Add Watermark

Add a text watermark online

Protect your work or brand photos with a visible text stamp — no Photoshop required. Batch mode applies the same watermark to every image.

How to watermark an image

1. Upload one or more JPG, PNG, or WebP images.
2. Adjust watermark text, size, color, opacity, and position — preview uses the first image.
3. Optionally enable tile mode for a repeated diagonal pattern.
4. Click Apply to all & download ZIP — or download each file from the results list.

What Add a Text Watermark does

This browser-based tool helps you watermark one or more images without installing desktop software or sending the selected file to an image-processing server. It creates copies carrying a visible text mark in a chosen position or repeated pattern. The editor is intentionally focused: it exposes the controls needed for this task and shows the result before you save it.

The available controls cover watermark wording, font size, colour, opacity, position and tiling. Use the original file when possible, review the preview at a useful zoom level and keep the untouched source after downloading. A browser tool can make the requested pixel operation convenient, but it cannot recreate missing detail or judge whether an image is suitable for every destination.

A reliable step-by-step workflow

1. Choose a clear source image in one of the formats shown by the upload field.
2. Wait for the preview to appear and confirm that orientation, colours and transparency look as expected.
3. Adjust watermark wording, font size, colour, opacity, position and tiling. Make one meaningful change at a time so it is easy to compare the result.
4. Inspect small text, faces, edges and transparent areas before downloading.
5. Save the result with a descriptive filename and keep the original separately.

If the destination specifies pixel dimensions, file weight or a particular format, check those requirements independently. Editing appearance does not automatically satisfy a size limit, and converting or compressing afterward may change the result again.

Understand the controls and downloaded file

The tool supports batch processing and preserves JPG, PNG or WebP output according to the source. A ZIP is available for a group of results.

The live preview is designed to show the intended visual result, while the downloaded file is the item to inspect before publishing. Browser previews may be scaled to fit the page, so open the saved file at 100% when sharpness, alignment or small lettering matters. Avoid repeatedly editing and saving a lossy JPG when you still have the original available.

Practical uses

• Identify preview photographs.
• Place a brand or creator name on a batch.
• Mark internal drafts before review.

The same operation can be part of a longer workflow. A typical sequence is to crop unwanted areas first, perform the creative change, resize to the final pixel dimensions and compress only at the end. This avoids spending processing time on pixels that will later be removed and lets you judge compression on the actual final image.

Quality, accuracy and important limitations

A visible watermark discourages casual reuse but cannot guarantee ownership enforcement or prevent removal. Keep original files and use appropriate rights-management practices when protection matters.

Image quality depends strongly on the source. A high-resolution original normally leaves more room for cropping and resizing, while a small screenshot or previously compressed download may already contain blur, ringing or block artefacts. Saving a new file cannot restore information that is absent from the source. When accuracy matters, compare the finished file side by side with the original.

Private browser processing and device performance

The selected image is processed locally by JavaScript and browser canvas APIs. The editing operation does not require the file to be uploaded to the Image Online Free server. This is useful for ordinary personal and work images, but you should still control where downloaded copies are stored and who can access your device.

Large images require more memory because the browser must decode the compressed file into pixels. A modern camera photo may occupy far more memory than its file size suggests. If a phone tab becomes slow, close unused applications, process one large file at a time or resize a copy before applying the effect.

Common mistakes to avoid

• Replacing the only copy of the original with an edited or compressed result.
• Judging sharpness only from a small fitted preview instead of opening the download.
• Assuming a visual edit also meets a website's dimensions or maximum file-size rule.
• Ignoring transparency when moving between PNG, WebP and JPG.
• Applying several lossy saves when the complete workflow could start again from the original.

Choose the next operation according to the final requirement. Resize changes pixel dimensions, crop removes part of the frame, compression targets file weight and conversion changes the file format. These are separate tasks, even when a destination asks for several of them together.

FAQ

Does the output format change?

No. JPG stays JPG, PNG stays PNG, and WebP stays WebP.

Can I watermark multiple images at once?

Yes. The first image drives the live preview; the same settings are scaled proportionally to each file's dimensions.

Can I repeat the watermark across the whole image?

Yes. Check Tile / diagonal repeat to stamp the text in a pattern over the entire photo.

Is my image uploaded?

No. Watermarking happens entirely in your browser.
