These limitations are estimates and may not prevent all performance issues, crashes, or failures
  • Device-Specific Restrictions: Mobile devices, tablets, and lower-specification computers have reduced limits to prevent crashes and ensure stability. Limits may be more conservative than what some devices can theoretically handle
  • Variable Performance: Individual device performance varies significantly based on model, age, specifications, RAM, CPU, running applications, browser version, extensions, system load, thermal state, and power mode
  • Processing Near Limits: Operations near or at maximum limits may result in slow performance, high resource usage, system instability, overheating, prolonged completion times, or failure to complete
  • Dynamic Adjustments: We reserve the right to adjust, modify, add, remove, or change these limitations at any time without notice based on performance data, user feedback, or technical considerations
  • No Completion Guarantee: We do not guarantee that any operation will complete successfully, even within stated limits. Completion depends on numerous factors beyond our control including device condition, browser state, available resources, and system stability
Background Processing and Mobile Limitations: On mobile devices, tablets, and environments with aggressive power management:
  • iOS/Safari and iPadOS: Processing may pause, stop, restart, or fail when the browser tab becomes inactive, app goes to background, device locks, screen turns off, or system enters low-power mode. Keep screen active, app in foreground, and device unlocked during operations. Safari may also limit memory available to inactive tabs
  • Android/Chrome: Background processing may be interrupted, throttled, delayed, or terminated by the operating system's memory management, battery optimization, doze mode, app standby, background execution limits, or adaptive battery features. Some devices may kill background processes aggressively
  • Screen Lock and Power Management: Device screen lock, auto-lock, sleep mode, power-saving features, or low-power mode may interrupt, suspend, or terminate processing. Disable auto-lock, keep device awake, maintain adequate charge level, and preferably connect to power during large or lengthy operations
  • Tab Switching and Multitasking: Switching to other tabs, apps, or performing other tasks may deprioritize, throttle, or suspend processing, significantly increasing completion time, causing failures, or triggering system resource management
  • System Interruptions: Incoming calls, video calls, notifications, alarms, system updates, app installations, or other system-level interruptions may pause, disrupt, or terminate processing on mobile devices and tablets
  • Long Operations on Mobile: We cannot guarantee completion of long-running operations (typically more than 2-3 minutes) on mobile devices or tablets due to aggressive power management and system resource controls
  • Recommendation: For large files, intensive operations, or lengthy processing tasks, use desktop or laptop computers with stable power connections and adequate cooling
Device Performance and Physical Impact: Tools that perform computationally intensive operations (including but not limited to file processing, multi-algorithm calculations, bulk conversions, data transformation, compression, decompression, encoding, decoding, cryptographic operations, media processing, image manipulation, batch operations, or complex computations) may cause:
  • Device Heating: Extended or intensive processing may cause smartphones, tablets, laptops, or desktop computers to heat up significantly, potentially affecting device longevity, user comfort, triggering thermal throttling, activating thermal protection mechanisms, or in extreme cases, causing thermal shutdown
  • Battery Drain: On mobile devices, tablets, and laptops, intensive processing may rapidly and substantially consume battery power, potentially draining battery from full to empty in a short time, requiring immediate connection to power source for completion, or affecting long-term battery health
  • Performance Degradation: System slowdown, browser freezing or hanging, UI unresponsiveness, input lag, frame drops, or temporary complete loss of control during processing operations. System may become unusable for other tasks during processing
  • Resource Exhaustion: High CPU usage (potentially 100% for extended periods), excessive memory consumption, disk I/O bottlenecks, or GPU usage may affect other applications, browser tabs, system services, background processes, or overall system stability
  • Browser or System Crashes: Processing large files, using many options simultaneously, or performing intensive operations may cause browser tabs to crash or become unresponsive, entire browser to crash or freeze, system-wide slowdown, or in severe cases, operating system instability, resulting in loss of all unsaved work, data, progress, or other open applications' state
  • Mobile Data Usage: Initial loading of tools, JavaScript libraries, cryptographic libraries, and other resources may consume significant mobile data (potentially several megabytes per tool). While processing is typically done locally without additional data transfer, ensure you have adequate data allowance if not on Wi-Fi
  • Fan Noise and Power Consumption: On laptops and desktop computers, CPU-intensive operations may trigger cooling fans to run at maximum speed for extended periods, increasing noise levels, power consumption, and potentially affecting nearby persons in quiet environments
  • Display and Screen Concerns: Keeping screens active for long operations may contribute to screen burn-in on OLED/AMOLED displays or increased power consumption. Users should monitor their devices during lengthy operations
We accept no responsibility for any device damage, hardware wear, component degradation, battery health reduction, thermal issues, overheating incidents, thermal throttling, fan wear, system instability, shortened device lifespan, or any physical, performance, environmental, or health-related impact on devices or users resulting from the use of these tools.
