Upload Limits & What Is Changing
imgup.uk now uses tiered limits to keep uploads fast for genuine users while controlling abuse.
Current upload limits are live now: Guest uploads are capped at 16MB per file, API key tiers increase file-size limits, and hourly/daily protections apply.
What changed
We have moved from one-size-fits-all limits to API key tiers. This means guest uploads stay safe and controlled, while supporters get higher file size limits and better upload capacity.
