Watermark & convert photos
Right in your browser
Stamp your logo on a whole batch of photos, or convert JPEG, PNG, and WebP. Free, with no signup — your files never leave your device.
Why We Exist
Watermark your work. Keep your photos.
Photographers, small shops, and creators should not need a subscription to protect a batch of photos or to change a file format.
Everything runs in your browser, on your own device. Your photos are never uploaded, and downloads are always free.
No signup or payment required. Buy Me a Coffee is entirely optional.
Three steps. No account. No waiting.
Step 1: Add Your Images
Drop a batch of photos and your logo.
Or pick the formats to convert.
Nothing is sent to any server.
Step 2: Adjust
Place your logo in a corner or tile it diagonally.
Pick an output format and quality.
The live preview shows the selected photo.
Step 3: Download
Download one image or the whole batch as a ZIP.
Work runs on download, at full resolution.
No watermarks added by us. Ever.
Two tools, zero uploads.
Bulk Watermarking
One logo applies to your whole batch. Place it in any of nine positions with size, margin, and opacity controls.
Tiled Overlay
Rotate the whole layer up to 45° and tile your logo across the photo — the diagonal stock-photo protection style.
Format Converter
Convert between JPEG, PNG, and WebP, one file or a hundred. Each direction has its own dedicated tool page.
Quality Control
Choose the JPEG or WebP quality when converting. PNG output stays lossless.
Metadata Stripped
Canvas re-encoding removes EXIF, GPS, and IPTC metadata from outputs. Location data never leaves with the file.
ZIP Downloads
Download a whole batch as one ZIP. Photos are already compressed, so packaging is fast.
Live Preview
See exactly how the selected photo will look, using the same rendering as the final download.
Nothing Uploaded, Ever
Decoding, compositing, and encoding all happen in your browser. Your photos and your logo stay on your device.
Your photos are none of our business.
Watermarking and format conversion run entirely in your browser. Your photos and logo are never uploaded to our servers.
Outputs are re-encoded by the browser, which strips EXIF, GPS, and IPTC metadata. That is intentional: location data does not travel with your files.
Only tool settings (never photos) are stored, in this browser's IndexedDB. Clearing site data removes them.
Built for every everyday use case
