I have several files from 12 MB to 21 MB as Tiffs but when converted to JPEG in Photoshop at 12 max file size they drop below 4 MB.
Hi G Eric,
Thanks for reaching out to the Adobe Stock community. Are you trying to upload your artwork on Adobe Stock website and encountering the above issue or are you facing troubles with some licensed images?
If you are facing troubles with the licensed image of Adobe Stock, please mention the file IDs so that we can check the files and can further assist you.
Since Adobe Stock won’t accept uploaded Tiff images they wouldn’t be licensed images. I must make high quality Jpegs from my Tiffs. And sometimes 12-20MB images only save as 3 MB jpegs which are too small for selling as stock.
Do not be confused between MEGABYTES and MEGAPIXELS! Your pictures need to be of 4 MEGAPIXELS or higher.
JPEG files of 3 to 4 MEGABYTES are probably good enough to be used on stock without visual impact due to the compression.
Thanks – that helps. I work in Mbytes so misread the megapixel requirement.
This could depend on a number of factors, such as the pixel size of the original image and the number of megapixels which shouldn't be below 4MP. Remember that JPEGs are lossy compression and TIFF is generally lossless - so no compression, as I'm sure you know.
So, the decrease in file size depends on a number of factors.
