About MoaMoa
MoaMoa is a set of simple tools for everyday photo jobs: fitting a photo under an upload limit, changing its format, turning photos into a PDF, hiding details in a screenshot, and a few fun extras.
The tools run in your browser. Your files are processed on your device and are not uploaded. There is no account to create and no watermark on what you save.
Why MoaMoa exists
Everyday photo jobs keep coming up: a form wants a photo under 200 KB, an iPhone photo won't open on a work computer, an insurer wants every receipt in one PDF, a screenshot has to be shared without the account number on it. Most free tools for these jobs upload your files to a server, add a watermark, or ask you to sign up.
MoaMoa does these jobs in your browser instead. The photos stay on your device, the results have no watermark, and there's nothing to sign up for. The site is built and maintained by MoaMoa, who reads every message sent to the contact address below.
How the tools work
- Your files stay on your device. Every tool processes files inside your browser. The site's code has no upload path, and its security policy stops the page from sending data to other websites.
- Honest results. Sizes are shown in exact bytes. A result that misses your limit is marked as missing it, with the smallest size reached, never shown as a success.
- No watermark, no account. What you save is yours, as you made it. Saved photos leave out hidden details such as the location they were taken.
- Usable by everyone. Every action works with a keyboard, touch targets are large enough for a finger, and the tools are checked for accessibility problems with every change.
