Send photos on WhatsApp without losing quality or time.
Sinmerma is a Mac app. Drag photos or videos onto WhatsApp from wherever they already are, and choose: Document, in original quality, or Media, compressed as usual. No menus, no hunting for the file.
Try it free: 20 sends in original quality, no card. Then US$4.99 for a lifetime license. For macOS 14 or later.
No more hunting for the file
To send the original, WhatsApp makes you go through + › Document and find the photo folder by folder, even when it's already open in the Finder. With Sinmerma, you drag it from right there.

Frequently asked questions
What is Sinmerma?
Sinmerma is a Mac app that lets you choose how photos and videos go out on WhatsApp. When you drag them onto WhatsApp for Mac, it shows two options: Document, which sends the original file uncompressed, and Media, which sends it compressed as usual.
Why does WhatsApp lower the quality of my photos?
To save data and storage, WhatsApp compresses the photos and videos you send as media: it lowers their resolution and file size. Sent as a document, the original file arrives unchanged.
Can't I send them as a document without Sinmerma?
Yes: in WhatsApp for Mac, with the + button › Document, finding the photo folder by folder in the file picker, even if it's already open in the Finder. Sinmerma saves you that trip: drag the photo from where it is, drop it on Document, done.
Does Sinmerma send messages for me?
No. It attaches the files to the chat you have open and stops there. You always press send yourself.
What do I need to use it?
A Mac with macOS 14 Sonoma or later, Apple silicon or Intel, and the WhatsApp for Mac app. It doesn't work with WhatsApp Web in the browser. It also needs an internet connection at least once a month to check the license.
What permissions does it ask for?
macOS's Accessibility permission, to click WhatsApp's buttons for you. It doesn't read your chats or upload your files anywhere.
How do I install it?
Download Sinmerma.dmg, drag Sinmerma to Applications, open it and allow Accessibility from its welcome window. The step-by-step guide, with fixes if something doesn't work, is at sinmerma.com/en/getting-started.
What happens when the free sends run out?
You get 20 free sends as Document, in original quality, with no time limit. When they run out, Media keeps working as usual and the Document zone offers to activate the license. Once you buy, paste the key from your email and Document works again.
How many Macs can I use it on?
Up to 3 Macs with one license. If you switch Macs, deactivate it on the old one from Sinmerma and activate it on the new one.
Does it work on Windows, iPhone or Android?
No. Sinmerma is Mac only.
Can I get a refund?
Yes. If Sinmerma isn't for you, write to us within 14 days of buying and we'll refund you.
