Add Page Numbers to PDF Online
Add page numbers to PDF documents so readers can follow reports, manuals, assignments, and long notes more easily. Numbered pages can make printed documents simpler to reference and organize.
Free Online Developer Tools
Format HTML, CSS, and JavaScript code, or generate an MD5 hash for basic checksum tasks. These browser-based developer tools help you keep code readable and support everyday development work.
HTML Beautifier
Format HTML with consistent indentation to make markup easier to read and maintain. Review the formatted code before using it on a live website.
JavaScript Beautifier
Beautify JavaScript with consistent indentation and formatting. Make scripts easier to read, review, and maintain before using them in your project.
CSS Beautifier
Format CSS rules with consistent indentation to make stylesheets easier to read and maintain. Review the output against your project's coding conventions.
MD5 Hash Generator
Generate an MD5 hash from text for basic checksums and legacy compatibility. MD5 is not suitable for password storage or modern security-sensitive cryptographic use.
Online Image Compressor and Image Converters
Compress images for websites and sharing, or convert between supported image formats such as JPEG, PNG, and WebP. Check the final image quality and transparency before using the converted file.
Image Compressor
Compress supported images to reduce file size for websites, blogs, and sharing. Check the output quality after compression because results depend on the source image and settings.
JPEG to PNG
Convert JPG or JPEG images to PNG format for workflows that require PNG files. Conversion cannot restore detail already lost in a compressed JPEG.
PNG to JPEG
Convert PNG images to JPG format for broad compatibility and potentially smaller files. JPG does not support transparency, so transparent areas may be filled during conversion.
Convert WebP to PNG Online
Convert WebP images to PNG format for apps or workflows that require PNG files. Review the converted image before publishing or reusing it.
