Questions & Answers

As answered by people managing ImageResizer and Upload-Post.

What makes your product unique?

Upload-Post's answer:

Upload-Post is the only API that lets you post to 10+ social platforms with a single endpoint. No need to integrate TikTok, Instagram, YouTube, and Facebook APIs separately — one call handles everything. We also offer true white-label: your users connect their accounts directly, so you never touch their credentials.

Why should a person choose your product over its competitors?

Upload-Post's answer:

  • One API, all platforms: Post to TikTok, Instagram, YouTube, Facebook, X, LinkedIn, Pinterest, and Threads without managing 8 different integrations
  • Developer-first: Clean REST API, webhooks, and native n8n/Zapier support
  • White-label ready: Let your users connect their own accounts — perfect for SaaS platforms
  • Reliable: We handle platform API changes, rate limits, and retries so you don't have to
  • Fair pricing: Start free, pay only for what you use

How would you describe the primary audience of your product?

Upload-Post's answer:

  • SaaS platforms adding social media publishing to their product
  • Marketing agencies managing multiple client accounts
  • Developers building social media automation tools
  • Content creators who want to post everywhere at once
  • No-code builders using n8n or Zapier for automation

What's the story behind your product?

Upload-Post's answer:

We were building a SaaS and needed to post to multiple social platforms. Integrating each API separately was painful — different auth flows, formats, rate limits, and constant breaking changes. So we built Upload-Post to solve it once. Now thousands of developers use it to skip the headache and ship faster.

    800x450 is 2.4 times smaller then regular HD quality (1920x1080), you can use https://imageresizer.com/ to resize your image. Source: over 3 years ago
  • Really new to this, not sure what I'm doing
    The bot's avatar image you're attaching might be too large. If that is the case use a service like https://imageresizer.com to shrink it to a reasonable size. Under 1MB is safe. Source: over 3 years ago
  • The Dark Side Of The Moon Mosaic [2560x1080]
    Windows PTs only has a simple resize tool. What you want is https://imageresizer.com/ that is mentioned in the sticky guide that has a crop function as well. I hope this helps :). Source: over 3 years ago
