Image upload file requirements

Upload technical requirements:

The maximum accepted file size is 10 MB and the accepted file formats are JPG, PNG, SVG and GIF.

You can learn more about detailed SVG specifications here.

Our recommendations and tips:

Even if the size limit is 10 MB we strongly recommend using JPG and PNG files under 5 MB and SVG and GIF files under 3 MB.

You need to make sure your file has a correct extension and it’s not corrupted and we recommend uploading a maximum of 10 images at once.

Simply drag your images into the upload box or use the buttons provided to choose the images you want to upload.

We also recommend deleting the images you aren’t using for a better experience and a faster loading time.

When saving your design, all the contained images will go through various compression and resize processes to get the smallest possible HTML5 package.

    I've uploaded the images per requirement, the images look great in the editor but the output still became blurry. Could you tell me why?

    I agree. Mine are super blurry when exporting JPGs or PNG. And when we try and upload SVGs it will not let us, saying this:

    "The following SVG file(s) may contain embedded fonts, images or may be exported incorrectly:"

    So at the moment, the only images we can successfully use that are not blurry are the stock assets that Bannersnack provides. We can't upload our own.

    Hello guys,

    Sorry for the late reply!

    When working with digital files there is always a trade-off between file size and quality. If you're struggling to export your banners in the best possible quality but still preserve file size under a certain value, you might want to check these tips we have for you:

    1. Avoid using large images when not needed

    The biggest impact on the final HTML export is related to the images you upload so we recommend optimizing images prior to importing them in our platform. It is best to upload images that you crop to the area of interest and at the dimension of the banner at most.

    2. Use SVG files instead of classic JPG or PNG files for logos

    If possible use SVG files for all your logos, they scale to any size and are much lighter in the final banner export as well, you can find a guide with our requirements for the SVG files here.  

    3. Increase or decrease the quality of your image using the quality slider:

    If you're exporting the banner in HTML format and you're using JPGs then make sure to increase the quality to 100% for best results and if you are above limit work your way down from there.  

    However, some complex SVG files with too many points are not compatible with our platform so we recommend simplifying the path by redrawing it and that should solve the issue.

    Here's a guide about that:
