When it helps

When product photos, blog images or social posts all need the same size, opening an editor for each one takes forever. This tool applies one size and one watermark to every photo at once.

There are three fit modes. Fit inside shrinks the photo to fit the box without cropping. Fill covers the whole box and crops from the center. Pad keeps the full photo and fills the leftover space with a color, which is handy for square feeds.

The watermark can be text or a logo image in any of nine positions, or tiled across the whole photo. It is a simple way to protect your work or product photos from being reused without permission.

FAQ

Are my photos uploaded to a server?

No. Resizing and watermarking both happen inside your browser, so your photos are never sent anywhere.

How many photos can I do at once?

There is no fixed limit. Because it uses your device memory, splitting hundreds of high-resolution photos into a few batches is more reliable.

What is the watermark size based on?

It is a percentage of the shorter side of each photo, so the watermark looks about the same on photos of different sizes.

Can I make small photos bigger?

Turn off Do not enlarge beyond original. Enlarging cannot add detail, so the result may look soft. For a sharper result, try the image upscaler.

The result is bigger than the original.

Saving as PNG or at high quality can increase the size. For photos we recommend JPG or WEBP at 80 to 90% quality.
