Tilføj vandmærker til billeder — gratis

Slip ét eller mange billeder, skift til fanen Tekst, skriv din vandmærketekst (©, ™, brandnavn osv.), og juster skrifttype, farve, placering, gennemsigtighed, størrelse og rotation i realtid. Forhåndsvisningen opdateres, mens du justerer; når du er tilfreds, så tryk på Download for ét billede eller Download alle (ZIP) for hele partiet.

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.

Begge dele virker — tekstvandmærker er hurtigere at opsætte og nemme at læse, mens logovandmærker styrker din brandidentitet og ser mere professionelle ud i en porteføljesammenhæng. Til kundegallerier forhindrer et logo med lav opacitet, vandmærket diagonalt henover billedet, at gratis downloads underminerer dine licensgebyrer.

Vælg mellem ni placeringsforudindstillinger (hjørner, kanter, midten) eller vælg "Flise (gentag)" for at dække hele billedet med et gentaget mønster af dit vandmærke. Flisetilstand er det stærkeste valg mod tyveri — enhver, der vil bruge billedet, skulle fjerne vandmærker fra hvert eneste område.

Vælg en kontrastfarve (hvid på mørke motiver, sort på lyse motiver), eller brug en neutral grå med 30-40 % opacitet, som læses på begge. Opacitetsslideren går fra 5 % til 100 % i trin på 5 %, så du kan finde den rette balance mellem synlighed og æstetik.

PNG-input forbliver PNG (tabsfri); JPG-input omkodes med 92 % kvalitet, hvilket visuelt ikke kan skelnes fra originalen for næsten al fotografi. EXIF-metadata fjernes i processen — nyttigt af hensyn til privatlivet, når du deler offentligt.

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.

Ja — vandmærkning er gratis med en rundhåndet daglig kvote, og vi tilføjer aldrig vores eget logo til dit resultat. Batch-vandmærkning af mange billeder på én gang (f.eks. et helt bryllupsalbum i én ZIP) er en Premium-funktion.

Nej. Dette tilføjer vandmærker, det fjerner dem ikke. Det påfører dit eget tekst- eller logovandmærke på fotos, du ejer; det sletter eller redigerer ikke et eksisterende vandmærke væk fra et billede.

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.
