Frequently Asked Questions
Is my image uploaded to a server?
No — everything happens in your browser using the Canvas API. Your image never leaves your device and is never sent to any server.
What image formats are supported?
You can upload JPG, PNG, WebP, GIF and most other common image formats. You can output as JPG, PNG or WebP.
What does Lock Aspect Ratio do?
When locked, changing width automatically adjusts height proportionally (and vice versa) so your image is never stretched or distorted.
What quality should I choose?
90–95% gives near-lossless quality. 70–85% gives a good balance of quality vs file size. Below 60% is noticeable but very small files.
