Watermark image online, free

1. Choose text or logo. Use the Text mode for a copyright line, name, or URL, or switch to Logo and upload a PNG or JPG of your brand mark.
2. Tune the look. For text, set the font size (as a percentage of the image width so it scales correctly), pick a color, and adjust opacity. For a logo, set its size and opacity the same way.
3. Pick a position. Use the 9-grid to anchor the watermark to a corner, edge, or the center, or choose Tile to repeat it diagonally across the entire image — the strongest option for deterring image theft.
4. Add your images. Drag and drop a single photo or a whole folder's worth onto the drop zone. The first image updates instantly in the live preview so you can fine-tune before committing.
5. Apply and download. Click Apply to all & download to render every image at its own full resolution, then grab files one by one or as a single Download all as ZIP.

Because everything happens in your browser using the HTML canvas API, there is no file size limit, no account, and no watermark left on the tool's own output — only the one you designed.

Both approaches protect your work, but they suit different situations. Here is how to decide:

Many photographers and brands combine both: a small logo in a corner for everyday sharing, and a tiled text watermark for preview or proof images that are more exposed to theft. Need to write directly onto a photo instead of stamping a repeatable mark? Try our add text to image tool.

• Corner placement (bottom-right is most common) keeps the watermark visible without covering the main subject — the standard choice for portfolios and client galleries.
• Center placement is the hardest to crop out, which makes it a good choice for preview/proof images you don't want reused before purchase.
• Tiled placement repeats the mark diagonally across the entire photo. It is the most theft-resistant option because there is no clean corner left to crop away, though it is also the most visually intrusive — best reserved for low-resolution previews rather than final delivered images.
• Edge placement (top or bottom center) works well for wide banner-style images where a corner mark would sit awkwardly close to the frame.

Whichever position you choose, keep opacity moderate — a watermark that is too faint won't deter reuse, and one that is too strong ruins the photo. 60–80% opacity is a reasonable starting point for most use cases.

• Protect your work. A visible mark makes it obvious an image is owned and discourages unauthorized reuse on social media, marketplaces, and other websites.
• Promote your brand. Every share of a watermarked photo doubles as free advertising — viewers see your name or logo attached to the work.
• Gate preview content. Photographers and stock contributors watermark proofs so clients can review images before paying for the clean, unmarked originals.
• Prove provenance. A consistent watermark style across a portfolio helps establish which images are genuinely yours if disputes ever arise.

Yes. Unlike most online watermarking services that require you to upload your photos to a server, this tool draws the watermark directly onto each image using the HTML canvas API inside your own browser tab. Your images and your logo file never leave your device, the tool works offline once the page has loaded, and nothing is stored, logged, or seen by anyone else. That makes it safe for unreleased product shots, client proofs, and personal photos alike.

• Photographers mark proof galleries so clients can preview a shoot before buying the unwatermarked, full-resolution files.
• E-commerce sellers stamp a small logo on product photos to prevent competitors from lifting images for their own listings.
• Content creators & bloggers add a username or site URL to images before posting so credit follows the photo wherever it is shared.
• Real estate agents brand listing photos with an agency logo across every property gallery.
• Stock and freelance artists tile a watermark across low-res previews to prevent unauthorized use before licensing.
• Small businesses batch-brand an entire folder of marketing images in one pass instead of editing each file individually in a design tool.

• Use a font size around 4–8% of the image width for corner text — large enough to read, small enough to stay out of the way.
• For logo watermarks, export your logo as a PNG with a transparent background so it blends naturally instead of sitting on a white box.
• Batch consistency matters: set your position, size, and opacity once, then apply the same watermark to every photo in a shoot so your galleries look uniform.
• If you plan to compress the watermarked images afterward, watermark first, then compress — that way the mark is baked into the final file at every size you export. Our image compressor is a natural next step.
