Hash Generator

Security Note: Passwords are generated locally using cryptographically secure random values. No data is sent to any server. Use passwords of at least 12 characters with mixed character types for best security.

Security Note: Random strings are generated locally using cryptographically secure random values. No data is sent to any server. Useful for API keys, tokens, unique identifiers, and test data.

Security Note: Bcrypt hashing is performed locally in your browser using the bcryptjs library. No data is sent to any server. Bcrypt is designed to be slow and resistant to brute-force attacks, making it ideal for password hashing.

Security Note: Base64 is an encoding, not encryption. It does not protect data. All conversion is performed locally in your browser. No data is sent to any server. UTF-8 text (including emoji) is fully supported.

Privacy Note: Counting is performed locally in your browser as you type. No data is sent to any server. "Characters" counts every character including spaces, tabs and new lines. Emoji are counted as single characters.

Privacy Note: Case conversion is performed locally in your browser as you type. No data is sent to any server. Title and sentence case understand Unicode letters, and camelCase, snake_case and kebab-case split existing words automatically.

Privacy Note: Encoding and decoding happen locally in your browser — images never leave your device. Note that Base64 inflates data by ~33%, so large images produce very long output. Recognized formats: PNG, JPEG, GIF, WebP, BMP and SVG.

Privacy Note: Resizing happens entirely in your browser using the HTML canvas API — images are never uploaded. Add up to 50 images (10 MB each). Output is re-encoded, so animated GIFs become a still frame and formats the canvas cannot encode are exported as PNG. Social Media presets center-crop to the exact size. Maximum output dimension is 10,000 px.

Privacy Note: PDFs are parsed and rendered entirely in your browser with PDF.js — files are never uploaded. Page mode renders each selected page; Extract images pulls embedded raster images out of the PDF and is best-effort for unusual masks, tiling, or unsupported image codecs. JPG output fills transparent areas with white. Maximum output dimension is 10,000 px.

Privacy Note: Images are combined into a PDF entirely in your browser with pdf-lib — nothing is uploaded. JPG and PNG files are embedded without unnecessary recompression. Drag cards to reorder them, or use the arrow buttons. Fit mode creates a page for each image; A4 and Letter scale images proportionally inside the selected margins.

Privacy Note: The PDF is parsed with PDF.js and the Word file is assembled entirely in your browser — nothing is uploaded. Password-protected PDFs prompt for their password locally. This is a text extraction, not a layout-perfect converter; scanned pages without a text layer need OCR first.

Privacy Note: Splitting is performed entirely in your browser with pdf-lib — the PDF never leaves your device. Password-protected inputs prompt for their password locally. Use custom ranges to extract chapters or selected pages into separate PDFs.

Privacy Note: PDFs are merged locally with pdf-lib in the order shown — nothing is uploaded. Password-protected files prompt for their passwords in your browser. Use the arrow buttons to move a file up or down before merging.

Privacy Note: Watermarks are drawn with pdf-lib directly in your browser — the PDF is never uploaded. Watermarks are visual overlays, not digital rights management. Standard PDF fonts support Latin characters; decorative scripts and some symbols may not render.

Privacy Note: Encryption uses AES-256 and happens entirely in your browser with pdf-lib — your file and password never leave your device. There is no password recovery: keep the password safe. Some PDF readers may ignore permission flags even when encryption is applied.
