Compress Images and Add a Watermark in One Step

Check Add watermark on imgadd’s compress page—resize and compress first, then apply your saved watermark style. Configure and preview on the watermark page; everything runs locally.

Product photos, UI screenshots, and client previews often need two things at once: smaller file size for sharing and a text watermark for copyright or “internal use only.”

Instead of running compress and watermark as separate steps, you can enable Add watermark on the imgadd compress page and batch both in one workflow.

Why compress first, then watermark?

imgadd applies compression and resize first, then draws the watermark on the final output image.

That order matters:

  • Predictable text size — Font size settings (e.g. 24px) match what you see on the output image, not a huge original that gets scaled down later.
  • Better quality — The photo is encoded once at the end, avoiding double JPEG loss from watermark-then-compress.
  • Consistent batches — All images share the same output dimensions before the same watermark style is applied.

How to use it

1. Enable Add watermark on the compress page

Open the compress tool and check Add watermark below the output format options.

2. Configure style on the watermark page (new tab)

Click Configure watermark → to open the watermark tool in a new tab:

  • Upload a sample image (not necessarily your full batch)
  • Adjust text, position, opacity, tiling, and more
  • Preview the result live

Settings save automatically in your browser—no account required.

3. Return to compress and run your batch

Switch back to the compress tab, upload your files, set quality, output size, and format, then click Compress.

imgadd reads your saved watermark settings and runs compress → watermark → download for each file.

Output filenames

Download names include clear suffixes:

ScenarioExample
Compress onlyphoto-compressed.jpg
Scaled to 50%photo-50pct.jpg
Compress + watermarkphoto-compressed-watermarked.jpg
50% + watermarkphoto-50pct-watermarked.jpg

ZIP downloads use the same naming.

Which settings apply where?

SettingControlled on
Quality, output size, output formatCompress page
Watermark text, position, opacity, font size, color, rotation, tileWatermark page (auto-saved)

This avoids conflicts like JPEG on one page and WebP on the other.

Good use cases

  • E-commerce / social — Shrink hero images and add a shop or brand watermark
  • Product / sales — Compress UI screenshots and mark them “Internal” or “Draft”
  • Photographers / designers — Send compressed proofs with tiled watermarks

Need watermark only? Use the watermark tool. Compress only? Uncheck the box.

Privacy

As with all imgadd tools, images never upload to a server. Compression runs in a Web Worker; watermarks are drawn on Canvas locally. Preferences are stored in your browser’s localStorage.
