Upload Limits & What Is Changing
To keep imgup.uk fast and sustainable, we are introducing sensible anti-abuse limits on shared upload access.
Current upload limits: 20 uploads/day/IP (website and ShareX/API) + hourly per-IP/per-account protection + guest file size limit of 25MB.
Why this is needed
Upload volume has grown significantly, and a portion of automated or low-value uploads drives storage and bandwidth costs. These limits help keep the service stable for legitimate users while we build better key tiers.
What this affects today
- Website uploads and ShareX/API uploads are limited to 20 uploads/day/IP.
- Hourly limits also apply to prevent bursts and abuse.
- Guest uploads (without API key) are limited to 25MB per file.
- Guest web uploads require successful Turnstile verification.
- ShareX/API single-file uploads require an API key.
- Existing image links and embeds are not affected.
- If you hit a limit, uploads return a clear 429 error with a link back to this page.
ShareX Profile & API Keys
Generate your personal ShareX profile with a nickname at /sharex/profile. Your nickname appears in the admin panel so abusive API keys can be disabled individually.
What is planned next
- Unique API keys with fair daily quotas.
- Optional paid tiers for higher limits and larger file sizes.
- Better upload and album management for paid users.
