All paid plans give you access to a wide range of professional tools for developers, SEOs, designers, and digital specialists - including converters, formatters, SEO utilities, web scanners, and PDF tools. Every plan upgrades your daily usage limit and file capacity, and includes ad-free usage so you can work faster without interruptions.

Each time you run a tool (for example: JSON validation, SEO check, PDF conversion), it counts as one usage. Your plan determines how many tool operations you can perform per day. The count resets automatically every 24 hours.

API Access is available only for Enterprise plans and allows developers to programmatically use certain tools - for example verifying domains, generating hashes, converting formats, or retrieving IP / DNS info - directly from scripts or backend applications. If you run automations or build services on top of StackedTools, you need API access.

Yes. You can upgrade or downgrade your subscription at any time. The change will apply immediately and your usage limits will adjust accordingly. For yearly plans, we offer pro-rated adjustments.

If you reach the limit for your plan that day, you won’t be able to run additional tools until the next reset period (24h). Alternatively, you can upgrade your plan instantly to increase limits.

No. Usage counts reset every 24 hours. Unused daily quota does not accumulate - which ensures fair resource allocation across users.

No. You can use many tools for free with limited functionality and ads. If you need extended daily usage, larger files, or ad-free environment, you can choose a paid plan.

Files processed by tools - like PDF conversions, image formats, OCR, compressions - are automatically and permanently deleted after processing. No storage, no retention, no reuse - your data remains private.
