Bulk Image Watermark

Stamp your name across an entire shoot in one pass. This bulk image watermark tool takes a folder of photos, draws your text in white at the bottom-right corner of every frame, and returns the lot in a ZIP. You watermark multiple images at once using three controls that apply to the whole set: the text itself, a font size from 16 to 200 px, and an opacity slider from 10 to 100 percent. Photographers batch watermark photos before sending client proofs; sellers mark product shots before they hit a marketplace. A progress bar tracks the run file by file, processing stays on your device, and outputs come back prefixed watermarked- so originals stay distinct.

How to use

01

Add the whole shoot

Drop your images, up to 50 MB each. The tool confirms how many files are ready, and one shared setup gets applied to every single frame in the batch.

02

Type the mark, tune size and opacity

Replace the default watermark text with your credit line, then adjust the Size slider between 16 and 200 px and the Opacity slider between 10 and 100 percent.

03

Run the batch

Click the Watermark button. A progress bar ticks through each file as the text is drawn bottom-right, and the finished set downloads as watermarked-images.zip.

Why Bulk Image Watermark

Common questions

Can the bulk image watermark tool place a logo instead of text?
No, this batch tool draws text only, in bold white at a fixed corner. When you need a PNG logo, custom positioning, or tiling, use the Image Watermark tool, which handles image marks on one photo at a time with full placement control.
How does one font size behave when I watermark multiple images at once?
Size is absolute pixels, so 48 px text looks substantial on an 800 px web image and nearly invisible on a 6000 px camera export. Group files of similar resolution into separate runs and scale the size setting for each group.
Where exactly does the mark land on each photo in the batch?
At the bottom-right corner, inset about 20 px from both edges, on every file without exception. There's no position picker here; that fixed anchor is what makes a 300-file run possible with zero per-image decisions.
What opacity should I pick to batch watermark photos with mixed backgrounds?
The text is always white, so the risk is bright frames swallowing it. Around 60 percent reads well over most content while staying unobtrusive. Before committing, run your brightest image alone and check the corner; if the mark vanishes, push opacity higher.
Does the batch run alter my image formats or quality?
Each photo is re-encoded in its original format at 92 percent quality after the text is drawn, so JPGs stay JPGs and PNGs stay PNGs. The recompression is gentle, but it's one more reason to watermark copies rather than your only masters.
Is there a preview before watermarking 300 frames?
Not a live one, so make your own: load a single typical image, run it, and inspect the download. Once the size and opacity look right on that sample, Clear, load the full shoot, and reuse identical settings.
Will a full shoot process reliably in one browser tab?
Yes, files are drawn one at a time on a canvas and the progress bar shows exactly where the run is. Leave the tab open until the ZIP downloads; building the archive at the end is the longest single step on big batches.
