Browser-based tools for image, text, developer, video, and audio tasks
SupaTools.AI is a collection of free online utilities for working with images, text, code, video, and audio. The site combines multiple small tools in one browser-based hub, including format converters, OCR, JSON formatting, diff checking, and media conversion.
The main purpose of the product is to let people process files or text without uploading them to a server. According to the site, the tools run locally in the browser, require no sign-up, and are presented as private, fast, and free to use.
Core features
Image editing and cleanup
Resize images, compress JPG/PNG/WebP files, add text overlays, strip metadata, and extract text from images using in-browser OCR.
Developer utilities
Format, validate, and minify JSON, compare text diffs, generate passwords, and encode or decode Base64 for development workflows.
Video and audio tools
Convert or trim video and audio files, including video compression, video-to-GIF conversion, MP4-to-MP3, M4A-to-MP3, and audio trimming.
Local in-browser processing
All tools run in the browser using Canvas API, WebAssembly, or plain JavaScript depending on the workflow, so files are processed locally instead of uploaded to a server.
Practical ways to use SupaTools.AI
Prepare images for sharing
Convert common image formats, compress files, remove metadata, or resize graphics without sending source files to a server. This is useful for quick file preparation before sharing or uploading elsewhere.
Work with text and screenshots
Use the OCR and text tools to extract readable text from screenshots or adjust raw copy with counts, formatting, or transformations. This fits drafting, cleanup, and lightweight content analysis.
Handle developer text tasks
Format JSON, compare two blocks of text, encode or decode Base64, and generate passwords in a browser-only workflow. These are standard tasks for developers handling snippets, configs, or API-related text.
Convert or trim media files
Trim audio, convert M4A to MP3, compress video, or turn video clips into GIFs directly in the browser. That makes the site useful for simple media conversions and quick edits.
Keep files local while processing
Use the tools when privacy matters and you want to avoid uploading files to external services. The site positions local processing as the default workflow for both files and text.
