Frequently Asked Questions

Are my files uploaded to any server? +

No. MediaWatermark Pro processes everything 100% locally in your browser. Your photos, videos, and PDFs never leave your device. We use client-side technologies like Canvas API, FFmpeg.wasm, and pdf-lib — no server uploads, ever.

What file formats are supported? +

Images: JPG, PNG, WebP, GIF, BMP, TIFF, SVG, HEIC
Videos: MP4, MOV, AVI, WebM, MKV
Documents: PDF
Export formats include JPG, PNG, WebP with adjustable quality settings.

What are the free plan limits? +

Free users get 20 exports per day (resets at midnight). Guest users (not signed in) get 3 exports per day. Upgrading to Pro ($9.99/mo or $7.49/mo yearly) gives you unlimited exports with no daily limits.

Is there a file size limit? +

Since processing happens locally on your device, file size limits depend on your browser's memory. Typically, images up to 50MB and videos up to 500MB work well. For very large files, we recommend using Chrome or Edge which have higher memory limits.

Can I cancel my Pro subscription? +

Yes, you can cancel anytime from your Profile Panel in the editor. Click your avatar → Manage Subscription. Cancellation takes effect at the end of your current billing period. We also offer a 7-day refund policy — see our Refund Policy for details.

Which browsers are supported? +

MediaWatermark Pro works best on Chrome, Edge, Firefox, and Safari (desktop). Mobile browsers are also supported with a responsive interface. For the best experience with video processing, we recommend a Chromium-based browser.
