How do I add a watermark to a photo without losing quality?

The watermark is drawn on a full-resolution copy of your image inside the browser and re-encoded once at the quality you pick. The original pixels underneath the watermark are untouched at high quality settings (0.9 to 1.0), and PNG output is always lossless. To keep maximum fidelity, keep quality at 0.9 or above and use PNG for graphics with sharp edges.

Can I use my own logo as a watermark?

Yes. Switch to Logo mode and upload a PNG, JPG, or WebP logo. A transparent PNG works best because only the artwork shows on top of your photo. Use the Logo size slider to scale it relative to each image's width, so the same setting looks proportional on a 4000 pixel photo and a 800 pixel photo.

How do I watermark 100 photos at once?

Drop the whole folder in, set the watermark once (text or logo, opacity, position, tile), then click Apply. Every image gets the exact same watermark and comes out as a ZIP file. There is no per-file cap besides your browser's memory.

What is the best opacity for a watermark?

For a subtle brand mark on published photos, 30 to 50 percent opacity is a good starting point. It is visible but does not fight the image. For anti-theft use where you want to make casual reuse pointless, combine 60 to 80 percent opacity with Tile mode and a 45-degree rotation across the whole photo.

Can a watermark be removed by others?

Honestly, a small corner watermark can often be cropped or cloned out by a determined editor. Watermarks that sit in the center of the image or repeat across it with Tile mode are much harder to remove cleanly because doing so would damage the subject. If you are watermarking to deter theft, prefer Tile plus a diagonal rotation over a tiny corner mark.

Is this watermark tool free?

Yes. No signup, no watermark on the output beyond the one you choose, no daily limit, and no email wall. Watermark as many photos as your browser can hold in memory.

Are my images uploaded to a server?

No. All decoding, drawing, and re-encoding happens inside your browser tab using the standard Canvas API. Your photos, your logo, and the watermarked results never leave your device. This matters a lot for a watermark tool because people often watermark original, unpublished work.

What image formats are supported?

Input and output are JPG (JPEG), PNG, and WebP. Each file keeps its original format on export, so a JPG stays a JPG, a PNG stays a PNG, and a WebP stays a WebP. Logos can also be JPG, PNG, or WebP.

Is transparency kept when I watermark a PNG or WebP?

Yes. PNG and WebP outputs preserve the alpha channel, so a transparent background stays transparent behind the watermark. JPG output has no alpha, so any transparent pixels in a JPG are flattened onto a white background before the watermark is drawn.

Add a watermark to images online, free

Brand a portfolio of photos with your name, protect product shots from casual theft, mark a batch of proofs with a client's initials, stamp a copyright line on artwork before posting to social media, or add a repeating tile pattern across an unreleased edit so it cannot be reused without permission. This free watermark tool runs entirely inside your browser tab, so JPG, PNG, and WebP files stay on your device from the moment you drop them in to the moment you download the result.

One watermark configuration applies to the whole batch, which is the common case: you pick the text or logo once, decide where it sits, how transparent it is, and how it rotates, and every photo in the batch is stamped the same way. A live preview updates on each change so you can dial in the exact look before exporting. The output is delivered as individual files or a single ZIP archive, ready to publish or ship.

How to add a watermark

Open the Add Watermark to Image tool, no signup needed.
Drop your JPG, PNG, or WebP photos, or click to select them.
Pick Text and type your line, or pick Logo and upload a PNG, JPG, or WebP mark.
Choose a position on the 9-cell grid, set opacity, rotation, and margin. Turn on Tile to repeat across the whole photo.
Click Apply, then download each file or the batch as a ZIP.

Text watermark vs logo watermark

A text watermark is the fastest option and often the right one. Type a copyright line, a name, a URL, or a short brand phrase, pick a color and a font size, and it renders using the same clean sans-serif the rest of the site uses. Text watermarks are readable on almost any background because you can tune color and opacity independently. They also scale cleanly to any resolution because the tool draws them at the image's native pixel size, not by scaling up a raster.

A logo watermark uses your own brand mark. Upload a PNG (best), JPG, or WebP file, then use the Logo size slider to control how wide the logo should be as a percent of the image width. A transparent PNG works best because only the artwork shows on top of the photo, no white rectangle around it. Both text and logo modes support the same position grid, opacity, rotation, and tile pattern.

Watermark many photos at once

The single most common use case is a folder of freshly edited photos that all need the same corner mark before going out. Drop them all in, set the watermark once, click Apply, and download watermarked-images.zip. Every image is processed at full resolution, no downscaling, and the watermark is scaled relative to each image's dimensions so a small proof and a full-resolution export both get proportionate marks. There is no per-file cap besides your device's memory, so batches of one hundred or more images are normal.

Tile watermark to protect photos

Photographers and small sellers often want a watermark that cannot simply be cropped off. Enable Tile and the watermark repeats in a grid across the entire photo. Add a 45-degree rotation and the pattern goes diagonal, which is the classic anti-theft look used by stock agencies. Because the mark is everywhere, removing it cleanly would require rebuilding large portions of the image, which is enough of a speed bump to deter casual reuse. For proofs shared with clients this is often better than a small corner mark.

Choosing opacity and position

Opacity controls how strong the watermark looks against the photo. A subtle brand mark on a public post usually sits at 30 to 50 percent, visible but not fighting the image. An anti-theft mark sits higher at 60 to 80 percent so it actually gets in the way of reuse. The 9-cell position grid covers every corner, every edge midpoint, and the center. A bottom-right corner mark is the friendliest default because it stays out of the subject and is easy to spot; a center mark plus tile is the strongest.

Watermark JPG, PNG, and WebP

Every input format is supported, and the output keeps the input format so a JPG stays a JPG, a PNG stays a PNG, and a WebP stays a WebP. That matters for transparency: PNG and WebP outputs preserve the alpha channel, so a graphic with a transparent background stays transparent behind the watermark. JPG has no alpha, so any transparent pixels in a JPG input are flattened onto a white background before the watermark is drawn. For JPG and WebP outputs the quality slider (default 0.9) controls the re-encode; PNG is always lossless.

Your photos never leave your device

Privacy matters more than usual for a watermark tool because people watermark unpublished, original work: portfolio selects, product proofs, artwork, client previews. Every other online watermark tool asks you to upload those files to a stranger's server, then trust them to delete afterwards. This tool skips that entire step. Decoding, drawing, and re-encoding all run inside your browser tab, powered by the standard Canvas API. Your files, your logo, and any embedded EXIF data stay on your device. Turn off Wi-Fi after the page loads and it still works.

Works on Windows, Mac, Android, and iPhone

Because the tool is a web page, it runs anywhere a modern browser runs: Windows 10, Windows 11, macOS, Chromebook, Linux, Android, iPhone, and iPad. EXIF orientation is honored first, so a sideways phone photo shows upright in the preview and the watermark lands where you expect. After watermarking, you can send the results straight to our Compress Image tool to shrink the file size for the web without touching the watermark itself.
