Settings

Resize, add the watermark and optionally compress in one run. A size target requires JPG or WebP. Review text visibility before publishing.

Animated inputs become a still image. Large inputs are limited to 40 megapixels and are scaled down to at most 16 megapixels for output.

Put your own mark on a photo batch

Use a short text label or choose a PNG, JPG or WebP logo. Set its position, relative size and opacity, then process the batch. You can also limit output width and set a file-size target for JPG or WebP.

Watermarks are drawn into the exported pixels. They do not prevent copying or guarantee ownership. Check contrast and placement on each photograph. Transparent PNG logos work well; logos are limited to four megapixels.

Good to know

Do you upload or store my photos?

No. These tools read and process your selected images in your browser. Image content is not sent to our servers. Clear files or close the page to release the working session.

Why can the output be larger?

File size depends on dimensions, format and image content. PNG preserves pixels without a quality setting. Try WebP or JPG and a lower quality value when reducing file size is your priority.

Can I use HEIC, SVG, GIF or PDF?

Standard image tools support JPG, PNG and WebP. HEIC conversion and PDF tools are available on their own pages. SVG and GIF are not supported yet. Animated PNG or WebP images are flattened to a still image.

Are these tools free?

Yes. These tools work without an account, a watermark or a payment. Batch and resolution limits help keep processing manageable on your device.
