Compress, resize and convert images privately in your browser. 100% local processing. Your images never leave your device. Compressly is a private image compressor, resizer, converter, and export-pack generator for Chrome. Add images from your computer, optimize them locally, and download smaller files without creating an account or uploading anything to a server. Everything runs on your device. Compressly uses browser-native image decoding, Canvas, OffscreenCanvas, Web Workers, IndexedDB, and local extension storage. Your selected images are not sent to Compressly, a cloud service, analytics provider, or any third party. What Compressly can do: - Smart compression with a safe default that avoids larger output files. - Quality Guard to preserve visual similarity while reducing file size. - Target-size compression with quick presets: 20 KB, 50 KB, 100 KB, 200 KB, 500 KB, and 1 MB. - JPG, PNG, WebP, and Auto smallest-file output options. - Resize by max size, exact pixels, percentage, cm, mm, or inches with DPI conversion. - Form-photo presets for passport photos, signature uploads, and 50 KB form uploads. - Web, social, ecommerce, email, WordPress, and archive profiles. - Batch processing with controlled worker concurrency. - Before/after comparison and per-image benchmark tools. - Download one image or export a whole batch as a ZIP. - Export Studio for responsive web packs and marketplace image packs. - Rename patterns, web-friendly filenames, and metadata stripping. - Light, dark, and system themes. Compressly is built for: - Website owners who need optimized web images. - Bloggers and WordPress publishers. - Ecommerce sellers preparing product photos. - Students and applicants who need form-ready photos or signature uploads. - Designers and marketers preparing social and Open Graph images. - Anyone who wants image optimization without uploading private files. Important limitations: - Animated GIFs are optimized as a single still frame. Animation is not preserved. - PNG output does not support quality-based target-size search. Use WebP or JPG when large size reduction is the goal. - Compressly does not include AI background removal, HEIC conversion, OCR, cloud sync, or remote processing.
