How to batch compress images online

  1. 1

    Upload multiple images

    Choose several images from your device or drag them into the batch compressor. Common formats like JPG, PNG, and WebP are supported.

  2. 2

    Choose one set of compression settings

    Pick the quality and output format you want to apply across the batch. This works well when you need a consistent result for website assets, listings, or large photo sets.

  3. 3

    Compress and download the results

    Start the batch compression and download the finished images individually or as a ZIP once the run completes.

Understanding the settings

Batch compression is most useful when all images need roughly the same treatment. If some files need lighter compression and others need stronger changes, individual editing is still the better route. For consistent web delivery, using one reasonable quality level across the whole set can save time while still producing predictable results.

Compatibility, privacy, and limitations

Browser and device support

These tools are designed for modern browsers. Actual speed and maximum practical file size depend on device memory, processor speed, and how much media your browser can safely keep in memory during processing.

Format safety

If you are unsure which output to choose, start with broadly compatible formats such as JPG, PNG, WebP. They are usually the safest fallback for everyday sharing and playback.

Privacy explanation

This tool keeps image work on your device using browser-native processing where possible, which is useful for screenshots, photos, and design assets that you do not want to upload to an external server.

Things to keep in mind

  • Very large files can take longer to inspect and process because browsers have less memory headroom than native desktop editors.
  • FFmpeg-based browser processing is flexible, but long or high-resolution media can still be slower than a native desktop workflow.
  • Batch and multi-file jobs depend on total file size as well as per-file size, so large runs may need to be split into smaller batches.
