Watermark & Annotation Studio
Add text or logo watermarks and real annotations — blur, pixelate, arrows, highlights, and pen.
Place text or logo watermarks — singly or tiled across the whole image — and add real annotations: arrows, boxes, circles, highlights, freehand pen, plus blur and pixelation for hiding sensitive details. Every edit is rendered into the exported pixels, so the download contains exactly what you see.

Frequently Asked Questions
Are the annotations burned into the exported image?
Yes. Blur, pixelation, watermarks, and drawings are all rendered into the final PNG, JPG, or WebP during export — they do not vanish after download.
Can I hide sensitive parts of a photo?
Yes — draw a blur or pixelation region over any area. The pixels inside are genuinely blurred or block-averaged, so the information is not recoverable from the exported file.
Are my files uploaded to a server?
No. PDFMiniFly processes everything locally inside your browser. Your document never leaves your device, and once the app is installed it also works offline.
