MAZANOKE is a simple image optimizer that runs in your browser, works offline, and keeps your images private without ever leaving your device.
Created for everyday people and designed to be easily shared with family and friends, it serves as an alternative to questionable “free” online tools.

Highlights from v1.1.0 (view full release note)
I’m delighted to present some much-requested features in this release, including support for HEIC file conversion!
- Added support to convert
HEIC,AVIF→JPG,PNG,WebP. - Paste image/files from clipboard to start optimization.
- When setting a file size limit, you can switch between units MB and KB.
- Remember last-used settings, stored locally in the browser.
The support from the community has been incredibly encouraging, and with over 4500 docker pulls, the project is now humbly making its way toward a 500 stars milestone.
The project also received its first donation, which I’m incredibly grateful for!
This is my to-go solution before sending photos to someone. Excellent service!
But I miss adding options in Docker, for an example default quality. I often clear cookies and other data so it’s kinda tedious to select the same options over and over again :)
I’m glad to hear it’s being used frequently! I’ve heard a similar, but not exactly the same use case, so I recommend submitting a feature request on GitHub. That way, I can review it later to assess if the feature could be included when I plan ahead for new releases.
Interesting. Is it fair to say you’ve created a web interface to standard image manipulation tools ?
If I understand it correctly, then yes, that’s the case! I’ve utitlized several libraries such as “Browser Image Compression”, “heic-to”, and more, to wrap it in a web interface.
No, this is all happening in the browser, there are no other image manipulation tools being called.
Feature suggestion: add the option to remove metadata from an image.
EXIF data is removed by default, at the moment, there’s no way to keep those data. I personally see that more as a feature than a bug though. The primary reason why there is no option to keep EXIF data is to maintain feature parity across different image formats.
I just tested the new release. Consider defaulting PNGs to convert to JPEGs unless they have a PNG-specific feature like transparency. Lots of screenshots are initially PNGs, but not because they need any PNG-specific features. Consider: In a test screenshot, it compressed 3.4% with the default 80% setting and PNG->PNG, but for PNG->JPG, it compressed 84.6%.
The conversion option “Default” is meant to retain the file format when possible, but you can actively select the other options like jpg or webp if that fits your use case better.
Nice work. I was looking for something like this to self-host for my partner. Thank you for sharing!
This is excellent, grabbing this asap ✌️
Star added and added to my collection. Really a good one, thx.
Elegantly done!
Does this support SVG, i.e. SVGOMG/SVGO? If not, that’s a glaring omission.
Currently, only SVG to PNG is supported. SVGOMG is a great tool I’ve used many times as a user, but since it runs as a Node.js app, it would require server-side processing, unlike the local browser-based approach of this app.
Surely the SVGO package can be compiled into a browser bundle.
I might look into this myself…
If you get around to it, I’d love to know about it and add that as a feature.
