ConvertResize.com is a collection of free, browser-based tools for working with images, audio, video, and files. Born from the belief that essential digital tools should be free, fast, and respect your privacy, we've created powerful tools that run directly in your browser — with no sign-ups, no watermarks, and no hidden costs.
ConvertResize.com was created out of frustration with existing online conversion tools that were slow, required uploads to unknown servers, or came with hidden costs and watermarks. We built these tools to work the way we wished they existed - fast, private, and truly free.
Unlike many other "free" converters, our tools are designed to protect your privacy. All processing happens locally on your device. This means your files never leave your computer, tablet, or phone.
Our tools use modern web technologies like JavaScript, WebAssembly, and HTML5 APIs to process files entirely within your browser. This client-side approach means faster processing, better privacy, and no dependency on our servers for the actual file work.
Our tools work on any device that runs JavaScript, including:
Mobile: iPhone, Android phones, Samsung Galaxy, Google Pixel, OnePlus
Tablets: iPad, Android tablets, Samsung Galaxy Tab, Microsoft Surface
Computers: Windows PC, Mac (macOS), Linux, Chromebook
Browsers: Chrome, Firefox, Safari, Edge, Opera
Image Tools: Resize, crop, compress, split, create favicons, build photo collages, convert HEIC to JPG/PNG, and generate ASCII art
Audio Tools: Convert between MP3, WAV, OGG, M4A formats and compress audio files
Video Tools: Create GIFs from videos, extract audio tracks, and compress video files
Utility Tools: Transfer contacts between iPhone and Android, copy Spotify playlists, work with ZIP files, view file metadata, and convert phone keypad letters
