Image compressor / batch tool

Compress a batchof images.

Set one size limit, let each image run locally, then save the finished files one by one or together.

One setup / many files

Set the rules once.

Files stay on this device

01 / Add images

Up to 10 files · 50 MiB each · 100 MiB total

02 / Choose shared settings

Same as input keeps each original format; JPEG removes transparency. Processing stays local and runs one image at a time.

03 / Review and compress

Your batch 0 / 10

Your selected images will appear here, ready to review.

    Add up to 10 supported images to start.

    How batch compression works

    One decision. A tidy queue.

    Useful when a form, listing, or email needs several smaller images. Set a shared maximum once, review every result, and choose how to download.

    01

    Add the images

    Select up to 10 JPG, PNG, or WebP files. Unsupported or oversized files are identified before processing.

    02

    Set a shared limit

    Choose one maximum size and output format for the batch. Each file is compressed sequentially to keep browser memory use manageable.

    03

    Save what worked

    Check each file’s result, retry an error, download an image on its own, or package successful results into one ZIP.

    Private by default

    Your source files and generated results are processed in this browser, not uploaded to a server.

    One at a time

    Sequential processing avoids decoding a whole batch of large photos in parallel.

    ZIP means together

    The archive saves clicks; it does not promise additional image compression or smaller image bytes.

    FAQ

    Batch compression, answered.

    Can I compress several images at once?

    Yes. Add up to 10 JPG, PNG, or WebP images, choose one maximum size and output format, then process the batch. Each file is handled one at a time in your browser.

    Are my images uploaded?

    No. Your selected files and results stay in your browser. The tool does not send them to our server.

    Can I download the results together?

    Yes. After at least one image succeeds, create a ZIP containing the successful results. Individual downloads remain available, and failed images are not silently included.

    Does a ZIP make the images smaller?

    No. The images are already compressed; the ZIP is for collecting several results into one download, not for reducing their image file sizes further.

    What are the batch limits?

    You can select up to 10 images, with a 50 MiB maximum per file and 100 MiB combined input size. Supported formats are JPG, PNG, and WebP.

    What happens if one image fails?

    The rest of the batch continues. The failed file stays visible with an explanation and a retry action; successful files can still be downloaded individually or as a ZIP.
