated full page screenshot tool), or a region you draw with your mouse. Screenshots download instantly, named by site and time, with no screen recording and no debugger permissions. WHY CHOOSE CLEANOR 100% on device Your images are processed by your browser plus small bundled offline codecs. Nothing is uploaded, which makes Cleanor ideal for private, confidential, or client work. EXIF, GPS, and camera metadata are stripped automatically on every conversion. Private by default Cleanor asks for no access to your websites when you install it. Optional, revocable access is requested only when you use a right click or page action, and you can always just drag and drop instead. Fast and free No sign in, no ads, no tracking. It works offline and remembers your preferred format, quality, resize, and crop settings between sessions. There is even a keyboard shortcut to open the optimizer instantly.

Nothing is ever sent to a server. Is Cleanor free? Yes. There is no sign in, no subscription, and no ads. Does it work offline? Yes. Once installed, compression, conversion, resizing, cropping, and screenshots all work without an internet connection. Can it convert iPhone HEIC photos? Yes. Open HEIC or HEIF files and save them as JPG, PNG, or WebP that opens on any device. What formats can it export? WebP, AVIF, JPEG, PNG, and PDF. You can also combine several images into one multi page PDF. Will converting reduce quality? You stay in control. Use the quality slider, choose an exact target file size, or pick PNG for lossless output. Does it remove metadata? Yes. EXIF, GPS, and camera metadata are stripped automatically when an image is re encoded, which is better for your privacy. Why does it ask for site access sometimes? Only when you use a right click or page action that needs to read the image bytes, and only for that action. You can decline and simply drag and drop your files instead.
