YOUR PHOTOS. YOUR MARK.

Watermark photos in batches

Add text, your logo, or both to a collection of photos. Preview the placement, then save watermarked copies. Your selected photos are processed on your device, not uploaded to Junocity.

Choose your photos.

A collection. One consistent mark.

Choose JPEG or static PNG photos, or drop them here.

Up to 500 files · 30 MiB and 24 megapixels per photo · maximum edge 8,192 px

Your photos stay on your device. No upload, account, or saved selection.

Add your watermark.

Watermark and export settings

Up to 120 characters. Use a name, studio credit, or “PROOF.”

Position

Proportions follow each photo’s shorter side.

Export settings

Resize never enlarges a photo. Source decode limits still apply.

See it before you save.

Your photo, your signature.

Choose a collection to preview one photo at a time.

Preview is scaled; originals are preserved.

Ready when you are.

Copies made for sharing and proofing.

Exports are re-encoded. Metadata and color profiles may not be preserved; JPEG is lossy. A visible watermark discourages casual copying but does not prevent removal.

Save watermarked copies.

Photos are processed one at a time. ZIP downloads pause between parts to keep memory bounded.

Folder saving depends on browser support. ZIP parts work without folder access.

No photos selected.

Leaving or reloading loses the unsaved batch. Clear/reset releases this page’s references; it does not delete downloaded copies. Cancelling folder saving keeps copies already written.

A CONSISTENT FINISH

How to batch watermark photos.

Choose your photos once, set one text or logo watermark, check it on both portrait and landscape images, then save new watermarked copies. A subtle credit, corner brand, or repeated proof mark can use the same settings across the batch.

  1. Choose your photos.Select supported JPEG or static PNG files, or drop them into the workspace. Start with a few images to check the result.
  2. Set the watermark.Choose text, logo, or both. Adjust placement, opacity, size, and padding. Use a transparent PNG logo to keep its background clear.
  3. Preview, then save copies.Check a portrait and a landscape image if your batch includes both. Choose JPEG or PNG output and save to a folder where supported, or download ZIP parts.

BEFORE YOU START

Practical answers.

Is batch watermarking free?

Yes. Add a text watermark, your own logo, or both without an account. The same settings apply across the batch. There is no AI logo generator; you supply the logo or use text.

How do I watermark multiple photos at once?

Choose your JPEG or static PNG photos, set the text or logo once, preview the placement on more than one image, then process the batch. Junocity applies the same watermark settings to each selected photo and saves new copies rather than changing your originals.

Which image formats are supported?

Choose JPEG or static PNG photos. Logos can be JPEG or PNG; a transparent PNG is useful when you want only the logo shape. RAW, HEIC/HEIF, TIFF, SVG, GIF, animated PNG, PDFs, and videos are not supported. Unsupported or damaged files are reported rather than silently converted.

How many photos can I watermark, and how large can they be?

The queue holds up to 500 files. Each photo must be at most 30 MiB, 24 megapixels, and 8,192 pixels on either edge. Logos are limited to 2 MiB and 4,096 pixels on either edge. Processing works through one full-size photo at a time, but large files can still exceed a device's capacity. Use smaller source images or a smaller batch if processing fails; choosing a smaller output does not bypass input limits.

Are my photos, logo, or watermark text uploaded?

No. Selected images, filenames, image metadata, watermark text, and generated copies are not sent to Junocity or a third-party service. The website loads its own code normally, then processes your selected files locally. Your selection and settings are not automatically saved. Closing or refreshing the tab loses the unsaved batch. Downloads and browser-managed temporary files can use your device's disk. Read the privacy details.

Will the saved copy have the same quality and metadata?

Export re-encodes the image. Keeping the original pixel dimensions does not preserve the original file bytes, and JPEG output is lossy. PNG output keeps transparency; exporting a transparent PNG photo as JPEG requires an explicit background choice. EXIF, IPTC, GPS, original DPI, and color-profile metadata may not be preserved. Professional print or HDR color fidelity is not promised. Keep your originals and review the saved copies before using them for proofing, sharing, or web delivery.

Can I save to a folder instead of downloading a ZIP?

Folder saving appears only when the browser supports it and requires your explicit permission. Other browsers can download ZIP parts. Each part is bounded so the tool does not keep the entire finished collection in one archive; save the current part before continuing. Your browser or device may still need space for the download.

Are my original files changed? What happens if I cancel?

The tool creates new watermarked copies and does not edit your original photos. Cancel stops the batch, but it cannot delete copies you have already saved. Clear / reset releases the tool's current selection and results; it does not erase browser or operating-system copies, or files you downloaded.

Does a watermark prevent copying?

A visible watermark identifies a version of an image; it can still be cropped, edited, or removed. It does not establish ownership or guarantee protection from copying. Use photos and logos you own or have permission to use.
