Bulk watermark

Put your name, copyright or logo on a whole batch of photos in one go. See exactly how it looks on each picture before you start, then download everything as one ZIP.

Checked on every file

Each watermarked file is opened again: it must be the right format and size, unchanged outside the watermark, and the tool tells you where the mark is hard to see.

Ready. Images are watermarked on this device and never uploaded.
Add images or a folder to watermarkJPG, PNG, WebP, AVIF or HEIC. Up to 200 images at once; folders keep their structure in the ZIP.

    How it works

    Add, design, apply

    1. Add photos or a whole folder. JPG, PNG, WebP, AVIF or iPhone HEIC, up to 200 at a time.
    2. Design the watermark. Your text or logo, as one mark in a corner or repeated across the whole picture, with size, colour, opacity and angle.
    3. Check the preview. Step through your photos to see the watermark on each of them.
    4. Apply and download. Download single files or everything as a ZIP that keeps your folders.

    Which style?

    A corner mark or a repeated pattern

    One mark in a corner credits your work without spoiling the picture: good for portfolios, social media and product photos. It can be cropped off, though.

    Repeat across covers the whole picture with a faint diagonal pattern. It is much harder to remove or crop, which makes it the better choice for proofs sent to clients, photos of documents and images you need to protect.

    Good to know

    Sizes that fit every photo

    Text size is set as a share of each photo's shorter side, and a logo's width as a share of the photo's width, so one design looks the same on a small phone photo and a large camera file. The contrast outline keeps white text readable on bright skies. Location and camera data are not copied into the watermarked files.

    FAQ

    Questions about watermarking.

    How do I watermark many photos at once?

    Add all the photos, or a whole folder, design the watermark once, and choose Watermark images. Every photo gets the same design, scaled to its size, and you can download them all as a ZIP.

    Can I use my logo as a watermark?

    Yes. Choose Logo and add your logo; a PNG or SVG with a transparent background looks best. Set its width and opacity, and place it in a corner or repeat it across the photo.

    Will the watermark look the same on photos of different sizes?

    Yes. Sizes are proportions of each photo, not fixed pixels, so the watermark covers the same share of a 2-megapixel phone photo and a 40-megapixel camera file. Use the preview arrows to check it on each photo.

    Does watermarking reduce the quality?

    Only where the watermark is. Photos are saved at high quality (92 for JPG and WebP by default), and the tool checks that everything outside the watermark is unchanged. PNG files are saved without any loss.

    Can a watermark be removed?

    A single corner mark can be cropped out, and any watermark can be retouched with enough effort. A repeated pattern across the whole picture is much harder to remove, so use it when protection matters more than looks.

    Are my photos uploaded?

    No. Watermarking happens in your browser, and your photos, logo and text never leave your device. Location and camera data are not copied into the new files.
