Frequently asked questions
Free online media tools for everyday work
ToolsMastar brings together the file tools people reach for every day: an image resizer and compressor for faster websites, format converters for JPG, PNG, WebP and AVIF, favicon and ICO generation, watermarking and captioning, and utilities such as QR code generation, Base64 encoding and file hashing.
Image and utility tools run directly in your browser using the Canvas and Web Crypto APIs, which means there is no upload queue and no copy of your file on our servers. Heavier jobs — animated GIF editing, video and audio conversion, and PDF processing — run on dedicated server workers powered by FFmpeg, Pillow, Gifsicle and PDF libraries, with strict size limits and automatic deletion.
Every tool has its own page with instructions, supported formats and answers to common questions. Use the search box above to find a tool by name, by file format such as “webp” or “heic”, or by task such as “compress” or “rotate”. To learn more about a format before converting, see the file format guides.
