Add Text Watermark to Images — Free Online Tool

Overlay custom text on photos with adjustable opacity (10–90%). Export JPEG, PNG, or WebP on XConverters — browser-local, free, no upload.

Protect and brand your photos with a text watermark using our free watermark image tool on XConverters. Default text is © XConverters — customize it, set opacity from 10% to 90%, and download JPEG, PNG, or WebP output entirely in your browser. No account, no upload, completely free.

What This Tool Does

Watermarks deter casual copying and signal ownership on portfolio shots, stock previews, and social posts. A semi-transparent text overlay across the image makes reuse obvious while keeping the picture visible for review. Our tool renders your caption on the canvas locally so you control wording and strength without Photoshop.

Opacity ranges from 10% for subtle credits to 90% for strong preview protection. Choose JPEG, PNG, or WebP export depending on whether you need transparency or smallest file size. Processing stays on XConverters in your browser — client photos and unreleased campaign assets never upload to a server.

The default © XConverters label demonstrates placement; replace it with your name, studio, or URL. Free, instant, and no registration — ideal for photographers, designers, and marketers who need quick branded exports.

How to Use

Add a text watermark on XConverters:

  1. Open the Watermark Image tool on XConverters — free with no account.
  2. Upload the photo you want to watermark.
  3. Edit the watermark text field — default is © XConverters; enter your own caption.
  4. Adjust opacity with the slider between 10% and 90% for subtle or bold overlays.
  5. Select output format: JPEG, PNG, or WebP.
  6. Apply the watermark and preview the result in the browser.
  7. Download the watermarked image to your device.

Rendering completes locally. XConverters does not store your originals or watermarked exports on any server.

Privacy and Security

Everything runs locally in your browser on XConverters. Your input is never uploaded to our servers, stored in a database, or shared with third parties. We designed this tool for developers, designers, and everyday users who need quick results without sacrificing privacy.

Only anonymous site analytics may be collected to improve performance and usability. The actual text, files, or data you process never leave your device during normal use.

Private by design: Because processing happens entirely in your browser, you can safely work with personal photos, client documents, API payloads, and proprietary content without exposing it to cloud storage.

Supported Formats and Use Cases

Common watermark use cases on XConverters:

  • Portfolio previews: Discourage theft of high-res work while showing composition.
  • Stock photo drafts: Send client proofs with studio name at moderate opacity.
  • Social media: Brand exports before posting to Instagram or LinkedIn.
  • Event photography: Add photographer credit on same-day sharing batches.
  • Internal reviews: Mark mockups as DRAFT with low-opacity text.
  • Copyright notice: Place © plus year and owner on published stills.

Tips for Best Results

  • Use 20–40% opacity for visible but non-intrusive credits on finished work.
  • Use 70–90% opacity for proof images that must not be used commercially.
  • Short text reads better than long URLs at small mobile sizes.
  • Choose PNG or WebP if the base image has transparency you need to preserve.
  • Keep a non-watermarked master archived locally before exporting proofs.
