Are images uploaded to a server?
No. UploadReady V1 processes selected images locally in your browser and does not store them.
Is 300x300 good for profile photos?
It is fine for small avatars, but use 600x600 or larger when the platform displays bigger photos.
Will the output be square?
Yes. Exact dimensions and square crop are enabled by default.
Can I make a PNG instead?
Yes. Select PNG output, but the file may be larger than JPG.
What formats are supported?
V1 supports JPG, PNG, WEBP and best-effort HEIC/HEIF conversion where your browser and file allow it. PDF tools are intentionally not included in this first image-focused release.
