Frequently asked questions
Are my images uploaded?
No. Watermarking runs locally in your browser. No image data is sent to PIC.NET.
Can I watermark multiple images at once?
Yes. Add multiple images, apply one set of settings, then download all results in a ZIP file.
Will export change image dimensions?
No. Each result keeps the original pixel dimensions. JPG and WebP quality can be adjusted before export.
Can I use a transparent logo?
Yes. Transparent PNG and WebP logos are supported and their transparency is preserved.
