Many mosaic providers do not create true photo mosaics and instead simply tint the images. Rapid-Mosaic on the other hand offers several different mosaic types.

Choose a subject with few details: The simpler and more high-contrast the image, the better the result – small details don’t show up well in a mosaic. The image should be at least 1000×1000 pixels. The format doesn’t matter, since you can crop it in the next step.

1. High Contrast

Light and dark areas should be clearly separated. This creates a mosaic with stronger contrast and more visible detail.

2. Large Main Subject

Your subject should take up as much of the image as possible. Avoid very small people or objects in the distance.

3. Clean Background

A clean background keeps the focus on the main subject and helps create a more balanced mosaic.

4. Good Lighting

Natural daylight or even lighting helps produce clear colors and better results.

There are no limits to your creativity: Portraits, animals, and landscapes work just as well as logos, symbols, numbers, or lettering. The most important thing is a clear, high-contrast subject.

Absolutely! You can remove the main image at any time and upload a different one. Even after the mosaic has finished processing, you can simply start over and try a different subject.

The mosaic is calculated to fit your selected format exactly: the number and arrangement of the tiles are optimized for that size and aspect ratio. That’s why you choose the format before the mosaic image is created.

You choose the material only after your mosaic image has been calculated. As soon as you receive the preview by email, you can select your preferred material during the ordering process – for example poster, canvas, acrylic, or Dibond.

Yes. Simply start a new mosaic calculation with the desired format and request a new preview. An existing mosaic can’t simply be resized, since it is always calculated for a specific format.

You should have at least 50—the more, the better. There is no upper limit, so you can also use well over 1,000 photos.

No. The photos are automatically compressed before upload, and the algorithm crops them to the appropriate format on its own when creating the mosaic.

We try to use every photo. Depending on the characteristics of the photos or the selected mosaic type (e.g. Classic, Parquet), this is not always completely possible. You can see which photos were used afterward in the preview.

Depending on the format, about 1–3 cm. After the calculation, you can choose between different tile sizes and compare them directly.

Data privacy is important to us: If no order is placed, your photos will be automatically deleted again after a certain period.

Depending on server load and the number of photos, creating your mosaic takes about 15 minutes to 2 hours. We’ll then send you the preview by email. If you don’t receive anything, please also check your spam folder.

Yes. Creating and sending the mosaic preview is free and without obligation. You only incur costs if you actually place an order.

Only to send you the preview and the link for selecting and ordering. If no order is placed, your data and photos will be automatically deleted again after a certain period.

Using the link in the email, you can choose between different mosaic versions and tile sizes and order your preferred design directly.

No. Foto-Mosaik-Edda is no longer being developed and has been merged into Rapid-Mosaic. Rapid-Mosaic 8 comes with a new mosaic engine (faster, finer mosaic images) and a new interface that lets you create your mosaic image in two steps. Rapid-Mosaic is available for Windows, macOS and Linux. fmedda.com no longer exists either; the site redirects here.

Installed versions 7.x for Windows offer the update to Rapid-Mosaic 8 at startup. Your Professional license is taken over automatically.

Would you like to stay with the old version? Foto-Mosaik-Edda 7.8.23025.1 for Windows is still available on the download page under “Older version”. It is no longer updated. You will find the Professional version 7.8 via the link in your purchase email.

With the free version of Rapid-Mosaic, you order your mosaic image directly as a poster, canvas & co. To save it as a JPG file, you have two options, both directly in the software under “Save in full resolution”:

• Single result: You unlock exactly this mosaic image and can save it as often as you like.
• Professional: You save all your mosaic images without restrictions.

Mosaic images created online can be bought as a high-resolution JPG file in the shop.

Rapid-Mosaic is not yet notarized by Apple, so macOS blocks it the first time you start it. Go to System Settings › Privacy & Security and, in the “Security” section, click “Open Anyway”. You only need to do this once. Step-by-step guide with pictures

After purchasing the software, you will receive an email with an attached license file license.lic. There is only one program: the license file turns the free Standard version into the Professional version.

• Install Rapid-Mosaic from the download page if you have not done so yet.
• Save the file license.lic from the email on your computer.
• Start Rapid-Mosaic, open Settings › License and click “Load license file …”.
• Select the saved file license.lic.

You can now use Rapid-Mosaic Professional. If you already have a Professional license for Rapid-Mosaic or Foto-Mosaik-Edda 7.x, Rapid-Mosaic 8 takes it over automatically at the first start. If you still use Foto-Mosaik-Edda 7.8, you will find the Professional version 7.8 via the link in the email.

Rapid-Mosaic tries to use every picture at least once. If pictures are missing, the variant shows the notice “X of Y pictures could not be used”. Expanded, it lists every picture with the reason:

• The file could not be opened, is damaged or incomplete (e.g. not fully transferred from the camera).
• The file format is not supported.
• No space in the mosaic: with the selected tile size there are fewer tiles than pictures. A smaller tile size makes room.

With “Copy list” you can pass the list on. In the chaos mosaic, some pictures partly lie underneath others and are therefore not fully visible.

In the “Print format” step you will find the formats for your country. You enter your own size under “Enter custom format”. Please note that only the formats from the price list can be ordered online.

The mosaic image is produced exactly as you see it in the Rapid-Mosaic preview. We do not make any changes afterward (black and white, blending, cropping). Please also note the print preview in Rapid-Mosaic. The way the tile size is displayed there is exactly how it will appear on the final product.

The dimensions of the mosaic image must be defined in the Rapid-Mosaic program before the calculation. Based on the selected print size, Rapid-Mosaic calculates the ideal mosaic image. This is the only way to ensure that the mosaic image resolution, tile size, and print preview are set correctly. After uploading the mosaic image from the Rapid-Mosaic software, only the selected print size will then be available in the order options.
