Welcome to Bannersnack Support

Resource upload - requirements and processes


Image 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 without any active corruptions on it, and we recommend uploading a maximum of 10 images at once.


Video upload

Alongside the static formats that you can upload into our design platform, you can also upload video content if you're looking to bring your work to the next level.

Uploading a video can be done roughly in the same way as you would upload regular images, however, the specifications of the uploaded files differ from the ones using static formats.


Technical requirements:

There is a maximum duration and size for the assets which you can upload in the form of videos, these being 5 minutes in terms of video duration and 100MB in terms of file size. The accepted file type for video uploads are the following: AVCHD, AVI, MKV, MOV, MP4, WEBM or WMV. 

Any difficulties that you might be facing while uploading a video file can be addressed with our technical support team, and an investigation will be started to offer you the best possible solution.


Upload process

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


To remember

We also recommend deleting the files 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.


Uploading audio files from your computer

You can now upload audio files straight on the editor if you are an active Plus and Team user. 

The accepted formats are: .wav, .mp3, and .ogg where the max file size is 10MB

Also, the audio file will only work if the designs are downloaded in MP4 or HTML5 format. 


To upload an audio file you can either go to Elements-My Uploads and use the Upload file(s) button or you can simply drag and drop the file on the canvas straight from your device.

For the design generator, you need to use the NEW LAYER button and go to My Uploads just like on the single editor or to enter into focus mode (double click on the size you wish to edit) where you can drag and drop the audio file from your device

    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:
