Besides the exif-data, Pic8 doesn't alter images. @picman can confirm. Some of the image hosts might do (compress them to save/optimize space) and maybe even add data in them (that would only be related to pic8, since images are being uploaded by pic8 server). That's the reason I suggested you to compress them before uploading them online. You can even use a VM with a clean OS that has no internet connection to compress images or remove exif-data yourself. > Is the code available for pic8 api for people to verify? Take a random phone pic online shared by some random people that contains exif data (especially long/lat data) and upload it with pic8. Then download it from the resulting short link and compare it with the original.
