How to image compressor

  1. 1

    Choose your Images files

    Click the upload area or drag files onto it. Nothing is uploaded — files are opened locally.

  2. 2

    Adjust the settings

    Pick quality, output format, and maximum width or height, then press the convert button.

  3. 3

    Download the result

    Save each file individually or everything at once as a ZIP.

Shrink photos and screenshots for email attachments, upload forms with size limits and faster web pages. Pick a quality level and an optional maximum size; if an image can’t be made smaller, you get the original back untouched.

What is Images?

PNG, JPG and WebP images are supported as input.

Is it private?

Yes. Unlike upload-based converters, ZapMorph processes files inside your browser tab, so the file stays on your device. It is never transmitted, stored or logged — close the tab and it’s gone.

Frequently asked questions

Is the image compressor converter free?

Yes. Convert 1 file a day without an account, or 5 files a day with a free account. Pro removes all daily limits.

Are my files uploaded to a server?

No. The conversion runs entirely in your browser, so your files never leave your device. We only count how many files you convert — never their names or contents.

What is the maximum file size?

Up to 25 MB per file without an account, 50 MB with a free account, and 1 GB on Pro. Very large files also depend on your device’s memory.

Can I convert multiple Images files at once?

Yes. Select several Images files at once — up to 5 on the free plan or 50 on Pro — and download all results in a single ZIP.

Does it work on Mac, Windows, iPhone and Android?

Yes. It works in any modern browser — Chrome, Edge, Firefox and Safari — on desktop and mobile, with nothing to install.
