Compress dozens of images at once — all processing happens in your browser, and you get one ZIP file back.
This free bulk image compressor lets you select or drag-and-drop dozens of JPG, PNG, or WebP images at once, compress them all to your chosen quality level, and download every compressed image together in a single ZIP file — much faster than compressing images one at a time.
Compression happens locally using your browser's Canvas API, so none of your images are ever uploaded to a server. It's ideal for photographers, bloggers, and online sellers who need to shrink many product or blog images before uploading them elsewhere.
You can select as many as your browser can comfortably handle — typically 50-100 images at once works well on most devices.
70% is a good balance between file size and visual quality for most photos. Lower it for smaller files (product thumbnails, web use), or raise it for higher quality (print, detailed images).
No — every image is compressed locally in your browser using the Canvas API. Nothing ever leaves your device.
You can upload JPG, PNG, or WebP images. All compressed output is saved as JPG for maximum compatibility and smaller file size.
