Common questions
What can I do for free?
All three tools — resize, convert, and compress — are fully available for free. Free users can process up to 10 images per session with a 20 MB per-image limit. Activate a license for unlimited use.
Does ImageZero upload my images?
Never. All image processing happens entirely on your Mac. The only network request is license validation, which sends your license key — never your images.
What formats does ImageZero support?
Input: JPG, JPEG, PNG, HEIC, and WebP. Output: JPG and PNG (WebP output also available). You can mix input formats in a single batch.
Can I resize, convert, and compress at the same time?
Yes. Toggle on any combination of the three operations and ImageZero applies them all in one pass. You can also leave any operation off to keep the original size, format, or quality.
