Free Tools for TikTok, Instagram, Videos and Images
SocialTools is a small collection of single-purpose tools for the practical work that surrounds posting: writing a profile bio that explains what your account is about, finding a handle that is still free, drafting a caption that fits the video, grouping hashtags so a post reaches beyond your followers, and exporting media at the size each platform actually wants.
The generators are template-driven and run entirely on your device. They combine your own inputs — name, niche, keywords, tone and language — into several variations you can edit rather than paste blindly. The image compressor, WebP converter, image resizer and MP4 to GIF converter use the browser's Canvas and File APIs, so your photos and clips are processed locally and never uploaded.
The calculators answer the questions that come up right before an export: the aspect ratio calculator tells you the simplified ratio and orientation of any resolution, the file size calculator estimates how heavy a render will be at a given bitrate, and the Reels size calculator lists the recommended dimensions and safe zones for vertical video.
