About Sharesizer
Sharesizer is an independent project that makes everyday image tasks quick and private for content creators: resizing for social platforms, cropping, compressing, converting formats, editing photos, making QR codes, and testing YouTube thumbnails.
Why it works the way it does
- Private by design. Everything runs in your browser. Your images are never uploaded.
- No sign-up, watermarks or limits.
- Honest specs. Platform sizes change often. Each size guide shows the date it was last checked, and where sources disagree we say so.
Creator Guides
Alongside the tools, the Creator Guides share practical, honest advice for building a channel, including the real costs and timelines that many tutorials skip.
Found a mistake?
