No account is required. You can use all FlexKit tools immediately without any registration. Simply visit the tool you need and start using it right away.

Most tools can handle files up to 100MB efficiently. Larger files may take longer to process depending on your device's capabilities. All processing happens in your browser, so performance depends on your device's memory and processing power.

FlexKit works best on modern browsers including Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari (latest versions). We recommend keeping your browser updated for the best experience.

Many tools work offline once the page is loaded, as processing happens in your browser. However, you need an internet connection to initially load the website and access the tools.

FlexKit offers a wide range of PDF tools including merge, split, compress, rotate, unlock (remove password), convert to images, extract images, and more. All operations are performed locally in your browser.

No! All PDF processing happens entirely in your browser. Your files never leave your device, ensuring complete privacy and security. No data is sent to any server.

Yes! Our PDF unlock tool can remove passwords from PDF files. Simply upload your password-protected PDF and enter the password to unlock it. The unlocked PDF will be processed entirely in your browser.

Most PDF tools can handle files up to 100MB efficiently. Very large PDFs (over 100MB) may take longer to process, but the tools will still work. Processing time depends on your device's capabilities.

Yes! The PDF merge tool allows you to upload and merge multiple PDF files in any order. You can rearrange the files before merging to control the final document structure.

For most operations (merge, split, rotate), the quality remains unchanged. Compression tools may reduce file size with minimal quality loss, and you can adjust compression settings to balance quality and file size.

Yes! FlexKit includes tools to convert PDFs to images (PNG, JPG). Each page of the PDF is converted to a separate image file, which you can download individually or as a ZIP archive.

FlexKit supports all major image formats including JPEG, PNG, GIF, WebP, BMP, TIFF, and SVG. You can convert between these formats, resize, compress, and perform various other image operations.

Image quality depends on the operation. Format conversion and resizing maintain quality based on your settings. Compression tools allow you to adjust quality levels to balance file size and image quality according to your needs.

Yes! Many image tools support batch processing. You can upload multiple images and process them all at once. Results are typically provided as a ZIP file for easy download.

Image tools can handle images up to 100MB efficiently. Very high-resolution images may take longer to process, but the tools will work. Processing happens entirely in your browser.

No! All image processing happens locally in your browser. Your images never leave your device, ensuring complete privacy. No data is sent to any server or stored anywhere.

Yes! FlexKit includes comprehensive image format conversion tools. You can convert between JPEG, PNG, WebP, GIF, BMP, and other formats. The conversion maintains image quality based on the target format's capabilities.

FlexKit offers various text tools including word/character counter, text transformer (case conversion), password generator, QR code generator, Lorem Ipsum generator, Markdown preview, and text diff (comparison) tools.

Absolutely! All text processing happens entirely in your browser. Your text never leaves your device, ensuring complete privacy and security. No text is sent to any server or stored anywhere.

Yes! Text tools can handle documents of any reasonable size. Word counting, character counting, and text transformation work efficiently even with very long documents. Processing happens in real-time as you type.

Our word count tool is very accurate. It counts words by splitting on whitespace, which is the standard method used by most word processors. It also provides character counts with and without spaces.

Yes! The password generator uses cryptographically secure random algorithms to create strong passwords. You can customize length and character types (uppercase, lowercase, numbers, symbols) to meet your security requirements.

FlexKit includes various developer utilities such as JSON/XML/YAML/SQL formatters, file renamer, Base64 encoder/decoder, JWT decoder/encoder, cURL command builder, cron expression explainer, string escaper, and more.

Yes! FlexKit provides formatters for JSON, XML, YAML, and SQL. These tools can pretty-print (format with indentation), minify (remove whitespace), and validate syntax. All processing happens locally in your browser.

Yes! All JWT decoding happens locally in your browser. Your tokens never leave your device. However, be cautious when sharing decoded token contents, as they may contain sensitive information.

Yes! The cURL builder tool helps you construct cURL commands for API testing. You can specify HTTP methods, headers, body content, and other parameters. The tool generates the complete cURL command ready to use.

FlexKit developer tools are designed for development, testing, and debugging purposes. While they use secure algorithms and process data locally, always follow best practices for handling sensitive data in production environments.

Yes! FlexKit is designed with privacy as a core principle. All processing happens locally in your browser - your files, images, and text never leave your device. No data is uploaded to servers, stored, or shared with third parties.

No! We do not collect, store, or have access to any of your files, images, or text. All processing is performed entirely in your browser using client-side JavaScript. Your data never reaches our servers.

FlexKit uses minimal cookies only for essential functionality like language preferences and theme settings. We do not use tracking cookies or analytics that identify individual users. You can manage cookie preferences in the settings.

Yes! Since all processing happens locally in your browser, FlexKit is safe to use with sensitive documents. Your files never leave your device, making it ideal for confidential or private content.

We collect minimal information necessary for website functionality (language preferences, theme settings). We do not collect personal information, file contents, or usage data that could identify you. Our privacy policy provides full details.

Large files may take longer to process, especially on older devices. Try processing smaller files or closing other browser tabs to free up memory. If the issue persists, try a different browser or device.

Yes! FlexKit is responsive and works on mobile devices. However, processing large files on mobile may be slower due to limited processing power and memory. For best results, use desktop browsers for large file operations.

No installation required! FlexKit runs entirely in your web browser. Just visit the website and start using the tools. No downloads, installations, or plugins needed.

No browser extensions are required. All tools work directly in your browser without any additional software or extensions. However, some browsers may have extensions that enhance the experience, but they're optional.
