Why creators choose Mark My Pics

We built Mark My Pics for people who watermark photos every day and people who do it once a year. The job is the same either way: get a clean, branded image out of your browser as fast as possible, without giving away your photos or your privacy.

Private by default

Your photos never leave your browser. There is no upload, no cloud queue, and no telemetry on file contents — verifiable by going offline mid-session.

Instant results

Watermarks render at full resolution using your device's GPU and CPU. A single image takes under a second; a batch of ten finishes in the time it takes to find your download folder.

Built for batches

Set your text, font, color, position, and opacity once — Mark My Pics applies them to every photo in your batch and packages the output as a ZIP.

Honest pricing

Free, with a small number of light display ads. No trial, no email wall, no hidden upgrade. Tip with a coffee if it saved you time.

Who Mark My Pics is for

Anyone who shares images online benefits from a clear, consistent watermark. Here are a few of the people we built this tool with in mind.

Photographers

Send watermarked previews to clients before final delivery. Keep your brand on every gallery image you share online.

Etsy & Shopify sellers

Brand your product photos with your shop name so screenshots and re-uploads still trace back to you.

Real estate agents

Mark listing photos with your brokerage logo so syndicated listings always carry your contact details.

Designers & illustrators

Share portfolio previews with a clear copyright stamp without exporting from heavyweight desktop tools.

Teachers & students

Add attribution to classroom resources, project handouts, and shared image libraries in seconds.

Social media managers

Batch-watermark a week of branded content and download everything as a single ZIP.

Common questions

Quick answers to the things people ask most often. The full list lives on our FAQ page.

Is it really free?
Yes — no trial, no sign-up, no credit card. The site is supported by light display ads and optional tips.
Are my images uploaded anywhere?
No. Everything happens in your browser using the HTML5 Canvas API. You can confirm this by going offline mid-session.
Does it work with iPhone HEIC photos?
Yes. We decode HEIC and HEIF files with a built-in WebAssembly decoder so iPhone photos work natively.
How many photos can I do at once?
Up to 10 per batch on the free plan, with all settings applied to every image and a single ZIP at the end.
