See the official platform ceiling separately from provisional guidance about when splitting may improve real-world upload reliability. The PDF body stays in your browser.
The file body is not uploaded to Split2AI for this check.
50 MB or less is shown as “smaller / safer-side”, 50–150 MB as “consider splitting”, and above 150 MB as “splitting strongly recommended”. These are not official platform thresholds and do not guarantee upload success. PDF structure, image density, embedded fonts, page count, network conditions and service-side processing can all matter.
The default split target is 50 MB. Official hard limits are checked separately.
