Why choose Fogkits
Protect drafts and client proofs without a cloud hop — same workspace chrome as Crop and Rotate.

Text and logo stamps stay in the tab. Private portfolios never leave this device for this tool — the differentiator vs cloud watermarkers.

Copyright strings, brand names, or a transparent PNG logo — switch modes without leaving the page.

Opacity, size, rotation, and position update the Preview stage as you drag — encode only when you download.

Nine-point position grid plus Tile / repeat so a casual crop cannot wipe every mark.

Stamp up to 20 images with one recipe, download selected, or Download all as a ZIP when zipArchive is available.

Orient or crop first, then watermark — or compress and convert after for delivery.

Illustrative still. Drop a real photo above to watermark in your browser.
Proof
Cloud watermark tools ask you to upload first. Fogkits keeps the file on this device, lets you place text or a logo with live preview, and hands you JPG/PNG/WebP you can send to clients. The still is illustrative — drop your own image above for a live run.
Text + logo
Switch modes; PNG logos keep transparency.
Tile option
Repeat marks so crops cannot wipe them all.
JPG default
Quality 92 — widely compatible export.
Batch ZIP
Up to 20 images when zipArchive is in the build.
Use cases
Three everyday jobs where a quick stamp protects work before it leaves your device.

Client proofs
Tile a soft © mark on gallery proofs so drafts are not reused as finals — export JPG and send without uploading the album.

Brand & portfolios
Upload a transparent PNG logo, place bottom-right or center, dial opacity, then batch-export a WebP set for the site.

Social & listings
Add a corner brand mark to listing photos before Instagram or marketplaces — then compress if the portal has a size cap.
Drop a photo above, tune text or logo with live preview, pick JPG/PNG/WebP, and download when the Result looks right.
Yes. Fogkits draws text or logo watermarks in your browser and encodes the result locally. The file never leaves this device for this tool.
Yes. Browser-local watermark is free — no account and no credits. Export JPG, PNG, or WebP when the Result preview looks right.
Yes. Switch to Image mode, upload a PNG/JPG/WebP logo (transparency works best), then size, opacity, rotate, and place it like text — including tile/repeat.
Tile spreads the watermark across the photo in a diagonal-friendly grid so a single crop cannot remove every mark. Opacity and rotation still apply.
JPG is widely compatible for email, portfolios, and social uploads. Switch to PNG when you need transparency in the base image, or WebP for a modern web format.
Yes. Add up to 20 images, apply the same watermark recipe and output settings, Watermark all, then download selected or Download all as a ZIP when zipArchive is present in the Fogkits build.
