Add Text or Logo Watermarks to Images Online

An image watermark is a visible text mark, logo, signature, or graphic placed over a photograph or design. People use watermarks to identify the creator, show a brand name, add a website address, label a draft, or make it clear that an image is a preview. A watermark can remain subtle in a finished portfolio image or become more noticeable when you are sharing a proof that should not be mistaken for an unrestricted final file.

TinyImageResizer's Add Watermark tool lets you place custom text or an image logo over one or more photos. You can edit the text style, choose colors and opacity, move and resize the mark on the preview, rotate it, add multiple watermark elements, or repeat the chosen elements across the image with Mosaic / Tile Mode. When you add several source photos, the same watermark arrangement is applied to the batch and the finished files can be downloaded together in a ZIP archive.

A visible watermark is a practical attribution and branding layer, not a technical lock. It may discourage casual reuse and make ownership or authorship more obvious, but it cannot prevent every person from cropping, covering, or editing the mark. Keep the original unwatermarked image and treat the watermark as one part of a wider content and rights-management workflow.

A text watermark is useful when you want to display a photographer's name, studio name, social handle, copyright line, website address, product label, or draft notice. You do not need to create a separate graphic before adding a simple text mark. Choose Add Text, select the new element, and double-click the text on the preview to edit its wording. For the first watermark, the editor displays sample text that you can replace with your own.

The text toolbar includes a selection of font families such as Arial, Impact, Verdana, Courier, Times New Roman, Georgia, Montserrat, and Roboto. You can adjust the font size and apply bold, italic, or underline styling. Use the text-color palette to choose a readable color, and use the background-color control when the mark needs a solid block behind it. The background can also be set to transparent so only the letters are visible.

Text alignment can be set to left, centre, or right. This is helpful for longer copyright lines or a short brand name placed inside a wider text box. The selected watermark can be duplicated when you need another copy, or removed from the Elements list when it is no longer needed. You can create different text elements for a copyright line, a website address, and a small brand label, then position each independently on the preview.

For example, a photographer might use “© Alex Morgan Photography” as a small lower-corner label. An online shop might add “Official Store” or a short shop name to product photos. A designer sharing a draft may use “SAMPLE” or “PREVIEW” as a visible reminder that the image is not the approved final artwork.

Choose words that identify the source or status without hiding the subject.

A logo watermark uses an image instead of typed text. Choose Add Image and select the logo file you want to place over the source photograph. A transparent PNG is often a good choice for a logo because it can show the logo artwork without a solid rectangular background. A logo with a solid background can still be used, but its background will be part of the image that is placed over the photo.

After the logo loads, it appears as a selectable element on the preview. Drag it to the position you want. Use the resize handles around the selected element to make it larger or smaller, and use the rotation handle above it to change its angle. The opacity setting controls how strongly the logo appears over the photograph. A lower opacity can make a large logo less intrusive, while a higher opacity can make a brand mark easier to recognize.

You can add more than one image watermark if your layout requires a logo and a secondary mark. The Elements list shows the text and image items that have been added. Select an item in that list to edit or move it, duplicate it to create another copy, or remove it when it is not needed. The final image is rendered with the selected text and image elements combined on the source photo.

Placement is important because a mark should be visible without making the photograph difficult to understand. In the editor, select a watermark and drag it directly on the preview to position it. The editor provides resize handles around the selected element and a separate rotation handle. This gives you direct placement control instead of requiring you to enter fixed coordinates.

Opacity describes how transparent the watermark looks. The control ranges from 5% to 100%. At a lower setting, the original photograph remains more visible through the mark. At 100%, the watermark is fully opaque. A moderate opacity is often a useful starting point for a logo or signature, but the right value depends on the background, watermark color, and purpose of the image. Review the preview over both bright and dark areas before exporting.

For text, use a contrasting color that is easy to read. White text can work over a dark area, while dark text is often more visible on a bright background. A background-color block can improve readability when the photograph contains a mixture of light and dark details. Bold text can make a short name or handle clearer at a small size. Italic or underline styling can be useful for a particular visual identity, but too many styles together can make a watermark look crowded.

The preview also has zoom controls so you can inspect the placement at different magnifications. Zoom changes the editor view; it does not mean the downloaded image is exported at the zoomed preview size.

The watermark baker creates a canvas using the source image's pixel dimensions, applies the overlay elements at the corresponding scale, and exports the resulting image. A quarter-turn rotation of the source photo changes the output width and height orientation; otherwise the watermark operation is intended to retain the source photo's pixel dimensions.

A single watermark in a corner can be appropriate for ordinary branding, but it may be easy to crop away. Mosaic / Tile Mode repeats the watermark elements across the image as a pattern. This is useful for proof images, sample artwork, catalogue previews, or photographs that should show attribution in more than one place.

To use it, arrange the watermark element or elements on the preview, then enable Mosaic / Tile Mode in the side panel before processing. The canvas baker repeats the configured elements at intervals across the source image. This creates multiple visible marks rather than a single corner label. Review the preview and consider whether the repeated pattern makes the photo too difficult to inspect. A tiled watermark should discourage casual reuse without making the underlying subject completely unreadable when the image is being shared for review.

The current interface offers a simple on/off tile setting. It does not expose a separate spacing slider or a numeric tile-density field. The repeated spacing is determined by the tool's rendering logic. If you need a very specific grid interval, custom row count, or a different pattern for every individual photo, use a dedicated graphics editor that exposes those controls.

The tool can load multiple source images in the same workspace. You can move between them with the previous and next controls or choose a file from the image list. Set up the text and logo elements you want, choose their placement and opacity, and start Watermark Images. The same configured watermark arrangement is applied to each image in the current batch, with the watermark coordinates scaled to the output image dimensions.

Batch watermarking is useful when a photographer needs to mark a set of proofs, a shop owner wants a consistent brand mark on product photos, or a creator is preparing several images for a portfolio. Instead of adding the same name or logo separately to every file, you configure the watermark arrangement once and process the selected photos together.

When more than one result is ready, the tool creates a ZIP archive containing the watermarked images. You can also download an individual result from the result grid. Keep the original files until you have checked the exported copies, especially when the images are part of a product catalogue, a client delivery, or an important portfolio. If every photo needs a different position or a different watermark message, process those images in separate batches so the shared settings do not produce the wrong mark on some files.

The image picker accepts JPG, JPEG, PNG, GIF, and WebP source files. The watermark process uses the browser's image and Canvas APIs to combine the original photo with the selected text or logo elements. The current export logic creates a JPEG file when the source file is JPEG. For other accepted source types, it creates a PNG file. There is no separate output-format selector or JPEG-quality slider in this tool.

This difference matters when choosing a source. A JPEG photo is exported as JPEG. A PNG source is exported as PNG, which is suitable when transparency needs to remain in the image. A WebP source is exported as PNG rather than WebP. A GIF source is drawn through the browser's image element and exported as a still PNG; the original animation is not retained by this Canvas export path. The image dimensions are based on the source dimensions, with width and height exchanged when the base image is rotated by a quarter turn.

Because the result is rendered through Canvas, source metadata such as EXIF camera details is not carried forward as a full metadata-preserving copy. If you need to retain GPS, camera, copyright, or other embedded metadata, check the exported file with a metadata viewer and use a dedicated metadata workflow when necessary. Always open a downloaded file once to confirm that it displays as expected and has the format you need.

A watermark can communicate attribution, identify a brand, and make casual reuse less attractive. It does not encrypt the image, prevent screenshots, or create a guarantee that the picture cannot be copied. A person may crop a corner mark, cover a logo, or use image-editing tools to remove visible text. A repeating watermark may be harder to remove cleanly, but it can also interfere with viewing the image.

Use a watermark that suits the reason you are sharing the picture. A small signature can be enough for a public portfolio. A client proof may need a more visible repeating label. A product image may need a subtle logo that does not obscure the item being sold. Keep an original master file without the watermark so you can create a different version later, change the placement, or prepare a clean image for a customer who has permission to use it.

The watermark rendering function loads the selected image and watermark assets into the browser, draws them to an HTML canvas, and creates downloadable image blobs. The source code for this watermark-baking path does not send the photo to a TinyImageResizer image-processing endpoint. If you choose the optional Google Drive or Dropbox picker, that selection is handled through the connected provider's integration; direct device upload and watermark rendering use the browser workspace.

The tool creates a new watermarked copy rather than writing changes back into the original file on your device. Keep your source image separately if you may need an unmarked version later. Very large image batches can use substantial browser memory, so processing a smaller group at a time may be more reliable on a device with limited memory. If an image fails to load or export, try a common JPG or PNG copy and process fewer files in the batch.

Start with a short name, logo, website address, or copyright line rather than a long paragraph. Choose a color that contrasts with the image, then reduce opacity until the mark is visible without dominating the subject. Put a single brand mark near an edge for ordinary attribution, but remember that a corner mark can be cropped. For a draft or proof, consider Mosaic / Tile Mode and inspect how the repeated marks affect readability.

Before processing a batch, review the selected watermark elements and make sure the same wording and arrangement make sense for every photo in that group. If the images need different messages or placements, split them into separate batches. After exporting, open the downloaded files, check the dimensions and format, and retain the original unwatermarked images for future editing.
