FAQ

Resize vs compress — which should I use?
Resize changes pixel dimensions (or percent). Compress reduces file size in KB/MB while keeping the same layout. Many uploads need both: resize first, then compress.
Are preset sizes official platform dimensions?
Presets are practical guides. Platform requirements vary — confirm against each network after applying a preset. For social crops, try Social Media Sizes.
Is my photo uploaded?
No. Resizing runs in your browser on your device.
