About
Why social media tools exist
Every platform wants a different size, format and style — the same image that looks perfect on a feed gets butchered as a story. These tools handle the dimensions, captions and hashtags so you focus on the content.
Built for creators posting across multiple platforms who don't want to look up specs every time.
Which social tasks matter most?
- ✓
Correct dimensions — Wrong aspect ratios get cropped or letterboxed — size it once, correctly.
- ✓
Hashtags — A few well-chosen niche tags reach further than a wall of generic ones.
- ✓
Captions — The first line decides whether anyone taps "more".
- ✓
Thumbnails — On YouTube especially, the thumbnail is half the video's success.

Common mistakes
- ✗One image for every platform — stories, feeds and banners all need different sizes.

- ✗Ignoring the first line of a caption — everything after it sits behind "more".
Tips that actually help
- ✓Design for mobile first — the vast majority of social scrolling happens on phones.
- ✓Batch your assets — resize for all platforms in one session.
- ✓Preview how content crops before posting; safe margins matter.
FAQ
Social Media Tools — questions, answered
Which platforms are supported?+
Resizers cover Instagram feed, stories, profile pictures and YouTube thumbnails; generators work for Instagram, TikTok, X and YouTube content.
Do resized images keep their quality?+
Resizing uses your browser's rendering engine with high-quality scaling. For downscaling — the common case — output stays crisp.
Is downloading YouTube thumbnails allowed?+
Thumbnails are public images served by YouTube's CDN. Use them responsibly — respect creators' rights for anything beyond personal reference.
How many hashtags should I actually use?+
3–5 relevant, niche-specific tags consistently outperform walls of generic ones. Instagram allows up to 30, but relevance beats volume.
Why did my image get cropped on a platform?+
Each placement has its own aspect ratio — feed, story and banner are all different. Resize for the specific placement before posting.
