While ConceptShare has a long list of supported file formats and optimization guidelines, it does not mean that all formats are equally efficient. The result of improper optimization of your file has a downstream impact on everyone who needs to look at and review the asset.
It is important to make a distinction between file formats that ConceptShare supports and those that are optimized for web browsers. For example, ConceptShare supports many different image formats, as well as document file formats, but web browsers may not be optimized to display most of these file types. Therefore, when you upload file formats that browsers do not support, ConceptShare first converts these files into a proxy format, such as JPEG for images and PDF for documents, which the browser can display to reviewers.
- ConceptShare supports PSD so you can upload the 1000-MB file as is.
- Export the PSD file to a flat image format like TIFF, which would shrink the file size down to 100 MB, and then upload the file to ConceptShare (better option).
- Export the PSD file as a web-optimized image format (for example, JPEG, PNG), which would likely shrink the file size down to less than 100 MB, and then upload the file to ConceptShare (best option).
- As the asset uploader, you will spend less time uploading each asset (1000 MB file vs. 20 MB file).
- As a reviewer, you will spend less time waiting for a large asset to be downloaded and displayed.
- JPEG / PNG for images
- PDF for documents
- Video using h.264 at 1080p or 720p, and Audio using AAC codecs
