Frequently asked questions
Are my photos stored anywhere?
Photos are processed in your browser, not sent to a server. They're kept there for 24 hours by default so you can resume work. Expired photos are deleted when you next open the site. You can also delete them immediately in Settings.
Does it work on phones?
Yes. Choose a photo from your library. Saved files usually go to your phone's Downloads folder.
How many photos can I add at once?
Compress, Convert and Resize accept up to 20 photos at a time, up to 25MB each. Crop works with one photo at a time.
Is it really free?
Yes—all features are free, with no account needed.
How MiruKit handles your photos
Processed in your browser, not on a server
MiruKit tools do not upload your photos, videos or drawings. Compressing, converting and cropping all run inside the browser you are using now. That is also why there is no account to create.
A few features need an extra file the first time you use them: a decoder of about 15 MB for formats such as HEIC and AVIF, and models for cut-out, upscaling and finding faces in video. Each is downloaded once and kept in the browser, so it opens straight away next time. Work in progress is kept in the browser for 24 hours by default so you can continue, and you can delete it at any time in Settings.
How much you can load at once
- One photo can be up to 25 MB and 16 megapixels (8,192 px on one side).
- Compress, Convert images and Resize take up to 20 photos and 100 MB in total at a time.
- Crop photos and Cutout & erase work on one photo at a time, because every photo is framed differently.
- The Supported formats table lists what can be read and written, format by format.
Where to start
- A form says "200 KB or less"? Enter that number in Compress.
- An iPhone HEIC photo will not open, or a PNG has to become a JPG? Use Convert images.
- Use Resize to match a blog or shop width, and Crop photos for Instagram and YouTube ratios.
- Several receipts or document photos have to be sent as one file? Bind them into a PDF in Merge & PDF.
- Use ID photo for passport and resume photos, and Watermark to put the same logo on many photos.
- Use Video face blur to hide other people's faces in a clip, and Diagram maker to draw flowcharts and org charts.
The numbers are measured
The guides report numbers from running test images through MiruKit's own processing code. For example, fitting fifteen 4000×3000 photos to 1 MB each took 50.1 seconds, and all fifteen came out under the target. The same picture saved as WebP was 35.5% smaller than as JPG, and three phone photos bound into a PDF came to about 7.8 MB.
Each guide publishes the test pictures and the raw measurements with it. Results change with the device and the photo, so the conditions of each test are written down too.
Who runs it
MiruKit is run by one person. If a tool stops or a result looks wrong, write through Contact. When the same problem comes in more than once, the tool and the guides are fixed. Why it was made and how it works is on the About page, and how photos and records are handled is in the Privacy policy.
