Utilavo provides a comprehensive collection of free tools organized into three categories. Every tool works directly in your browser or through secure server-side processing, with no account creation, no software installation, and no watermarks on your output files.
PDF Tools
Merge, split, compress, rotate, watermark, convert, protect, and organize PDF documents. Browser-based tools keep your files private; server-based tools handle complex operations like compression and format conversion.
Image Tools
Resize, crop, compress, rotate, watermark, and convert images across 8 formats including JPG, PNG, WebP, AVIF, HEIC, GIF, TIFF, and BMP. Images are processed on our servers and deleted right after download.
Developer Tools
Format JSON, encode Base64 and URLs, generate cryptographic hashes and HMACs, test regular expressions, convert colors and timestamps, and encrypt data with AES, DES, and more. All tools run in your browser with zero data transmission.

Getting started
Every tool on Utilavo is completely free with no account required. Many tools process your files entirely in your browser, meaning your data never leaves your device. Tools that require server-side processing (PDF compression, document conversion, all image tools) transfer files over encrypted HTTPS and delete them immediately after your download completes. There are no usage limits, no watermarks, and no features locked behind a paywall. For more details about how Utilavo works, visit the About page.
