Questions
Are my images uploaded?
No. Each image is converted inside your browser and never leaves your device.
Which format should I choose?
JPG for photos and anywhere that asks for JPG: small files, no transparency. PNG for screenshots, logos and anything with sharp edges or a transparent background. WEBP is smaller than both and suits websites, but some older programs cannot open it.
Can I convert several images at once?
Yes, up to 50 at a time. One image downloads on its own; several arrive together in a .zip.
What about HEIC photos from an iPhone?
Most browsers cannot read HEIC yet. On an iPhone, Settings → Camera → Formats → Most Compatible saves new photos as JPG.
