Frequently asked questions
Can I compress multiple images at once?
Yes. Select up to 30 supported image files, set a target KB and maximum dimension, and process them locally in the browser.
Does bulk compression guarantee the exact KB?
The tool aims below the target using JPEG quality and dimension reduction. Image content varies, so inspect the result and use the exact compressor for strict portal submissions.
Are bulk images uploaded?
No. The files are processed with browser Canvas APIs and are not sent to this site for conversion.
When to use a bulk image compressor
Bulk processing is useful for a folder of general images, listings, documents, or social assets. Exam and government portals can require a specific crop, format, and verified KB range; use a dedicated exam workflow when those constraints matter.
