Add your shop logo to product photos
Branded product photos are recognized at a glance in marketplace search results and social feeds, and they make it harder for others to repost your images as their own. Upload your logo once and this tool stamps it on every product photo ("chèn logo vào ảnh sản phẩm") at the same relative size and position.
For the best look, use a PNG logo with a transparent background, place it in a corner at around 15–20% of the image width, and keep opacity at 80–90% so the product stays the focus.
Check marketplace rules first
Some marketplaces restrict large or distracting logos and watermarks on the main product image. Keep the logo small and in a corner on the cover photo, or use it only on secondary images, and check your platform's current image guidelines.
Your photos never leave your device
Watermarking usually happens right before publishing, while photos are still unreleased product shots, client work or personal documents. Upload-based tools copy those files to someone else's server. Here every image is decoded, stamped and saved inside your browser's memory, and nothing is uploaded. Output keeps the exact original pixel dimensions, and camera metadata such as GPS location is removed from the exported files.
Frequently asked questions
What logo format works best?
A PNG with a transparent background, so only the logo itself appears on the photo. A JPG logo always brings a solid rectangle with it.
What size should my logo be?
Around 15–20% of the image width is visible without covering the product. Because size is relative, the same setting works on every photo in the batch.
My logo is dark and so are my photos. What can I do?
Turn on Soft shadow, which lifts the logo off dark and light areas alike, or upload a white version of your logo for dark photos.
