Tool guide

How to use this tool

1. Add the required input

Enter or upload the information Image Compressor needs.

2. Run the tool

Use the main action to create, check, calculate, convert, or preview the result.

3. Review the result

Check the output before copying, downloading, or using it in important work.

When it is useful

Add up to 20 PNG, JPG/JPEG, or WebP images (25 MB maximum each). Choose an output format and quality, or set an optional best-effort target KB size for JPEG/WebP. Process the batch locally, compare the original and output file sizes, then download individual files or a ZIP. A target size is not guaranteed.

This is most helpful when you need a quick image review or draft before moving into a larger workflow.

FAQs

Are files uploaded while optimizing?

No. The image is decoded, resized when requested, encoded, previewed, compared, and downloaded in your browser.

Will the optimized file always be smaller?

No. Output size depends on the source image, format, quality, and browser encoder. Review each actual output size; some files may be larger.

Does the quality setting affect PNG?

No. Browser PNG export does not use the quality slider. Use JPEG or WebP for adjustable quality and best-effort target-size compression.
