MarkCraft is a free client-side watermark generator: transparent PNG seals or live photo overlay (up to 100 images), square/fixed canvas with white pad, layout presets, gradients, logos, batch ZIP export, and portable settings JSON.
Context
Teams need confidential grids, brand seals, and photo credits without sending images to a third-party SaaS. Designers also want real typography control, not a single fixed stamp.
Approach
Everything runs in the browser on Canvas: seven layout engines (grid, badge, signature, security stripe, hologram, glass card, curved seal), freeform fonts, multi-photo queues with optional fixed square output and white letterbox, drag-to-position, and exportable markcraft.settings files for reuse after product updates.
Result
Open https://beoops.com/project/watermark, pick a template, tweak type and color, then download PNG/JPG or batch ZIP — no install, no server-side image processing.
MarkCraft Studio is a free browser watermark generator by beoops. It creates transparent PNG brand seals and photo overlays (grid tiles, corporate badges, signatures, security stripes) entirely client-side — images are not uploaded to a server.
Fully client-side processing — no image upload to a server

Frequently asked questions
What is MarkCraft Studio?+
MarkCraft Studio is a free online watermark and brand seal generator from beoops. It runs in the browser and can export transparent PNG watermarks or overlay marks on photos, with templates for confidential grids, seals, and signatures.
Is MarkCraft free?+
Yes. MarkCraft is free to use at https://beoops.com/project/watermark with no account required.
Does MarkCraft upload my photos to a server?+
No. Watermark rendering runs client-side in your browser. Your photos are not uploaded to beoops servers for processing.
Can I watermark multiple photos at once?+
Yes. Photo overlay mode supports a queue of up to 100 images and batch ZIP export as PNG or JPG.
Can I export a transparent PNG watermark only?+
Yes. Standalone (純 PNG 水印) mode exports a transparent PNG mark you can place on any asset in design tools.
Can I save and reuse my watermark settings?+
Yes. Export a portable markcraft.settings JSON file and re-import it later. The format uses a stable schemaVersion so future site updates can still read older files.
How do I make a square watermarked photo with a white background?+
In photo overlay mode, open the Canvas tab, choose fixed size (e.g. 1080×1080 square), set fit to contain (letterbox), and use white (#ffffff) as the pad color.
