Watermark image
Add a text or logo watermark to one photo or many at once. Drag the mark into place, set opacity and rotation, or tile it across the frame, then export at full resolution—or download a ZIP from bulk mode.

Pillar guide: How to Add a Watermark to Images Without Ruining the Photo
A watermark balances two goals: discourage reuse and stay readable without ruining the photo. Opacity around 35–60% usually marks ownership while keeping the subject visible.
Place a single mark in a corner for light branding, or tile it diagonally across the frame when you want to make cropping it out impractical—common for proofs, previews, and unreleased work.
Everything runs in your browser, so client proofs and unpublished assets stay on your device. Export keeps the original image resolution with the watermark baked in.
Watermarking signals ownership and discourages casual reuse of photos, proofs, and previews. The hard part is balance: a mark strong enough to deter copying but light enough to keep the image usable for review.
This tool adds a text caption or an uploaded logo, then lets you control opacity, rotation, size, and placement. A tile mode repeats the mark diagonally across the whole frame so it cannot be cropped out easily.
Processing stays in your browser, so unreleased and client-confidential images are not uploaded to a server. Export keeps the original resolution with the watermark flattened into the file.
Watermarking workflow
- Upload one image or switch to Multiple images to process many at once.
- Choose a text watermark (with color and size) or upload a logo/PNG mark.
- Set opacity and rotation, then drag the mark or pick a corner/center preset—or enable tiling to cover the whole image.
- Export as PNG, JPG, or WebP at each source image's native dimensions (ZIP in bulk mode).
How Watermark Image works
One image and multiple images
- One image: upload, drag and drop, or paste one file (⌘V / Ctrl+V or the Paste button on the dropzone when focus is not in a text field), preview the result, then download.
- Use Change image to swap the photo without leaving the tool, or Start over to clear the session.
- Multiple images: drag and drop or select many files; the same watermark settings apply to every item in the queue. Download a ZIP when processing finishes.
- In multiple-images mode, add more files anytime from the summary bar; changing settings reprocesses the queue automatically.
- Switching between One image and Multiple images clears the other mode so files and results do not mix.
Text and logo watermarks
- Type: Text for a caption, copyright line, or URL; Logo to upload your own mark (PNG with transparency works best, or any image format the browser decodes).
- Text mode: enter your caption, pick a color, and set Text size as a percentage of image width (2%–20%).
- Logo mode: upload or replace the logo, preview it, and set Logo width as a percentage of image width (5%–80%).
- Export requires watermark text in Text mode or an uploaded logo in Logo mode.
Opacity, rotation, and placement
- Opacity (5%–100%) and Rotation (−90° to +90°) apply to both text and logo marks.
- Placement — Single: one mark you can drag on the preview or snap to a corner/center preset.
- Placement — Repeat: tiles the mark edge to edge; adjust Spacing (0%–40%) to control gap between repeats.
- Placement — Diagonal: same as Repeat with a fixed −45° angle—a quick preset for proof-style coverage.
- In Single placement, pick Snap to corner presets or choose Custom — drag on preview for free positioning.
- Drag handles are hidden while Repeat or Diagonal is active because the mark covers the whole frame.
Preview, stats, and download
- One image mode shows Original vs Watermarked file size and confirms Same resolution (export uses full pixel dimensions).
- The canvas preview updates as you change settings; a short debounce runs before the download-ready export blob is ready.
- Export format: PNG (default), JPG, or WebP—PNG keeps crisp logo edges; JPG/WebP usually produce smaller files.
- Multiple-images mode shows per-card previews, paginates large queues, summary totals, and Download ZIP for finished files.
- In multiple-images mode, position uses preset pills—the same corner or center for every file (no per-image drag).
Input formats and privacy
- Upload any image your browser can decode—JPG, PNG, WebP, GIF, HEIC, HEIF, AVIF, JXL, SVG, and others.
- Processing stays in your browser—files are not uploaded to a server.
- A visible watermark is a deterrent, not copy protection; this tool does not embed invisible or forensic metadata marks.
Common use cases
- Photographers sending proofs or previews before final delivery.
- Designers and agencies sharing unreleased concepts with clients.
- Brands stamping a logo on product or campaign images before posting.
Practical tips
- Keep opacity around 35–60% so the mark is visible without hiding the subject.
- Use tiling with a slight diagonal rotation when discouraging crops or screenshots matters most.
- Export PNG when a logo has transparency or crisp edges; JPG/WebP keep files smaller for the web.
Limitations to know
- A visible watermark is a deterrent, not DRM—determined users can still edit or clone it out.
- Multiple-images mode uses position presets (not per-image drag); use One image mode to fine-tune placement on one photo.
- Does not embed invisible or forensic metadata watermarks.

Frequently asked questions
Can I watermark with my own logo?
Yes. Switch to the Logo mode and upload a PNG (transparency supported) or any image. Adjust its size and opacity, then position or tile it.
How do I cover the whole image so it can't be cropped out?
Choose Repeat or Diagonal under Placement. The watermark repeats edge to edge; Diagonal applies a fixed −45° angle for proof-style coverage.
Does the watermarked file keep the original resolution?
Yes. The preview scales to fit your screen, but export uses the source image's full pixel dimensions with the watermark applied.
What's the difference between Repeat and Diagonal placement?
Repeat tiles your mark across the whole image—you control spacing and rotation freely. Diagonal is a one-tap preset: Repeat plus a fixed −45° angle, common for proofs where you want edge-to-edge coverage quickly.
