    All files are read, compressed and bundled into the ZIP inside your browser. Nothing is uploaded, so a whole batch of private images stays on your computer.

    Shrink Many Images Together

    When a folder of photos is too heavy for a website, an email or a portfolio, compressing them one by one is tedious. This batch image compressor applies the same quality setting, or the same per file size target, to everything you add, then hands back the smaller versions in a single ZIP. JPG gives the deepest savings for photos, while WebP shrinks well and keeps any transparency.

    It suits web developers trimming page weight, sellers preparing many product images, and anyone clearing space by shrinking a camera roll before backing it up.

    Compress a Batch in Three Steps

    1. Add your images. Drag in or select all the files you want to make smaller.
    2. Set the level. Choose a quality, or a target size in KB for each image, and a format.
    3. Download the ZIP. Every file is compressed and the batch downloads together as one archive.

    Quality or Target Size

    Pick a single quality level for the whole set, or set a per image KB target and let each file be reduced to fit under it, which is handy for upload limits applied to every image.

    One ZIP, Less Clutter

    The compressed results are zipped in the browser and saved together, so you avoid a flood of separate downloads and keep everything in one neat archive.

    Stays On Your Device

    The whole batch is compressed locally, so your originals are never uploaded and there is no waiting on a server queue, no matter how many files you add.

    Why Choose This Batch Compressor

    • Many at once: compress a whole folder with one setting.
    • Per image target: reduce each file to fit a KB limit.
    • ZIP download: all results delivered in a single archive.
    • No upload: the entire batch is processed in your browser.
    • Clean files: no watermark and no account needed.

    Common Uses for Bulk Compression

    Reach for a batch compressor when you need to compress multiple images at once rather than open each one by hand. It is a fast way to batch reduce photo sizes for a faster website, shrink many product or listing photos for an online store, or compress a folder of images so they fit under an email attachment limit. Add every file, set one quality level or a per image KB target, and the whole set is reduced with the same setting.

    The same approach handles a whole gallery or portfolio that has grown too heavy, letting you slim down a large set of pictures in a single pass. Because the work happens in your browser and the results are bundled together, you download all the compressed images in one ZIP instead of saving each file on its own.

    Frequently Asked Questions

    Add all your files, choose a quality level or a per image KB target and a format, then click Compress All and Download ZIP. The smaller files come back as one ZIP.

    Yes. Switch Compress by to Target size each and enter a KB value. Every image is reduced to fit under that size individually.

    No. Each file is read and compressed by your browser, then zipped locally. Nothing is sent to a server, so private batches stay on your machine.

    They are bundled into a single ZIP archive that downloads to your device, instead of saving each image separately.

    JPG usually produces the smallest files for photos, while WebP compresses well and keeps transparency. You can also keep each file in its original format.

    There is no fixed cap. Since the work happens locally, the limit is your device memory, so larger batches just take a little longer.

    Compression trades some quality for smaller files. Higher quality settings are barely noticeable, while lower settings and small targets reduce quality more.

    Yes. The batch compressor is free, needs no sign-up, and never adds a watermark.

    Drag in or select every file, pick one quality level or a per image KB target and an output format, then click Compress All and Download ZIP. The same setting is applied to the whole set in one pass.

    Add all the photos from the folder, choose JPG or WebP and a quality around 70 to 80 percent, then download the ZIP. The lighter files load faster on your pages without uploading anything.

    You do not save them one at a time. Once the batch finishes, every compressed image is bundled into a single ZIP archive that downloads to your device automatically.

    It trades a little quality for smaller files. A high quality setting is barely noticeable, while a low setting or a small per image target shrinks files more and shows more loss. The same level is applied to every image.
