Batch watermark photos

Add your name or logo to up to 40 photos at once: in any corner, centred, or tiled across the frame, with the size and opacity you choose. It is free, needs no account, and works in your browser, so your photos are never uploaded. You get full-size JPEGs back in one ZIP.

Drop photos here, or click to choose

Up to 40 at a time. They're watermarked on your device and never uploaded.

Large batches of full-size photos can take a minute on older phones. Keep the tab open until the ZIP downloads.

When to watermark, and when not to

Watermark the photos that travel without you: previews you send before payment, proofing sets, and posts on social media or your blog. Don't watermark the final delivery your client paid for, and never watermark real estate listing photos, because MLS rules ban logos and text on them. For listings, use the MLS photo resizer instead.

Where to put it so it survives a crop

Instagram shows feed posts at 4:5 or 3:4, so a landscape photo gets cropped at the sides, and a mark sitting tight in a corner can vanish. For photos headed to social media, keep the watermark away from the edges: bottom centre, or a corner with a bigger margin. For a gallery or website, a small corner mark at low opacity stays out of the way.

A small mark, or tiled across the frame?

A small corner mark credits you without spoiling the photo, which is right for social posts. Tiled marks across the whole frame suit proofs, where you want the client to choose favourites but not screenshot a usable copy.

Be realistic about what a watermark does. It stops casual reuse and makes sure people know who took the photo, but someone determined can crop or retouch it out. Low-resolution previews protect you as much as the mark does.

Common questions

Are my photos uploaded?
No. Each photo is opened, stamped and saved again inside your browser tab, then downloaded straight to your device. Nothing goes to a server, so there is no file size limit beyond what your device can handle.
What size do the watermarked photos come out?
The same size as the originals by default, saved as high-quality JPEG. You can also cap the long edge at 2048px or 1600px, which suits websites and social posts.
Can I use my logo instead of text?
Yes. Choose Logo and add your logo file. A PNG with a transparent background looks cleanest; a JPEG logo keeps its background box.
Does it work with iPhone HEIC photos?
Yes. HEIC files are converted in your browser as they are watermarked, and come out as JPEGs.
Will it remember my settings?
Your text, position, size and opacity are saved in this browser, so the next batch starts where you left off. Logos aren't saved; add yours again each visit.

Deliver clean files, keep the previews protected

Your client should get photos without a mark on them. A GalleryLink gallery sends them one link to view and download the clean files, with a password on Pro. On the Studio plan ($15 a month), hosted galleries can show your watermark on the previews while downloads stay clean.
