이미지에 워터마크 추가 — 무료

이미지를 하나 또는 여러 개 놓고 텍스트 탭으로 전환한 뒤 워터마크 텍스트(©, ™, 브랜드 이름 등)를 입력하고 글꼴, 색상, 위치, 불투명도, 크기, 회전을 실시간으로 조정하세요. 조정하는 동안 미리보기가 업데이트됩니다. 마음에 들면 이미지 한 장은 다운로드를, 여러 장은 전체 다운로드(ZIP)를 누르세요.

Yes — drop or select dozens of images and the same watermark settings are applied to every one. Output is packaged as a single ZIP so you can save it once and unzip into your delivery folder. Your images are uploaded to our secure server to composite the final watermark and are automatically deleted afterward; we never keep or share them.

둘 다 효과적입니다. 텍스트 워터마크는 설정이 빠르고 읽기 쉽고, 로고 워터마크는 브랜드 정체성을 강화하며 포트폴리오에서 더 전문적으로 보입니다. 클라이언트 갤러리의 경우, 사진 위에 대각선으로 낮은 불투명도의 로고 워터마크를 넣으면 무단 다운로드가 라이선스 수익을 갉아먹는 것을 막을 수 있습니다.

위치 프리셋 9가지(모서리, 가장자리, 가운데) 중에서 선택하거나 "타일(반복)"을 골라 워터마크의 반복 패턴으로 이미지 전체를 덮으세요. 타일 모드는 가장 강력한 도용 방지 방법으로, 이미지를 사용하려는 사람은 모든 영역에서 워터마크를 제거해야 합니다.

대비되는 색을 고르거나(어두운 장면에는 흰색, 밝은 장면에는 검은색) 양쪽 모두에서 잘 보이는 중성 회색을 30~40% 불투명도로 사용하세요. 불투명도 슬라이더는 5%부터 100%까지 5% 단위로 조절되므로 가시성과 미관 사이에서 적절한 균형을 찾을 수 있습니다.

PNG 입력은 PNG로 유지되며(무손실), JPG 입력은 92% 품질로 다시 인코딩되는데, 이는 거의 모든 사진에서 원본과 시각적으로 구별할 수 없습니다. 이 과정에서 EXIF 메타데이터가 제거되어 공개적으로 공유할 때 개인정보 보호에 유용합니다.

Yes. The on-screen overlay you see while adjusting sliders is only a browser approximation; the final watermark is composited on our secure servers for pixel-accurate, full-resolution output, and the file is deleted automatically afterward. We never keep or share your images — but if you need a strict never-uploaded guarantee for confidential imagery, use a desktop watermarking tool that runs fully offline.

Yes — watermarking is free with a generous daily allowance, and we never add our own logo to your output. Batch-watermarking many images at once (e.g. a whole wedding album into one ZIP) is a Premium feature.

아니요. 이것은 워터마크 추가 도구이지 제거 도구가 아닙니다. 소유한 사진에 직접 만든 텍스트나 로고 워터마크를 입힐 뿐, 이미지에 이미 있는 워터마크를 지우거나 편집해 없애지는 않습니다.

The Font dropdown offers six typefaces — system-ui, Arial, Georgia, Courier New, Impact and Times New Roman — covering clean sans-serif, classic serif and bold display looks. The separate Bold checkbox thickens whichever font you pick, which helps small watermark text stay legible at low opacity or small scale.

The Scale slider runs from 2% to 40% of the image and sets how large the text or logo renders regardless of the photo's resolution, so the same setting looks consistent across a batch of differently-sized images. Use 8-15% for a discreet corner mark and 25%+ for a bold, hard-to-crop-out logo watermark.

The Rotation slider swings from -90° to 90° and angles your text or logo diagonally across the photo instead of sitting flat. A 30-45° rotation is a common anti-theft trick because it makes the watermark harder to crop out cleanly while still reading naturally left-to-right.

Yes — the Quick text row offers one-click presets including the current year copyright symbol, CONFIDENTIAL, DRAFT, SAMPLE, DO NOT COPY and PREVIEW. Clicking one instantly fills the watermark text field, which you can still edit afterward if you need a variation.

For a subtle brand mark, use Bottom-right position, 10-15% scale, 30-40% opacity and a color that contrasts gently with your typical backgrounds. For strong anti-theft protection, switch Position to Tile, raise opacity to 40-50%, set rotation to around 30-45° and increase scale slightly — this covers the whole frame so no single crop can remove it.

Upload a PNG with a transparent background for the cleanest logo watermark — a logo with a solid white or colored background will render as an opaque block sitting on top of the photo instead of blending in. JPG logos work too, but only if you're fine showing that background color over every photo. Switch to the Logo tab and use the 'Upload logo' file picker; the live preview updates immediately so you can check the look before applying it.

The on-screen preview is an approximate overlay so it can update instantly as you drag sliders; the actual watermark is composited on the server using precise pixel positioning for each image's exact resolution. Position, scale, rotation and opacity all carry over exactly, but minor differences in font rendering or edge anti-aliasing can appear between the browser preview and the final render. If you're watermarking mixed-size images in a batch, check the downloaded ZIP rather than judging the whole set from a single file's preview.

Every photo you add is uploaded to our backend, which composites the text or logo watermark at full resolution and returns a processed file (or a ZIP for a batch) for you to download — it is not rendered entirely client-side with canvas and JSZip. Files are still handled securely and auto-deleted after processing, the same as every other tool on the site; only the live on-screen preview you see while dragging sliders runs locally, as an approximation of the final server-rendered result.
