Supported image formats, color profiles, and tips
When you upload an image into Micrio, it gets processed by our tiling servers. This means that the original image, even if it's a 5GB TIFF file, will be broken up to individual tiles on multiple zoom levels, optimizing it for good streaming delivery in the user's browser. Meaning, the user will only download the parts of the image that they are looking at, and zooming into.
So for Micrio, it really doesn't matter how large the original size of your upload is-- the processed image results in a large number of individual tiles, by default in WebP format.
Image formats
The default supported image formats by Micrio are:
- JPEG
- PNG
- WebP
- TIFF
There are no hard resolution limits inside Micrio's system-- however, some file formats are limited themselves. For instance, JPEG supports images up to 4 gigapixels (65,535 x 65,535px), and PNG is limited to (about) 2.5 gigapixels.
TIP
For (very) large images, we recommend using our Image Uploader App for locally processing the images to greatly speed up the processing and upload of your images.
Vector images
Only rasterised images are supported for zoomable images. Micrio doesn’t support SVGs because drawing these is a very heavy operation for the browser which results in a suboptimal experience for the user. To use your vector image, export is as a high resolution raster image first.
Color profiles
Since Micrio is a web-based platform for use in the browser, it does not support advanced or custom image color profiles. When you are uploading images in Micrio, please make sure that they are in Standard RGB (sRGB, or IEC 61966-2-1:1999) color format.
Failing to do so may result in a wrong, more dull colouring after the image processing.
Since custom or commercial color profiles allow for many degrees of freedom and color fine tuning, if you are unsure, please get in touch with the original image creator(s) and ask them for an sRGB version of the images you want to upload.
Image layers
If you are uploading an image that contains multiple layers (TIFF, PSB for instance), they will be flattened to a single raster layer by our tiling servers.
This can possibly result in some artifacting when you are using transparency in your layers.
We recommend preparing your image by flattening it to a single raster layer. Not only does this prevent artifacting, it also greatly reduces the image file size, and Micrio processing time.
Micrio output image formats
In most cases, images uploaded in Micrio will result in WebP encoded image tiles. This is generally the most optimal for a balanced image size and quality, with support for image transparency. To tile to JPG, or PNG tiles, you can do that using our Uploader CLI tool.
